L is for Lost Colony

worthingsaga As we discussed in I is for Interstellar, space colonization is a major theme of science fiction, especially space opera. Of course, things don’t always go smoothly. Space is a really, really, really big place, and sometimes, due to war or famine or simple bureaucratic mismanagement, colonies get cut off from the rest of galactic civilization. They become lost colonies.

Some of my favorite stories are about lost colonies: either how they became cut off, or how they reintegrate after so many thousands of years. In many of these stories, the technology of these colonies has regressed, sometimes to the point where the descendents may not even know that their ancestors came from the stars. When contact is finally made, the envoys from the galactic federation may seem like gods or wizards.

Because of this technological disconnect, stories about lost colonies often straddle the line between science fiction and fantasy. After all, Clarke’s third law states:

Any sufficiently advanced technology is indistinguishable from magic.

Of course, the line between science fiction and fantasy has always been a fuzzy one. Hundreds of attempts have been made to define it, but they all fall short. In the end, it often breaks down to certain recurring tropes, like dragons and wizards versus ray guns and rockets, but even that doesn’t always work.

For example, Anne McCaffrey’s Dragonriders of Pern is technically about a lost colony far into the future, but it’s got dragons and castles and other tropes that belong squarely in fantasy. Then again, the dragonriders have to fight alien worms who invade every few dozen years from a planet with a highly elliptical orbit, so there’s still a strong science fiction basis undergirding the whole thing.

And that’s just Dragonriders of Pern. What about Marion Zimmer Bradley’s Darkover series, or C.S. Lewis’s Space Trilogy? Trigun is more western than fantasy, but it’s also full of sci-fi tropes like giant sand-crawling monster ships and a weird post-apocalyptic backstory. And then there’s all the Japanese RPGs that combine magic with mechas, with Xenogears as one of the best examples. For a distinct Middle Eastern flavor, look no further than Stargate.

It’s no coincidence that all of these stories feature a lost colony of one kind or another. When the characters don’t know that they’re living in a science fictional universe, it’s very easy to throw in tropes from other genres. By no means is it required–Battlestar Galactica and Dune are evidence enough of that–but they certainly present the opportunity to do so. After all, lost colony stories basically present a hiccup in humanity’s march of progress, breaking the essential science fiction narrative for all sorts of interesting side stories and tangents.

One perennial favorite of science fiction writers is to suggest that Earth itself is a lost colony from some other galactic civilization. That forms the entire premise behind Battlestar Galactica: the original twelve colonies have been destroyed in the human-cylon wars, and the last few survivors are searching for the legendary thirteenth colony of Earth, hoping to find some sort of refuge. Apparently, Ursula K. Le Guin’s Hainish cycle also plays with this trope, though she’s never very explicit with her world building. It can be a bit tricky to twist the lost colony trope in this manner, but if pulled off right it can really make you sit back and go “whoa.”

My personal favorite is probably Orson Scott Card’s The Worthing Saga, about a colony of telepaths that breaks off from a collapsing galactic empire and actually becomes more advanced than the rest of humanity. When Jason Worthing and Justice re-establish contact, the descendents of the galactics are basically pre-industrial subsistence farmers who view them as gods–which, in a certain sense, they almost are.

It’s a great story that really entranced me, not just for the science fictional elements but also for the distinct fantasy flavor. Orson Scott Card’s handling of viewpoint in that book is truly masterful, so that I felt as if I were viewing everything through the eyes of his characters. Since the farmers don’t know anything about their spacefaring ancestors, all the parts from their point of view feel like a completely different story. It was really great.

My first novel was actually a lost colony story, combined with a first contact. I trunked it a long time ago, but many of the earliest posts on this blog are all about my experience writing it. As for my other books, Desert Stars contains elements of this, though the lost colony in question is actually a nomadic desert society that lives on the capital planet of the galactic empire, just outside of the domes where all the more civilized folk live. Heart of the Nebula is basically about a society that puts itself in exile in order to escape the privations of the Hameji. And in… no, I’d better not spoil it. 😉

The lost colony isn’t one of the flashier or more prominent tropes of science fiction, but it’s definitely one of my favorites. It’s a great way to add depth and intrigue, as well as bend genres. For that reason, I think this trope does a lot to keep science fiction fresh.

