The usual excitement of the Blackmoon celebration is amplified by the appearance of a solar eclipse, bringing a larger than usual host of lunar hermits, fanatics and witches eager to sell forecasts, issue omens, or cast harvest futures. The eager participants relish these sacred days when the world of the dead is said to draw closest to the living and whisper messages from the grave.

This 20-page level 5 adventure is created for Dungeon Crawl Classics with a strong old-school roleplaying focus. It can be easily adapted to any RPG system.

Among other elements, what makes Cathedral of the Undying stand out as a unique adventure is that PCs will not initially die when killed. A strange necrotic curse brings them back to life, but also a step closer towards becoming a mindless undead! PCs imagining this is a form of invulnerability may soon discover they have permanently joined the creatures of the night.
