I really liked this little supplement! It presents an unnerving puzzle, sort of an escape room/point-and-click feel as your (presumably) mages investigate the magical mishap. While on its own it doesn't give you a ton of explanation, it is clearly meant for the storyteller to build off of and use to develop a compelling story. I put it at 4 stars because while it's definitely compelling and evocative, and really nicely-written, I did not enjoy the Warm Rat ;-;  a part of me just wanted a little more, something extra to spark the storyteller's imagination. And that may just be a me thing!

(I'm new to rating, so hopefully this isn't an Amazon situation where any rating below a 5 is a downvote.)

The opening line slaps, by the way.
