Coming at this a bit late, but I was revisiting the podcast and actually sitting down to listen, and as one of the writers, I'd like to note that while it's not explicitly stated, we never put any limitations on what characters could play as, and frankly, I'm entirely enamoured with Wolf the Cat.

Thanks! We reached that conclusion when we didn't see any evidence of sentient nonhumans aside from the monsters through the character creation portion, but it's a good note for anyone who wants to play!
