Oh, that's a good question. I'm still working on making a single creator kit for Breathless, Nomadic, Renegades, Stoneburner, and TotBS, but it's taking more time than I'd like.
Technically, the whole game is open licensed, so if you want to make a hack of it, check out this website: https://farirpgs.com/burned-in-stones/license
As for a jam, that's definitely something I'm thinking about, even more so considering the Songs and Sagas Jam is now wrapped up.
