I got this because I saw you talking on twitter and I LOVE it. The writing in particular is so evocative and the combat seems really spicy.
I have two small suggestions:
1. Any game that uses tags benefits from having table of contents or bookmarks in its PDF to make it easy to move between parts of the book when doing combat. Putting these in the appendix also works, just it would be nice to easily be able to look up what "overwhelming" does when it comes up during play if you forget.
2. Given the intense fantasy of the setting and premise some sample ideas for ops would be helpful to guide a new GM on picking some initial outings for their Brace.
Anyway. This is great. Thanks.
