The Cognitae was a Chaos cult which took the form of an academy, run by its founder, Lilean Chase. According to Inquisitor Gideon Ravenor, the Cognitae's aim was to develop, "by means psychic, eugenic and noetic," a generation of individuals who would work to further the aims of Chaos in the Scarus Sector.
According to Criol Fowst, the Cognitae, or some version of it, had existed within the Imperium for millennia, as far back as before the Great Crusade. It also spawned several offshoots and imitators, some of which tried to recruit Fowst. He found some ideals in common with them, but ultimately rejected them in favor of his "true" calling, as a cultist in service to the Word Bearers.
