Radical Atavists (the ones who reject sapience) are further divided into two factions: the Atheists and the Misotheists. The Atheists are straightforward: sentience is a random fluke of the blind purposeless process of evolution, one which they find undesirable and wish to correct.

The Misotheists are a much more interesting lot. They believe The Light is evil, and that it cursed them with sapience. Many Misotheist Atavists seek to kill The Light. The means by which they try to accomplish this goal are legion, and may or may not involve spiky hair, giant swords and long-winded speeches about the power of friendship.
