I hope the wording of this makes sense, it doesn't really even affect me directly but I'm curious to know: if an immortal character believes that it's been hundreds or thousands of years, how would they handle mortal characters who should be dead from their standpoint? Would they be able to see them for the event and be really confused as to why they're suddenly alive and young again or would they perceive them as ghosts/voices/something along that line? On that note, is it even possible to die of old age in the tower?
