Profane Ritual, Expert (Patreon)

Experts- this is the Profane Ritual (35x35), a great spot for spooky bad guys to do bad stuff in the woods. Lend out this circle to your evil organization of the week: cultists, druids, demihumans, draculas, frankensteins, lizard men, etc. and give them a vaguely nefarious plot to accomplish here: end the world, summon a worse bad guy, gain power beyond comprehension, or empower their deity/patron/master. And just like that, that's next week's session and maybe the next one too if your party seems drawn in and a few baddies get away.
