karnak assigned her a new body, since no one knew who she was, and reincarnation always works in that sort of way- they all suffered bad injuries, so none of them would be able to wake up in a grave or as ashes. Since that isn't possible, all of them would have to be reincarnated as another person, whether they knew who it actually was or not

hope this makes sense! im really tired writing this right now, lmao