K is for Klingon

Ah, the proud warrior race. Where would science fiction be without it? From Klingons to Ur-Quans, Wookies to Sangheilis, Mri to Green Martians to Vor Lords, warrior races have been a staple of space opera and space-centered science fiction pretty much since the genre was invented.

The concept behind this trope is the same as the one behind blood knight: honor is more valuable than life, and the best way to win or defend honor is through combat. It’s not necessarily death that these guys live for, so much as glory and a chance to prove their prowess. Unlike the always chaotic evil races, these guys usually follow a strict code of honor, sometimes to the point of absurdity.

When taken too far, of course, you get a planet of hats, where everyone has exactly the same values without any kind of depth or diversity. Fridge logic leads to Klingon Scientists Get No Respect. After all, how did the Klingons build starships and discover space travel if they’re all constantly fighting each other?

Fortunately, we have plenty of real-world examples for how this sort of thing works. Lots of human cultures have placed a high value on warrior qualities, including the Spartans, the Samurai, the Vikings, and the Mongols, just to name a few. Of course, relying on stereotypes may lead to some unfortunate implications, so it’s not a good idea not to have too narrow or ethnocentric a reading of history. Still, there’s a lot from history that we can glean.

In fact, you could make a valid argument that humans are the quintessential warrior race. After all, we developed the technology to annihilate our own species before we put a man in space. Even today, the amount of resources we spend on war and security far outstrips the amount of resources we dedicate to just about any other pursuit. From the earliest ages, we engage in competitive physical sporting activities that mimic warfare and video games that outright simulate actual combat. Our everyday language is full of violent terms like “on target,” “wiped out,” and “having a blast,” to the point where most of them are invisible. Indeed, if we ever make contact with an alien race, we may very well find that we are the Klingons.

In that respect, this trope is just another way that science fiction acts as a mirror through which we can better see ourselves. The proud warrior race fascinates us because we have so much in common with them. Klingons are not just faceless orcs for the good guys to slay by the dozen–in many sci-fi universes, they (or individual members) actually become good guys. Just think of Worf from Star Trek, or The Arbiter from Halo, or Aral Vorkosigan from Louis McMaster Bujold’s Vorkosigan Saga. While on the surface, these guys seem absolutely crazy, when you start to explore them you frequently find a lot of depth.

I am fascinated by the concept of a warrior race. I’ve played with it quite a bit in my own work, especially with the Hameji in Bringing Stella Home, Sholpan, and Stars of Blood and Glory. The Hameji are an entirely spacefaring society that lives on the outer fringes of space, beyond any terraformed planets. Because they live entirely on spaceships, they must capture and repurpose new spaceships just to have enough living space to expand their families. Since their battleships also house their families, they make no distinction between military and civilian, and live by an extremely rigid social hierarchy with the patriarchal captain at the top and everyone else under his command. Life is a privilege, not a right, and disobedience is strictly punished since it has the potential to put everyone’s life at risk.

As a result of all this, the Hameji are extremely vicious and warlike, living by a moral/ethical code that runs completely counter to our modern sensibilities but makes perfect sense to them. They think nothing of slagging entire worlds and killing billions of people because to them, a world is a giant starship, and all those billions of people are so many enemy warriors. They look down at the planetborn as weak because of their lack of discipline and obedience, and think nothing of enslaving them due to their strict social hierarchy. In fact, because resources are limited and life is a privilege granted by the ship’s captain, the Hameji prefer to space their prisoners rather than keep them alive.

Man, those books were fun to write. 😀 Brutal, but fun. Because the weird thing is, as much as you abhor a culture whose values contradict your own, when you really understand them, you can’t help but feel something of a connection. You might not love them, but you respect them, and in a strange sort of way sympathize with them. I’m not sure if that’s the experience with the Hameji that my readers have had, but that’s definitely been my experience in writing them.

So yeah, I’m definitely a big fan of the proud warrior race. Expect to see me play with it many more times in the future.

J is for Jedi

As much as science fiction looks to the future, it also of necessity looks to the past. And as much confidence as it places in the scientific method, it often turns to religion, simply because of the scope of the great cosmic questions that such stories inevitably pose.

