Okay, though I should clear up some things up. If your char has debilitating genetic mutations, then they would still have them and look the same after waking up. Authors do not die when becoming Authors/immortals or have a second life in the past. They are just transported to the past as they are and wake up with their new traits. There is no getting a new body, and you can still die, like being shot with an arrow to the head. So, while, they cannot die naturally, still have to deal with the mortality of their governance if there is a uprising and they get killed by rebels.
