In the far future, there is only war. A darkness has descended upon humanity throughout the galaxy. Now there is only conflict, pestilence and death. For the average human, each day has become a struggle to survive full of servitude, pain and suffering. Scientific progress has halted and much of what was previously known has been lost.

In the vastness of the corrupted, militaristic Human Empire lies a world called Uisneach. It orbits a yellow star and has been inhabited by humans for many thousands of years. It’s atmosphere is toxic. Nobody remembers if it was always that way or if it was the humans who caused it. The world contains two hive cities, each containing many billions of people. One of them is called Xenos. It is the size of a small continent and extends upwards in layers towards the sky.

Each layer is filled by a different economic class. Near the bottom layers is the janitorial sector. To go lower is to go where there is no law, no order. There is no return. To go higher is to live a few years longer and possibly not have to watch your children die. Many fall down the rungs of layers but few rise.

The janitorial layer contains many of hundreds of millions of people. It has its own culture, heritage and language. Many here, scoff at the idea that they are part of some galactic empire or even that they exist on something called a planet that orbits a star. Light from their sun hasn’t reached this deep in a very long time.

One of their favorite customs is “Wheelchair Wars”. It’s one that this layer has that makes it renowned throughout the rest of the city. Nobody is sure why or how it has started, but now events are held in large stadia and broadcast throughout the world.

There are ten tribes, each one covering a large area. They select their best players, who must have a physical disability requiring wheelchair use for competition. They are given modified wheelchairs, now more like tanks, with which to fight to the death. Very few are expected to survive. Any that do and the eventual winner can look forward to serving as dreadnought commanders in the Imperial Army.
