Khrave

The Khrave are a dangerous species of psychically-gifted xenos that act like slavers and which have been plagueing the human race since the earliest days of the Great Crusade, and are believed to have risen during the Age of Strife. Little is known of the physical appearence of these aliens, as all accounts of their encounter emphasize on the Khrave’s psychic abilities and their dreadful technology. The Khrave are psychic leeches, feeding on the minds and souls of subjugated human worlds they infiltrate and subdue. The Khrave also seem to possess some kind of natural affinity with the Warp as they preferred weapons are so-called warp-glamours, blades forged from the solidified matter of the Immaterium, easily able to cleave through Power Armour. The oldest and strongest Khrave encountered are said to have been able to rival a Primarch in bulk, although these exemplars are thankfully rare.
