Monastery of the Distressed Body

The Monastery of the Distressed Body was a creepy monastery situated on a floating island in The Barrier Peaks which is now the Drakeguard Barrier Peaks Valley Office.
It was led by its grandmaster, and was home to many followers of his cult, along with various prisoners. The island that hosts it seems to have originally been a vessel designed by some very clever folks who know science stuff that nobody remaining on the island really understands. However, the cult have used some of this technology to remove the faces of the cult members while keeping them alive, with the faces used to make an awesome but creepy cloak for the grandmaster.
The grandmaster also used technology on the island to conduct brain swaps and brain extractions. The members of the expedition of Qwalish (but not Qwalish himself) were at some point removed from their bodies and left as brains alone controlling various systems of the island.
MCVFD defeated the grandmaster and seized control of the island on behalf of the Drakeguard. They left a Drakeguard operative in charge of controlling and studying the technology while moving on to other priorities.
