Arketh is the headquarters and primary base of power for the Companions of Roving Doom, an Agrikan fighting order with a reputation for violence and brutality. Shaped by the dogma promulgated by the clerics of the Order of the Pillar of Fire, the Companions see Arketh as a model for an ideal Agrikan society.
