While I was asking some questions in general chat about death in the Curse of Strahd adventure, @Derpy brought up an interesting point (that might contain loose spoilers).
Correct me if I am wrong, but I think the rulebook/guide itself makes it clear that
even souls are trapped in the realm. If you die there, your soul can't reach the afterlife. I think there is even a 24 hours rule somewhere in the book: resurrection after 24 hours = free madness points for realizing you cannot even really die.
Is this true, and if so, where in the campaign guide does it say so?
