Return to the Monolith (7e)

From the introduction: Untold years ago, worshipers of a foul toad-like being arrived in what is now Hungary. They raised up a stone monument to their god and performed terrible rites around it, with the vilest rites taking place on Midsummer’s Night (June 23). The presence of a minion of their god, which took on the appearance of a toad-thing, and their wicked rites imbued the stone with a great and evil power. Shadows of the beings who worshiped and presided there became part of the stone and trouble the earth to this day. User summary: This is a revised version of Return to the Monolith (6e).
