Warhammer 40K: Dark Age

In this dark world there is no hope, luck, safety, and poor freedom. There are only wars and endless wars. Hateful aliens and heretics seek to destroy our great empire. We, the great Emperor, led humanity to a brief moment of glory. Horus, a cursed and sinful name, the traitor launched a rebellion that nearly destroyed the empire. The angel fell, the Emperor was seriously wounded, and the Empire was ruled by ignorance. Hope for humanity dimmed. Cadian fell, the Great Rift was born, and half the empire fell. Roboute Guilliman, son of God, leader of the Ultramarines Chapter, ruler of Ultramar and regent of the Empire. He longs for the empire to become strong again! The subspace is not peaceful either, that unimaginably weird realm is like a butterfly effect, and various gods are spying on certain things.
