The Demon Stones (Swords & Wizardry)

When enormous stones fall from the night sky, a deadly curse settles over the village of Gravencross in the Hoarwych Valley. The adventurers must investigate the impact sites, confront the supernatural forces surrounding the stones, and help the villagers exorcise them. This fantasy adventure is designed for 3–5 characters of levels 4–5 and can be placed into an existing campaign. Gravencross is detailed as a standalone base, while new threats include Ostopheles, lesser basalt elementals, and fyrs, along with the new god Basaltor.
