Pitch Black Dreams: (PBD Book 1) (Walpurgisnacht Series)

Whilst trampling countless foes during the climax of a great inter-dimensional conflict, a certain cosmic being is reminded of the world and the people that he'd had to leave behind before he could get where he now stood. He is made aware of certain facts and fates that befell those people and that world while he was away. He is given the choice of winning the war or going back to fix things. He chooses to go back.

Now having returned to his world and the body of his youth, a certain young man will save his friends and try to live as normal a life as possible, for someone who'd used to swallow entire worlds.
