Sure I'll put that together this evening. I suspect this is how I'll group the areas:
Main path: Rainy Hall, Archives, Entrance Hall, Refinery, Cellar Archives, Archive Tunnels, Back Hall, Prison, Cistern Entrance, Sewer, Nave, Chancel, Inner Sanctum, Orb Chamber

Chapter 1: Rainy Hall, Entrance Hall, Archives, Laboratory, Wine Cellar
Chapter 2: Refinery, Cellar Archives, Archive Tunnels
Chapter 2: Back Hall, Guest Room, Study, Storage, Machine Room
Chapter 3: Prison, Cistern Entrance, Cistern, Morgue, Sewer
Chapter 4: Nave, Cells, Choir, Transept, Chancel, Inner Sanctum, Orb Chamber
