What energy is there in the warp that Kuvara needs, I am guessing it is not divine qi, or the tyrant god wouldn't buy any from us, is it qi? Something else? Asking since I wonder if a cultivator can basically draw infinite energy from there, if not for all the demons and evil gods, we already kind of saw the warp when a demon was summoned, and Kuvara does need that energy, so I wondered if the emperor knows something.
Are there any benefits to reincarnation, does it strengthen psychic power, do skills somewhat carry over, is there any difference between it and being born normally?
Asking because I know Eldar and shamans used it as a method of immortality, where information carried over between reincarnations, so I wonder if the average Keku get anything out of it, despite not being psykers and thus capable of surviving death relatively intact.
