This planet is most known for being entirely devoted to the production of Land Raiders during the Great Crusade, and was set to this purpose due to the huge demand of the vehicles among Imperial forces. It created the first Land Raider, the Land Raider Proteus. In time of Horus Heresy planer was captured by the Dark Mechanicus' renegade Tech-Priests and the supply of Land Raiders to Imperium forces was stopped. It is unknown whether Anvilus Nine was recaptured by the Imperium's armies or not.
