hahaha, no way do you put it in warhammer, although there are things more powerful than the gods of chaos such as the well of eternity, the gods of chaos are still multiversal entities, not to mention the dangers and lovecraftian-style entities that exist in warhammer (especially in the halo and ghoul stars) unless you have a very, and I say very high power, the protagonist would not survive (and that is without counting the possible assassination attempts, either due to alleged heresy or because of a noble wants, and that's without taking into account that the mechanicus will probably try to steal your technology)