For these reasons, it should come as no surprise that the best science fiction stories often include knights and shamans, priests and warrior monks. Far from degrading our view of the future, they greatly enrich and humanize it, bringing a sense of meaning and destiny to an otherwise cold and lonely universe.

The best example of this is probably the Jedi from the original Star Wars trilogy. I still get shivers when I hear Yoda explain the force:

Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well you should not. For my ally is the Force, and a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter. You must feel the Force around you; here, between you, me, the tree, the rock, everywhere, yes. Even between the land and the ship.

There are plenty of other examples too, of course–harsh ones like the creeds the Cylons follow in the re-imagined Battlestar Galactica, which they use to justify their genocidal war against the humans. And then there are the quaint and simplistic ones that happen when a primitive race makes first contact with humanity … as well as the ones from a race so advanced that they make us look like barely evolved monkeys.

So why is religion so prominent in science fiction? Probably because the best science fiction stories act as a mirror that allows us to see ourselves better. Throughout history, religion has been one of the most important parts of any human civilization. Even the modern secular cultures still grasp at the same cosmic questions, striving to find meaning beyond the animal drives of food, sleep, and sex.

At its core, every religion is about telling a cosmic story. There’s a reason why the Bible starts with the words “in the beginning,” and why the first sura of the Qur’an names Allah “The Merciful and The Compassionate.” Since the best science fiction also tells a cosmic story, is it any surprise that there should be overlap between the two?

The best science fictional religions are the ones that make you want to believe. The Force in Star Wars was definitely like that to me (the original trilogy, of course–before all that midi-chlorian nonsense). Orson Scott Card’s philotic web also turned me into a believer, at least for the duration of those books. Even Eywa from the movie Avatar had some deep undertones that made me wish I was a part of that world.

Religion plays a huge role in my own books, not just the stuff that I believe in real life (though I’m sure that influences my writing), but the stuff that I think the characters would believe.

In Star Wanderers, for example, most of the outworlders are pagans who pray to the stars. In that universe, astrogation is an act of worship. The Deltans subscribe to a fusion of pagan and Christian beliefs, which in turn affects how much they value families and children. I won’t spoil it, since it comes as something of a reveal in Homeworld, but it definitely drives the series. And of course there’s Jeremiah’s New Earther background, with its guilt complex that leaves him emotionally scarred.

My favorite religion to write so far was the faith of the desert tribesmen in Desert Stars. I wrote that book just after spending a summer in the Middle East, and my experience of the Muslim culture definitely was a huge influence. The tribesmen pray to the Temple of a Thousand Stars, the temple erected to the memory of Earth soon after the first colonists made planetfall. The first half of the book follows Jalil’s pilgrimage to the ancient temple, through the domes filled with strange and decadent people.

When I started the Gaia Nova series, I wanted to create a science fictional universe where any of our real-world religions could still plausibly be true. The way I got around all the conflicting prophecies of the end times was to have a human colony mission leave Earth soon after our time. When the colonists woke up, they’d lost the location of Earth, so naturally all the religions developed around the idea that Earth had received its prophesied glorification and become a heavenly paradise.

That’s the short explanation, anyways. But the books themselves aren’t so much about that as they are about the characters. If religion is important to them, then that becomes an important part of their story. And since religion is so important to us here on Earth, I can’t help but believe that it will follow us to the stars.

I is for Interstellar

Right after I went through my Dinosaur phase, I saw Star Wars IV: A New Hope for the first time. Instantly, all that childlike excitement and exuberance was transferred from paleontology to astronomy. We had a series of about twenty astronomy books in my elementary school’s LRC (Asimov’s astronomy series, I believe–the ones with the gray dust jackets), and in about a year I’d read them all.

Star Wars was fun, but what was really fascinating was learning about the stars. When I started to grasp the scale of our galaxy–that if our solar system was the size of a milk carton, the Milky Way would be the size of North America–my mind was totally blown. Quasars, pulsars, black holes, white dwarfs, red giants–it was so amazing! And then, when I started thinking about all the other worlds out there, and what it would be like to visit them–that’s when I became a science fiction fan for life.

