Named for the madman/religious prophet that founded the tightly-knit rim colony of “Bohan” along the only narrow and airless strip of barely habitable land available on the surface, Elos Thu’Ban is a tidelocked world (one side bakes, the other side freezes). The few colonists who follow Thu’Ban and who have chosen to settle in the nearly inhospitable moderate belt between the more extreme sides, make up the body of a very secretive and reclusive religious sect that keeps to itself and maintains an almost aggressive stance against letting visitors anywhere near the planetoid. A cloud of relatively stable rock and a few errant chunks of cometary ice that have been snared by the pull of the little planetoid keep an additional sense of mystery and privacy that tends to scare off most of the colony’s would-be visitors before they even get within visual range. It’s not the kind of rock you’d find on any map, and those who dare to enter the rock field on an approach vector to Elos Thu’Ban are sternly urged at range to turn away before the colony’s array of interorbital cannons comes online.

The rim colony of Bohan is enormous– at close to 12,000 KM in length, it rings the entire planetoid as a single contiguous city uniformly 2.8 kilometers in width. Great walls of blasted metaceramics hundreds of feet in height contain the sprawl on either side for the entire length, and more than half of the visible towers and spires that peek over the edge are studded with vicious turret-mounted cannons. Power is partly solar, partly void mechanics, but mostly geothermal, as the core of the rock is still active, if only barely so. On the whole, the followers of Thu’Ban have worked hard to make their operation entirely self sufficient, so supply transports visiting in-system are few and almost exclusively staffed by cult members. Little is known about the populace due to their isolation, but estimates place the population of Bohan at just over 200,000. In the rare circumstances when they export materials, they trade primarily in gold, opal, and other precious metals and stones, and almost always send a ship out of the field to make the exchange instead of letting any outsiders in.
