Dungeons & Lairs #45: Cultist Monastery

Need to set up a session and have little time? Drop this in for play at levels 3, 5, 8, or 11!

Cultist Monastery is a Fifth Edition plug-in adventure for four characters with an average party level (APL) of 3, 5, 8, or 11. This module offers a general guideline on scaling the adventure for each level, and includes a table with adventure hooks for you to adapt to your own campaign. The characters must either aid, infiltrate, or defeat the Cult of Yil in their monastic home to claim the angry god's Extinction Arch, an artifact capable of penetrating the underworld.

You may also run this adventure as part of the Dungeon & Lairs Megamodule #2: Seekers of Yil. If you do, refer to the Seekers of Yil megamodule's adventure hook, "The God of Secrets Appears," to get your characters involved in the story. Learn more about the Seekers of Yil mega module on DMDave's Patreon.


Gardenyr Valxisys founded the Cult of Yil, using the cult and their monastery to safeguard an artifact called the Extinction Arch. Valxisys believes the artifact possesses the power to access the Narrow Path, a bridge to the underworld. A former adventurer, Valxisys used the tremendous wealth he gained in his career to construct a cathedral-like fortress around the artifact. The Extinction Arch is still part of the cathedral's structure—few people beyond Valxisys know of its existence, including members of his monastic order.

To the general public, the monastery is nothing more than a place of worship for the mysterious god called Yil, and its members nothing more than scribes, lore keepers, and beer brewers. However, those who knew its founder in his adventuring days know that the monastery harbors a secret. Now that Yil has demanded his artifacts of power be united once more, the Extinction Arch must be removed from the monastery, or the other artifacts must come under the protection of Valxisys' order.
