This identity crisis drama is pretty weak. If you wanted the readers to think less of the main character and this story then mission accomplished I guess.
so is our BZ like a combined being that is the reincarnation of some terrifying souk evolvers.......like at some point after they died their souls combined and were born again into BZ? that's my only theory unless somehow the Sky Emperor is the same person as Sirius
what if the guy that with air manipulation was the true reincarnation of the sky emperor, but when BZ absorbed his records, he also absorbed the reincarnation?
