The Daemonculaba was the name given to the individuals used in the attempt to create new Chaos Space Marines, making use of the uncorrupted gene-seed stolen from the Imperial Fists' repository on the world of Hydra Cordatus. It was a project undertaken by the Iron Warriors Traitor Legion, and overseen by the Warsmith Honsou. It took place deep within the dungeons of Khalan-Ghol, Honsou's fortress on the Daemon World of Medrengard. The project was destroyed through the efforts of Captain Uriel Ventris of the Ultramarines Chapter and his small band of allies.
