Kyriss the Perverse

Kyriss the Perverse is a Keeper of Secrets of Slaanesh who, together with Ka’Bandha, orchestrated the Battle of Signus Prime against the Blood Angels. He ruled from Signus Prime in the palace “Cathedral of the Mark”. Erebus, Lorgar and Kyriss wished to turn Sanguinius to Chaos; after Ka’Bandha’s banishment Kyriss offered Sanguinius a bargain, but the apothecary Meros accepted the “gift” in place of the primarch, and an enraged Sanguinius beheaded the daemon.
