Just in case you were wondering, this is the arena description:
Painborne Cathedral - A monstrous cathedral, approximately 20 stories from base to apex. The inside is an interweaving mixture of leering passageways and enormous chambers. The center of the church is a tremendous stone room filled with marble pews, and a ten story pipe organ taking up the entire back wall. Dilapidated, mildewed, rotten, abandoned, and lit with a sickly green glow.