It goes without saying that you can’t have space opera without setting the story somewhere in space. But the best space opera goes much further than that–it’s about space as the final frontier, and humanity’s ultimate destiny among the stars. After all, if we as a species stay put on this pale blue dot, sooner or later we’ll kill ourselves off or suffer another mass extinction event that wipes us all out like the Dinosaurs.

For that reason, classic space opera often takes undertones of manifest destiny, except on a galactic scale. The stars are not just interesting places to visit, they’re absolutely crucial to our survival, and no matter what alien dangers await us, we will face them boldly and either conquer or be conquered.

Of course, not all space opera stories take place during the exploration and colonization phase of human interstellar expansion. Plenty of stories take place thousands of years later, once humanity has comfortably established itself among the stars. Even so, there are still more than enough wonders remaining to be explored–if not for the characters, then for the readership. The vastness of space is so great that there really is no end to it, and the possibilities are only bounded by the writer’s imagination.

One of my favorite space opera computer games is Star Control II, also know as the Ur-Quan Masters. In the game, you’re the captain of a giant starship built with alien precursor technology. The races of the Federation, including humanity, have been defeated and enslaved by an aggressive warrior race known as the Ur-Quan. You must travel from star to star, gathering resources to upgrade your starship and convincing the other alien races to join the new alliance.

By far, the best part about that game is the starmap. It’s HUGE! More worlds than anyone can possibly visit in any one playthrough, or five, or even ten. And each alien race has its own history, its own culture, its own set of goals and objectives–and oftentimes, most of these goals have very little to do with the actual conflict of the game. In fact, there are some races like the Arilou which don’t even seem to know that there’s a war going on. They’re much more interested in something frightening and mysterious from another dimension that they never quite explained, but that may involve the Orz somehow…

With each new world that you discover, you learn that the galaxy has a very, very, very long history. So long, in fact, that the human race has only really existed for a blip in time. The other races are involved in their own disputes, and many of these go back to the times when our ancestors were swinging through the trees somewhere in central Africa. But whether or not we want to be a part of it, we’re involved, simply by virtue of where our star happens to be located.

The best space opera isn’t just about our world: it’s about our place in a much wider universe. Whether it’s a serious tale about humanity’s ultimate destiny, or an action-packed intergalactic romp, there’s always that sense of something greater than us–that same sense of wonder that gripped me as a boy when I first started to learn about the stars.

H is for Hologram

In real life, the term “hologram” means something fairly specific. But in science fiction, it can mean a number of different things.

For example, in Star Wars it’s basically a three dimensional video recording projected on a flat surface. In Halo, it’s the visual form that the AI character Cortana takes when she wants to interact with the Master Chief. And in Star Trek, the holograms actually have a degree of physical substance, so that in some episodes they go rogue and try to take over the ship.

The basic underlying idea, though, is the same: blurring the line between the virtual world and the real world through a virtual projection that we can interact with. And in that sense, this is actually an area where science fact is fast catching up with science fiction.

Some sub-genres, such as cyberpunk, focus almost solely on the tension between the real and the virtual. Often set in a near-future world, cyberpunk stories often feature a crapsack future, from which the only meaningful escape is a virtual reality. But the thing about virtual realities is that they can be reprogrammed in such a way as to give the ones controlling it almost absolute power over the lives of the people inside. For that reason, the main characters are often hackers, struggling against the corporate evil overlords.

But holograms aren’t restricted to cyberpunk. They’re quite common in space opera, too, and not just because they’re cool. For one thing, they can be really useful for training simulations (which often leads to holodeck malfunctions, courtesy of the rule of drama). They can also be useful as disguises or decoys, especially in the Halo series.

But perhaps the most memorable holograms are the ones who develop a close relationship with their real-world human counterparts. This may include romance, which, combined with the existential angst that typically surrounds androids, robots, and cyborgs, makes for some very interesting tension. A good example of this is Cortana from the Halo series, an alien AI who took on a younger form of her human handler, Doctor Halsey, and then developed a very close relationship with her Spartan bodyguard, the Master Chief. It never actually went anywhere (at least in the main series arc), but it certainly made for an interesting story.

Jane from the Ender’s Game series would probably be my favorite hologram, though she’s more of a shapeshifting AI who can take many different forms, depending on what suits her. Cortana is definitely up there too. I haven’t used this trope much in my own fiction yet, but I’m playing with it in Heart of the Nebula, a currently unpublished direct sequel to Bringing Stella Home. Not sure exactly where I want to take it yet, but it should be interesting.

