Whoops, made a comments before realizing you'd basically already included what I was talking about. Anyways, it looks good. Would be nice to flesh out a world and make an NPC that is supposed to be some sort of eternal watcher of something. One thing I would think though, bonuses to Knowledge (History). Either in "Been There, Done That". There is a chance that if they are an immortal that they could have been there for a historical event.
