Iron Warriors helped other traitor legions destroying Imperium's strongholds. When Horus got killed, they retreated (with organisation, unlike other legions who simply ran away) to Mendregad in the Eye of Terror; it would be their new homeworld.
They also made a trap for the Imperial Fists, a world totally converted into a stronghold, but without any purpose or objetive into its core. Imperial Fists offloaded there, and all were killed. This victory made of Perturabo, Iron Warriors' Primarch, a Demon Prince.