G is for Gravity

cmdr_hadfield_juggling — Commander Hadfield planning a zero-g easter egg hunt earlier this month on the ISS.

Possibly one of the most defining aspects of space is the sensation of free fall. Of course, gravity exists in space, the same as it does everywhere else in the universe (probably), but in space we feel its effects differently because we aren’t close enough to a body of sufficient mass to feel a strong pull. That, and our spaceship itself is also in free fall, so if that’s our frame of reference we feel no weight because there’s nothing for weight to push back on … but that’s a concept probably best left for O is for Orbit.

The thing is, as fun as weightlessness can be, in the long-term it can have some negative health effects, such as deterioration of bone and muscles, weakening of the immune system, etc. The effects of micro gravity on human fertility are not very well-studied, but there’s some speculation that conception and gestation would be impossible, since embryos need gravity in order to implant properly. Humans are adapted to live on the surface of Earth, and that means living with a constant 10 m/s² or so of gravitational acceleration.

For future space colonies and spacefaring civilizations, this means we need to find a way to simulate the effects of gravity in a micro-gravity environment. There are a few common ways to deal with this problem:

Artificial Gravity — Applied phlebotinum that creates a field within which the gravity is normal. A necessary weasel hand wave that you’ll see most often in soft sci-fi and space opera, where the plot and characters are more important than the science.
Centrifugal Gravity — The illusion of gravity created by spinning a can-like spaceship or space station in a circle, pressing the humans against the inside wall. You’ll see this in both hard and soft sci-fi. Scale it up, and you get Ringworld Planets.
Powerful Starship Drive — If your starship drive is powerful enough, it can accelerate you at 10 m/s², effectively creating the sensation of gravity. Your starship will be like a flying skyscraper, where “down” is in the direction of the engines. At this rate of acceleration, you should reach 99.9% the speed of light in about a year, which opens up all sorts of possibilities for relativistic space travel (provided you have a sufficiently massive energy source to sustain that reaction). Just be sure to give yourself the same amount of time to decelerate, otherwise bad things may happen.
Baby Planet — An asteroid no larger than a small asteroid that still, for some reason, has normal Earth-like gravity. Think Le Petit Prince. Not nearly as common as the other three, but the existence of gravitational waves means that it may be possible (or at least plausible) to create gravity generators that work this way.
Roll with it — Yeah, so everything is weightless in space. So what? Deal.

Another problem related to gravity is rapid deceleration. Unless you don’t mind splattering everyone in your starship all over the walls and ceilings, you can’t go from zero to near-light speeds (or vice versa) without some way to counteract the sharp change in momentum. Space opera and soft sci-fi gets around this by using inertial dampers–basically, magical devices that give the starship a nice, soft ride (unless you want the bridge to explode, of course). As you might expect, stories on the harder side of sci-fi tend to play around with this a lot more.

My first exposure to artificial gravity came when I read a comic book version of The Norby Chronicles by Isaac Asimov. The characters had a device that would basically allow them to levitate, and I thought that was so cool. It wasn’t until I read the Corellia Trilogy by Roger Allen McBride that I realized that every starship in the Star Wars universe had a machine that could manipulate gravity like this. At one point, the artificial gravity generators on one of the ships failed. My mind was blown, and I’ve never looked at gravity the same since.

I tend to write stories where the characters and plot are more central than the science, so I’ll often just fall back on the standard artificial gravity field like most space opera. During combat maneuvers, though, things get a bit more tricky, with dampers on the bridge that mitigate (but don’t erase) the worst effects of rapid deceleration, and special coffin-like chambers for the crew below decks to keep them from getting splattered. In my Star Wanderers series, I also use centrifugal gravity for the larger space stations, since I figure the energy costs of artificial gravity tend to scale up.

In short, science fiction stories that address the problem of gravity in a real and thoughtful way tend to be a lot more believable and immersive, even if the solution to the problem is basically magic. As with anything in science fiction, there are so many imaginative ways of dealing with the problem that it’s actually more of an opportunity than anything else.

