I've recently added a new 'canon' book to the game called the "Book of Penances". It's a sister book to the Erra Pater.
It brings to mind that we have several topics on TI that could use more fleshing out. Does anyone have any ideas for what kind of books might be great additions to the game? Let me know, and I'll consider dusting off my writing equipment... or farming it out to players on a commission basis... Thanks!
