Long established in the background as being directly responsible for the shape the galaxy is in in the 41st millennium, it is the subject of the Horus Heresy series of novels and audio books, by various authors. The God-Emperor was permanently injured in a lethal duel with their leader, the Primarch Horus (his son, in a way), to the point that he is only kept alive by an extremely complex life support device known as the Golden Throne. In the Backstory of the Warhammer 40,000 universe is humanity's era of hope, only just starting to dawn after the long and terrible Dark Age, before it is brought to an end by the Horus Heresy, wherein fully half of the best warriors the human race had to offer turned to worshipping dark gods and nearly wiped out the other half.
