Nicomedua is a world of the Imperium.
A tributary planet of the Adeptus Mechanicus, during the formation of the Great Rift the planet's ruling Tech-Priests were corrupted by the Dark Mechanicum. War quickly broke out on Nicomedua, and after years of fighting by the Imperial Guard stalemate endured. A Titan Battlegroup from the Legio Metalica led by the Imperator Titan Cassus Belli was able to finally turn the tide.
