My Hero, the Herald of Death

We reside in the Origin. Humanity's purpose is to construct worlds for the Eternum. Through our creativity, a world is created. Through love, the universes are consecrated. Through dreams, universes are refined. But some of those universes become too divided, too full of strife. Harry Potter, Star Wars, Warhammer, all these worlds have so many different interpretations that the universes are fractured. When a universe fractures, an individual with knowledge of it is chosen to preserve the timeline in their image, attaching the world to themselves. This story revolves around the chosen of MHA, the Herald of Death. (Art is most certainly not mine)
