The Weylan are born infertile. They can’t have children the natural way. The Albion designed them that way on purpose, after losing too many promising Weylan to the rigors of childbirth. The problem was the wings. Birds grow up inside an egg and then break out. Their wings are fully formed and ready to work at that time. But humans give birth by pushing their child through a thin tunnel and out in to the air. The birth process almost always broke the wings, and sometimes tore them apart inside the mother. So the Albion made their best creation infertile to keep them from dying out, and then built a massive collection of cloning chambers to grow new ones. Most of those died when the Ennead destroyed Arkadia, but the Weylan saved a relative few. They were the only way the Weylan could procreate for the next two thousand years, and they were too few to generate anything that might be termed a population boom.
Hyperphysicists sometimes call Alpha Centauri a quadrinary star system. There is the primary Binary System composed of Cen A and Cen B that most people think of as Alpha Cenaturi. Then there is Cen C, often times called Proxima Centauri due to its proximity to Earth. And there is Sol. Earth’s own sun. Earth, Proxima Centauri, and the Alpha Centauri Binary System are linked through hyperspace in ways that few other stars are. That is why starships can travel from Earth to Alpha Centauri so much faster than from Earth to any other star. But the link to all of those other stars flows through Alpha Centauri. That is what makes it our gateway to the stars.
Rhiannon is one of the younger Weylan out there. She was not alive during the last great war. She did not see the Ennead destroy her homeworld. She did not kill the Ennead in response. She didn’t even live through most of the two millennia that followed. She wasn’t born until after the Peloran made Contact with us, in fact. Hers is a small generation, as all Weylan generations are, but they were raised in an autumn of peace. She grew up knowing it would be her job to fight the next great war that came along. And they expected it to come along soon. I envied her that, once I understood. At least she wasn’t surprised by all the shock and violence that heralded The War. And she envied me, once she understood what growing up in a time of peace and innocence could be like. It’s amazing how life works. What we can miss when we meet someone who lived a different life.
The Weylan spent the two millennia following the last great war rebuilding their civilization. Arkadia was a binary system, and the other star had a gas torus in orbit thick enough breathe in. There is some speculation that it was created via an Albion experiment, but hard information was lost when the primary Arkadian planet was destroyed. The Weylan moved into the gas torus, and towed pieces of the old planet over to act as small planetoids they could live on. They’ve lived in the seemingly endless skies of Arkadia ever since. They’re wings make them uniquely adapted to the environment, and under normal circumstances they probably would have multiplied like rabbits in their new world. But that is one thing the Weylan can’t do. Have babies. They are born infertile.
I have been writing or developing the Jack of Harts universe for years. It started with the characters, and then I began to flesh out the universe around them. What kind of universe would forge someone like the people I wanted to write? I realized early on that it wasn’t going to be any form of a dystopia. I grew up on Star Trek, Star Wars, Buck Rogers, and Battlestar Galactica, where the men are men, the women are women, and the furry little creatures from Alpha Centauri are furry little creatures from Alpha Centauri. Sorry for those who missed that. There’s a bit of a sliding joke in that line. 😉
Most of those had pretty loose rules when it came to hyperspace. Otherwise known as Plot Rules. Hyperspace does whatever the plot requires. I like the simplicity of that, but I’m a bit of a wargamer. I like rules.
So as I have developed Jack of Harts, I’ve been slowly putting together rules for how hyperspace works. They barely showed up at all in my first book, Forge of War. Though that book took place entirely in the Earth and Alpha Centauri star systems. And for story purposes (ahem…Plot Rules) I really didn’t need to explain it. There’s a reason for that, and it involves why Alpha Centauri is Earth’s gateway to the stars. But it wasn’t important to the story, so I didn’t touch on it. The action started on Earth, went to Alpha Centauri, and stayed there.
My Wolfenheim Rising and Angel Flight stories required a bit more theory of hyperspace to be remarked on though. I still kept it rather light, as I don’t want to bog readers down with infodumps, but there is one thing I did note. It’s called a Hyperspace Run. Every star has them. These are the rainbow rivers of light I describe. They reach out to other stars and create the runs that most ships use to travel between the stars. Note the “most” in there. Ships can travel in the deep dark, away from the runs. They just go slower.
I will note that I picked the rainbow rivers of light motif for the gravitic links between stars, the “highways” we use to travel, from old Norse mythology. The gods of Asgard used a rainbow highway to travel between the realms. You may have seen an example of that idea in recent movies that sport a certain Norse god and his manipulative brother in them. 😉
The point is that I wanted these links to be as realistic as possible for speculative fiction, while also being fun to play with. I am a wargamer, after all. So I came up with some complex rules for how far stars can reach, and how fast their runs are based on how hot or large the star is. I have entire spreadsheets detailing this, along with real universe 3D coordinate maps of where every major colony is. And the real space, real star system data, we use to go between them. Maps of normalspace and hyperspace that I use to plot the time and range of each movement in the Wolfenheim and Angel stories.
Serenity orbits the real star known as Beta Hydri.
Sunnydale, where the fleets assemble to assault the Hyades Cluster, orbits the star called Psi Tauri.
And Bosphorus, the doorway to the Pleiades Cluster and The Gateway, is the star we call 16 Tauri or Celaeno.
Every single colony I’ve mentioned is noted in my files, and almost every single one has a real star it is associated with. A real place we have observed with our own eyes and telescopes. We know where they are, we know what kind of stars they are, and sometimes we even know if there are planets around them.
So if you give me a real star, I can tell you if we have colonized it. And if you give me two stars, I can tell you what stars you have to travel through to get from one to the other. Because the information is in my notes. I just try to keep that out of the stories as much as possible. Infodumps. Not everybody likes them.
But I rather enjoy having it all sitting in the background, ready to trot out at a moment’s notice. Who knows? Maybe someone wants to take the midnight train to Rigel one day? I can tell them how. Though the Plot Rules might make the exact pathway a little vague. 😉