F is for Faster Than Light

Remember that moment in Star Wars when the Millennium Falcon went into hyperspace? When Harrison Ford shouted “go strap yourselves in, I’m going to make the jump to light speed,” and the sky lit up as the stars streaked by? That was my first introduction to faster-than-light (FTL) travel, and I haven’t looked back since.

FTL is a major recurring trope in space opera, and not just because of how cool it is. If you’re going to have a galactic empire, you need some way to get around that empire–or at least some way to transmit information without too much difficulty. The distance between star systems is measured not in miles or kilometers, but light years–that is, the distance that a particle of light can travel in one year. Considering how the nearest star to Earth, Proxima Centauri, is ~4.24 ly away, you can see the need for some sort of magical technology to bridge the distance.

FTL travel comes in four basic flavors:

Warp Drives — The ship breaks the speed of light as easily as our modern fighter jets break the speed of sound. Impossible to justify, except through hand-waving. The most prominent example of this is Star Trek.
Jump Drives — The ship disappears from its current position and reappears somewhere else. Also requires hand-waving, but is at least a little easier to justify. Battlestar Galactica is a good example of this, as is Schlock Mercenary.
Hyperspace Drives — The ship enters an alternate dimension which allows it to travel faster through our own. The alternate dimension is called ____space, usually “hyper” but also “quasi,” “x,” etc. Star Wars is the classic example, though Star Control II took things a step further by having a hyperspace dimension within hyperspace.
Wormgate Network — The ship (or maybe just the passengers) enters a portal which transports it to a portal somewhere else. A network of these portals allows travel throughout the galaxy. Stargate and Babylon 5 use this method.

An alternate way to do it is to make FTL travel impossible, but hold the galactic empire together through FTL communication. This technology, known as the ansible, features prominently in Ursula K. Le Guin’s books and the Ender’s Game universe. It has some really interesting implications: for example, even though planets can communicate instantaneously with each other, it takes almost 40 or 50 years to go from one to another, but at near-light speeds, it feels as if only a few months have gone by. Thus, if you’re going to travel to another world, you have to leave everything behind, including your family and loved ones. By traveling from world to world, you can skip entire generations, spreading your natural lifespan across thousands of years of normal time.

In writing FTL, one thing you have to be really careful about is to keep in mind ways in which the system can be abused. For example, if jump drive technology makes it possible to instantaneously transport anything anywhere in the universe, then you can bet that someone is going to send a bomb into the White House (or whatever the equivalent is in your fictional universe). Thus, the invention of unrestricted jump drive technology will lead to a very short and brutal war.

This actually happened in Schlock Mercenary, and the solution was Terraport Area Denial (TAD) zones, or broad areas of space where a force field prevents anyone from either jumping in or out. Thus, anyone who wants to visit a planet in a TAD zone has to jump to the edge of the field and travel the rest of the way at sublight speeds.

FTL isn’t always appropriate for a science fiction story. If the story is supposed to lean more toward hard sf, then it’s probably better to stick with our current understanding of the rules of physics, which state that nothing can travel faster than the speed of light. Still, with things like quantum entanglement and other recent discoveries, if you know the science well enough, even the speed of light might not be an upper limit. But for the rest of us mortals, FTL is basically just magic–a sufficiently explained magic, perhaps, but magic nonetheless.

Personally, I’m a fan of the jump drive form of FTL. That’s the one I use the most in my own books. The cost is that the further distance you try to jump, the harder it is to pinpoint exactly where you’ll end up. To overcome this, you can use jump beacons to draw out anyone trying to jump into your particular sector and have them exit jumpspace next to the beacon. This comes in handy in combat, when the enemy tries to jump a nuke onto your ship.

In the later Gaia Nova books, FTL is facilitated by jump stations spread out in a line across space, with reactors powerful enough to jump ships rapidly to the next point along the line. In the earlier Star Wanderers books, that technology hasn’t been invented yet, so there’s still an Outworld frontier.

It gets kind of complicated, but it’s lots and lots of fun to world build. For example, how does a particular change in the FTL tech alter the galactic balance of power? When settlers try to colonize a new system, what do they establish first–starlanes, jump beacons, Lagrange outposts, or what? As with any magic, changing one thing affects everything else, which also affects everything else, which … yeah, you get the picture.

