Carnival of the Apocalypse - Mists of Ravenloft
Rosavaldt & Thornbolt Durst
Rose and her younger brother Thorn are ghosts who haunt a mysterious row house in the village of Barovia. It has been revealed that the pair were locked away in their bedroom and left to starve by their own parents, likely centuries ago.
They have beseeched the party to rid the house of the “monster” which haunts it and also to find their missing baby brother Walter. The ghostly pair are bound to the room where they died and apparently can not leave.
