Herodor

A desolate world, located in the Sabbat Worlds, Herodor was the planet where the Imperial Saint Sabbat was believed to have been reincarnated, providing a major morale boost to the forces of the Imperial Sabbat Worlds Crusade. It was attacked by the forces of Chaos, mostly members of the Blood Pact but also with the aid of nine Champions of that foul creed. Eventually, Imperial forces including the Tanith First Imperial Guard Regiment of Gaunt's Ghosts fame aided in crushing the Chaos invasion.
