Great to see a jam open to all sorts of ttrpg systems! And there can never be enough pamphlet/short format ttrpg jams. Ryan, your Lumen games look great!
I'll be submitting a Mothership RPG one-shot. I'm planning for it to be within the same setting as my Themed Horror Jam #7 submission, and my forthcoming submission to the Follow the Convoy Jam.
Alien creatures, space-religion zealots, Gothic horror setting on a Forever-Rain planet. Excited to start putting it together, :D
