It is the time of the Great Crusade, a time of legend and myth. The Empress of Mankind has sent her greatest generals, her Primarchs, out into the stars to unify humanity under one banner.

Now possessing the body of the only male Primarch, will he be able to change the grim future with his knowledge of the setting or will the galaxy burn?

READ THIS: this is a quest that I'm running on fiction live, so if you notice anything weird its because it is written not as a story but in a quest format. If you want to vote on the direction of the story, head over to fiction live and find it there.
