Rage against Creation
Home plane to House Usher, by which is is viciously and brutally overseen. By Demonic right, owned by Iszitst, who commands his followers there from The Underneath. The plane itself seems to be backwards, savage, and outright cruel most of the time, despite the outward beauty and grace of the people living there.
Good exists, by Iszitst’s will, only to provide a frame of reference by which evil can exist and flourish. The innocent and the weak are tolerated by Iszitst only as a means of attaching to those who display more heroic or revolutionary characteristics, and using them as leverage, or even just to kill them and send a message.
In this way, all good is soon snuffed out, and the righteous are left to suffer for as long as they can take it, or turn to the easy life of evil and violence that will be richly rewarded.
