I have noticed some have posted and mentioned something about lingering souls wandering the area. Just to be clear for future interactions, the castle grounds will be free of roaming souls starting the next IC day, as Par'Sath is now proceeding to spend the entire night guiding these lost spirits to the afterlife. Obviously, that doesn't include souls trapped within artifacts or on characters.

Oh, and feel free to interact with him if your character has a fancy of speaking with a Reaper. Just call out to him and he'll come to you.
