So this has been bugging me for a while... When Rashek took the power of Preservation at the WoA, wouldn't he have lost his body like Vin and Sazed? My understanding was that the process of apotheosis basically vaporized one's body.
I suppose he could've recreated it, but that always seemed like an unsatisfactory explanation, IMHO... Creating humans required the combined effort of Preservation and Ruin, and I don't see Rashek asking Ruin for help creating a new body =P
