Wans transmigrated into Warhammer, and fate gave him no time to grow stronger. He was already caught up in the Horus Heresy, amid mountains of corpses at a pivotal moment in history. In ten minutes, an orbital bombardment would blanket the entire battlefield. Virus bombs would turn the land into a rotting graveyard. As an ordinary mortal, he had no chance of surviving the Horus Heresy.
But just as death came for him, Wans awakened a special ability. If he killed a Space Marine, he could wear power armor and infiltrate enemy ranks as a "brother." If he killed a Primarch's bodyguard, he could stand at a Primarch's side, becoming the most dangerous observer in history.
So... what if he killed a Primarch?
Death was no longer just an ending. It became Wans's way of evolving, and so did the world.
In one world, Tzeentch joined with the Emperor and bore him nine illegitimate children, giving rise to the most chaotic grand birthday celebration of all.
In another world, Chaos drew a winning hand, the Imperium was driven back until only the Solar System remained, and Terra became the last lonely grave.
In yet another world, Wans had never existed. The story of the universe unfolded just as it always had, slowly descending into despair.
Wans had only this to say: "Sit tight, Emperor. Watch me work!"
