The Emperor of Mankind

The Emperor of Mankind is a character from the Warhammer 40K universe. He is as the name suggests the Emperor of Mankind.

History
The Emperor united mankind under the Imperium of Man, a secular empire. His sons, The Primarchs helped him lead humanity to a golden age. Unfortunately one of his sons Horus started a civil war and wounded the emperor forcing him to sit on the Golden Throne which kept him alive. After he was out on this throne humanity began to worship him as a god which is the opposite of his secular empire. This is the source of the copious amount of grimdark in a Warhammer 40k.
