Earth Body Borka is a cluster of several thou sand rocks linked together by a common atmosphere. It was once a single small planet, but was destroyed by extradimensional magic by the elves in the Unhuman War. The planet was a stronghold of orcs, goblins, and other evil humanoids, which the elves wiped out with the assistance of their gods. The method is unknown, since soon afterward the elven armada in Greyspace was eradicated through a systematic series of accidents and attacks. This was the only planet wiped out by elven attacks, and the event has not been repeated. Many of the orcs and other humanoids fled Borka on its destruction, fleeing to Oerth and into the deeper regions of space. Some remained, and these are rebuilding their cultures along planetary and racial lines. Most of the new construction is within the clustered asteroids themselves , not leaving outside clues to the elves that they are attempting to mass their forces. This secrecy, well-reasoned though it is, verges on the paranoid, and orc and goblin ships will attack strangers in order to preserve their secrecy. The orcs can also move their rocky homes slowly among the others, so that if an attack force does come, it will likely not be able to find the same rock as before .
