Reading through this went so fast; all of the rules felt like prose, they were so charming to behold (Gname and Prognouns really got me). The thematic elements and tone of the game are so clear that I feel like I could write a one-shot in it without any further prompting. The mechanic of glamour is a great addition (and clever use of the d12), that elegantly gives space for a bit of leniency but keeps things moving - and the tension increasing as time goes on!
It does look like there's an error underneath the description of Spelling, where it says you succeed on a 1, 3, 4, or 5, while I think it should just be a 1. And, though I may be biased by my own foray into Polymorph, the game feels light without any Edges for the Gnomes to choose. But overall, this was truly a delight to read, and seems like it would be a ton of fun (and a bundle of hijinks!) to play.
