The Hall of the Brush is where all the Basement's religions are all neatly placed. It is near to Barter Hall.
- Candle Monks: believe that they are far too dependent on the Tree and thus "make their own light". They wear robes.
- Ears of the Brush
- Spelling Guild: people who literally take words seriously.
- Doomsayers' Guild: straightforwardly named. (Once called Doomsayer's Guild.)
- Ludwigites: a religion founded on Ludwig and the stories about him.
