Accatran is a loyalist forge world with Machine Cult enclaves in the Five Hundred Worlds of Ultramar; home of Legio Destructor and creator, on its thrall world of Anvari, of Legio Oberon. It mustered the “Taghmata Xerxes” at Calth on Horus’s orders; at the Betrayal at Ithraca (007.M31) Xerxes’s army was annihilated — the magi detonated a manufactorum reactor, incinerating everything within half a kilometre and destroying 23 city blocks, but inflicting terrible losses on the traitors.
