Thank you so much! I get so happy when I read how much the game is resonating with people, it's incredibly energizing. And I'm also glad my references really seem to be coming across. :)
Re: creatures! I'm currently working on an Online Bestiary and I'll likely post all the creatures there. It's a WIP atm, but I made sure to include a Monster Maker from the get-go, so GMs can cook up their own homebrew monsters.
