In level 76 of the personal story, at “Descend into the ossuary’s lower chambers”, I was at the entrance of the lower chambers when Trahearne flew up into the air and fought from up there. I went ahead and left him, and finding the path too hard to solo, I went back. He died, and I am unable to revive him because he is floating. Here is a screenshot. I cannot continue the story without him being alive because he triggers an event.
