I am reachable on bluesky or Discord as SimiOfDoom, or via email as simone.bannach[at]protonmail.com (also thank you for making me aware of the fact that itch does not have a messaging option)
You are right, that it is a (sort of) Solomonic Seal, like the Ars Goetia uses, but I made that myself to be my TTRPG-stuff Logo! It spells my username in a fancy way, haha.
Oh, that's really cool! I'm interested in the Ars Goetia. I was thinking of featuring it in my next RPG project. Anyway! I'll write you with my question soon.
