Exorcists

The Exorcists are a highly unusual Loyalist Chapter of Space Marines created during the 13th Founding, the so-called “Dark Founding” which occurred sometime between the 35th and 36th Millennia, before the start of the Age of Apostasy. The true identity of their progenitors are known only to the highest-ranking members of the Ordo Malleus, and details of their creation have been placed under Inquisitorial seal, though it is widely accepted that they were raised from the genetic lineage of Rogal Dorn, and share many of the stoic traits of other Imperial Fists successors. The Exorcists were founded as part of a highly-classified Imperial experiment to create Space Marines who were unusually resistant to Daemonic possession and Chaos corruption.
