I wonder if this has anything to do with the Kwalishar Ruins dungeon that Tim Kask worked on. Has there been any word from him about this, considering Kwalish is his character?
Heya, name's Lyka, been alternatingly playing and DMing over the last 15 years now. While I'm only really used to the 3rd and 5th editions, my favourite settings to work with are Spelljammer and Planescape.
