That cheeky stat block on the torn cover is chef's kiss and I smiled like an idiot at the idea. I promise I'll wait a while before I steal it!
Praise aplenty for the prose, inside and outside, and of a timeless kind I found them to be.
Forsooth.
In any case I have to start off by echoing other commenters - this is brevity done with style and confidence. I've said in this jam before that I thought folks were doing a lot with a little and this has got to be sub 1k words by a certain margin!
And once again all of the interior, playable text, is basically in character? Wow. Every bit a flavorful piece for the GM to prepare from and the kind of spark-table style game design that I'd like to try a whack at myself.
Bravo.
If I had to dig up a nitpick and I mean really dig, this seems particularly system agnostic in all ways except for that Water Weird. Awesome either way!