E is for Empire

Almost every far future science fiction story has a galactic empire of some kind. From Dune to Foundation, from Star Wars to Firefly, there’s always someone trying to rule the galaxy, often in a way that makes life difficult for the protagonists.

Why? Rule of drama, of course, but also because it gives the story a truly epic scope. Just as the classics such as Homer’s Iliad and Tolstoy’s War and Peace are as much about entire civilizations as they are about the people characters within them, so it is with science fiction, especially space opera. Combine that with science fiction’s forward-thinking nature, and you have the potential for some truly amazing stories about humanity’s destiny among the stars.

But why empire? Because even if we make it out to the stars, we’ll probably still take with us all of the baggage that makes us human. Science fiction may be forward looking, but history repeats itself, and you can’t have a clear view of the future without understanding and acknowledging the past.

Not all galactic empires are evil, but most of them are. We shouldn’t have to look further than the real-world history of Imperialism to see why. Oppression, exploitation, slavery, genocide–all of these have been done in the name of Empire, and many more evils besides. Even benevolent hegemonic powers (such as, I would argue, the United States of America) often end up doing great harm, either through action or inaction.

Of course, all of this makes for some really great stories. When Asimov wrote his Foundation series, he quite literally based it on The History of the Decline and Fall of the Roman Empire by Edward Gibbon. When Frank Herbert wrote Dune, he drew extensively from his background as an orientalist and based the overworld story on the Muslim conquests of the 7th and 8th centuries. Star Wars is based loosely on the collapse of the Roman Republic, and Firefly echoes many of the old Western tales of former Confederate soldiers heading west after the US Civil War.

It’s worth pointing out that the Galactic Empire is by no means the only form of political organization in space opera. There are actually several, including:

The Federation — A loose organization of stars and planets that usually exists to foster cooperation and mutual peace between galactic civilizations. Rarely evil, but can be crippled by red tape.
The Republic — A more centralized version of the Federation, typically. Exercises more control over its citizens, but not in an oppressive way. Usually features some form of representative government.
The Alliance — A team of political underdogs united to overthrow the Empire and establish a more just form of government in its place. If they win, they usually become the Republic or the Federation.
The Kingdom — A smaller government within the larger political system, often struggling for survival against more powerful forces. Not always democratic, but is often good, at least to its own citizens.
The Hegemonic Empire — Like the Empire, but rules primarily through soft power, ie co-opting their enemies rather than crushing them. May overlap with the Republic or the Federation.
The People’s Republic of Tyranny — The Empire pretending to be the Federation.
The Vestigial Empire — What the Empire becomes when it’s been defeated but not yet destroyed. Still oppressive and evil, but rules a smaller territory and struggles for relevance and survival.
The Remnant — An element from the Alliance that’s gone rogue. The war may be over, but these guys are still fighting it, even if they’ve lost sight of what they’re fighting for.
The Horde — A highly aggressive and expansionist warlord state. By far the most violent and brutal of any political organization, it seeks to conquer and subjugate the entire galaxy.

As a political science major, all these forms of government really fascinate me. I’ve played with quite a few of them, especially the Horde (Bringing Stella Home), the Empire (Desert Stars), the Hegemonic Empire (Star Wanderers), the Kingdom (Stars of Blood and Glory), and the Remnant (also Stars of Blood and Glory). You can definitely expect to see me play with them again in the future.

D is for Droids

Some of the best-loved characters in science fiction don’t even have a heartbeat. Why? They’re robots, that’s why!

Unlike the mechanical “slaves” (the original meaning of the Czech root robota) that built your car or enable your GPS devices, these robots are a lot more human. In fact, the word “droid” is short for “android,” which comes from the Greek root for “man” (andr-) and means “manlike.”

In other words, the thing that defines these robots is that they blur the line between machine and man. And ever since they made their first appearance in some of the earliest works of science fiction (Frankenstein by Mary Shelley was arguably the first), that’s exactly what they’ve been doing.

Star Trek loves to play with this trope, from Data in The Next Generation to the doctor in Voyager. But where the droids in Star Trek tend to be angsty and existential, the ones who populate Star Wars already know their place and don’t have any qualms filling it.

