Mordian is an Imperial Hive World in the Segmentum Obscurus that is the homeworld of the Imperial Guard's Mordian Iron Guard regiments. Mordian also once came under a great assault by the Forces of Chaos that was defeated only through the extraordinary discipline and valour of the Iron Guard in one of the Imperium's finest moments. Mordian is a Hive World with tidally locked rotation on its axis, leaving one side of the planet locked in eternal night while the other side is cooked by the Mordian sun. Ruled by a totalitarian regime that controls the planet's meager supplies, Mordian is defended by the elite Iron Guard - a highly disciplined army wearing ornate uniforms. Many of their enemies have underestimated these ranks of colorfully-uniformed troops, only to find out that they were tough and uncompromising soldiers.
Nuceria was the brutal and unloved homeworld of the World Eaters' Primarch Angron and also the planet where he was discovered by the Emperor of Mankind during the early days of the Great Crusade in the late 30th Millennium. In ancient days it was classified by the Imperium of Man as a highly technologically advanced Civilised World of the Ultima Segmentum, though current Imperial historical records do not generally state its name or its location, which were expunged from all official Imperial records following the events of the Horus Heresy. This is most likely the result of an Edict of Obliteration that was carried out to remove any trace of the world that spawned the fearful Daemon Primarch Angron. Following its scouring by the World Eaters Traitor Legion during the Horus Heresy, it is now a Dead World, wiped clean of all life. 153554b96e
