The Sevateem were the degenerated remnant of the original expedition's survey team. Their development and behaviour were influenced by Xoanon as part of its experiments to contrast physical and intuitive development with mental and psychic development. They lived in a concentrated environment, afraid to travel beyond its borders for fear of phantoms that, in actuality, were projections of Xoanon's psyche. Banishment was one form of punishment. The tribe also kept a pit full of Horda used for executions.
