yea cause arisths have to get the technology at some point so they didnt get it from their parents, and neither did tobias from elfangor
i think that based on the morphing rules it should die, but if you think stuff like food morphs with them in some way then who knows, i think touqs probably right that it would die in zspace
sidebar, i was just thinking about why the yeerk can morph with the host. maybe the brain is pushed entirely whole into zspace, which would make sense because while the rest of the body could be broken up and reassembled functional, the brain remains functional and connected while in morph so it should stay whole, and if the yeerk is flattened against it, it would be transported whole too
