Donn Stroud brought the heat with Plangent. I had no idea what that word meant, a loud reverberating melancholy sound. Sisters of Mercy? He made the essential Dungeon Crawl Classics book Lesser Key of the Celestial Legion, now is this a classic dungeon crawl for Old School Essentials? I bet it is.

Old-School Essentials Adventure

An idyllic cove harbours deep secrets. Magic and sound are entwined harmoniously, while dark things lurking in the depths rise to explore new avenues through previously locked portals.
