Neat, love the idea of being able to do this on the go. One suggestion, having done an alphabet-to-generate-stuff game, it may be worth reusing letters for some things like contents. As it stands now, most people will rarely if ever run into a Dragon since there are few words that end in Q and that's the only time you have one as an encounter. Still, always a fan of diceless way to play on the go. Great stuff!
Amusingly, when I read this, the book I had one of my bookmarks in had several words ending with a q on that page! (Arabic names.)
It's possible I deliberately chose dragon and q for that reason, but it's a while since I wrote this. There was quite a gap between creation and publication. But that's definitely worth taking into consideration!
