Souls of the reincarnated are from any time starting before the ancient through after the most futuristic within the multiverse. They know and remember what they knew in the life they came from. Whatever world they came from they must live within the laws of spacetime that exist in the multiverse they have been brought to. Many remember that something called combustion engines and electronics existed in their world and are disappointed to find that they have little use in this multiverse. What they do find to take the place of the remembered wonders is that magic with the storage, flow, amplification, and use thereof exceeds the fantasies they imagined.
