What happens if the body dies while a possessor is in residence?
This is rather tricky and has several permutations. If the possessor has a body to return to (the usual case), they simply bounce back to it, but take Mind Hits equal to the “excess” damage it took to kill the body being possessed. If the singer has no body to go back to, they are treated as if they had just experienced death (Trauma for celestials, and death for humans). Of course, Malakim, Kyriotates, and Shedim have their own special rules involving vessel death. The POSSESSEE, on the other hand, is in a bizarre state. Unless the GM wants to do something fun, humans die and go their final reward (whatever it would normally be). Celestials, due to their abscence, is spared Trauma because they weren’t in residence at the time. They feel a distant loss, but that’s the extent of it.
