I'm wondering if there are any Discord servers or other places where people are talking about their progress for this jam. If not, I'd be happy to see people talk about what they're working on here.
Here are some pages at the front of Ash Trapped in Cracked Lips. Doesn't show a whole lot, but they're what I just worked on. It has it's own full system, but is meant to let other d20 systems (such as Cthork Borg) swap into the setting fairly easily.
