Mordian

The Mordian day is the same as their year, and as such half of the planet is bathed in perpetual darkness and the other half burnt to a sinder by the glaring sun. This makes it quite a miserable place. The planet's lack of rotation prevents any strong winds and as such the atmosphere is think and dark. The millions of inhabitants live in vast hive cities where all resources are controlled and distributed by the state. There is much discontent among the people, and the Mordian Iron Guard spend much of their time keeping the populace down.

In a massive Chaos conspiracy, a group of Chaos cultists met under the busy streets of the Mordian capitol of Vanandra. There they cast a spell, taking the blood of many, most likely innocent, Mordians. The spell brought ships full of Chaos Space Marines and summoned Daemons to Mordia. They rampaged across the planet and eventually managed to force the Iron Guard back to the capitol. Here the Guard put up one last defence, gradually falling back and back until they had to take bunker in the Capitol building. They had used dangerous tactics that most armies would have refused to use, mainly because their men would not stand their ground. The Iron Guard, living up their name, stood against all manner of daemons and their position was hopeless. In orbit above Mordia, the planets psykers had at last succeeded in breaking the Chaos spell, and gradually the Daemons faded from the planet. This disappearance scared the remnants of the Chaos attackers and the Iron Guard took the opportunity to rout the enemy and dispel them from the planet. Through their discipline the Iron Guard had held back the forces of Chaos long enough for Imperial psykers to break the spell, and ensure that Mordia would remain in the hands of the Imperium.