My first exposure to droids was when I saw the original Star Wars trilogy as a little boy. An image of C3PO with his golden humanoid body wandering across the dune wastes of Tatooine will probably be stamped on my subconscious forever. That, and the little traveling flea market the Jawas ran from their sand crawler.

One of the neat things about droids is that you can go either direction with them. If you want to get all existential about the nature of humanity and whatnot, you can use them to explore those questions since they’re almost human but not quite. On the other hand, if you just want an exciting space romp with some unique and interesting characters, you can bring them out as regular characters.

An advantage that droids have over humans is that they’re harder to kill and easier to bring back to life. Star Wars leaned on this a lot, especially in episodes IV and V. When R2D2 got shot in the battle of Yavin IV, right before Luke blew up the Death Star, I just about died. And yet, they brought him back easily enough for the throne room scene because he’s a robot–all they had to say was “we’ll fix him up” and you knew that everything would be better.

So yeah, droids. I haven’t done much with droids yet in my own writing, mostly because I’m a bit conflicted in my thoughts about the upper limits of AI (which I explored somewhat in Genesis Earth). Most of my robots are actually cyborgs, and that’s something completely different. Still, I can see myself playing with this trope at some point in the future, probably when/if I introduce some aliens or start a new series.

C is for Cryo

I think every science fiction writer has a cryo (aka “human popsicle“) story sitting around somewhere, even if it’s just in the back of their head. It’s one of those tropes that keeps coming back, just like the alien invasion, the robot apocalypse, and the Adam and Eve plot.

The basic concept is pretty simple, even if the technology is a bit more complex: a human or animal undergoes rapid freezing in order to put themselves into stasis for an extended period of time. Months, years, or even centuries later, someone thaws and resuscitates them so that they wake up in a completely different time and place.

There are a lot of good reasons why going into cryo makes sense in a science fiction universe. One of the more common ones is that the characters are colonists on a mission to an alien star, and their spaceship doesn’t have a faster-than-light drive. Rather than go through all the trouble of building a generation ship, the designers instead built a series of cryo chambers to put the colonists into stasis for an extended period of time. It might take centuries or millennia for the ship to reach its destination, but when it does, the colonists wake up as if it’s just been a long, dreamless night.

In The Worthing Saga, Orson Scott Card has a somewhat unusual rationale behind the prevalence of cryo in his universe (though they call it “hot sleep,” and it’s induced by a drug called soma). Only the rich can afford the technology, and the imperial overlords very carefully regulate the use of it so that there’s a clear hierarchy based on who goes under for the longest amount at a time. It’s a way for the citizens to achieve a simulated form of immortality, by skipping five or ten years every year or two of their lives.

In the Halo video game series, the UNSC uses cryo as a way to preserve their greatest military assets, the Spartans, for the times when they’re needed. The first game in the series starts when John-117, aka the Master Chief, is awakened just as the starship Pillar of Autumn crash lands on a mysterious alien structure. Like something from an old Norse legend, the third game ends when the Master Chief seals himself into the cryo chamber of a derelict starship, telling the AI Cortana “wake me when you need me.” (highlight to view spoilers).

So why are cryo stories so prevalent in science fiction? For one thing, they’ve been floating around in our cultural subconscious a lot longer than the genre has been in existence–just think of Sleeping Beauty or Rip Van Winkle. For another thing, the science is not that far-fetched. Certain animals can be revived after extended periods of frozen stasis, and according to the New York Times, it’s happened at least once with a human being. Science fiction has a long history of turning fiction into fact (for example, Arthur C. Clarke and communication satellites), so perhaps it’s only a matter of time before human cryotech becomes a reality.

I’m definitely a fan of this trope in my own writing. Genesis Earth has a chapter with a rather horrific cryothaw scene, which I later spun off into a short piece titled “From the Ice Incarnate.” I haven’t played with it much in my latest books, but in Heart of the Nebula which I hope to publish later this year, the cryotech plays a very important role in the plot. And if I ever write a prequel to my Gaia Nova series showing how that universe got started, it will feature a cryo colonization story. The main premise of that series is that a group of human colonists fled 21st century Earth and went into cryo to colonize a distant corner of the galaxy, but when they woke up, they couldn’t find Earth anymore, so it became something of an ancient holy legend (which is a major driver for Desert Stars).
