What is the “The Tenebrous Stone” adventure about?

The Tenebrous Stone is an level 3 one-shot that can be run in about 2-3 hours. The action takes place in the remote kingdom of Damara (located in the frozen north eastern corner of the Forgotten Realms) near the farming village of Helmsdale. Players are tasked by the village elders to with tracking down a missing monk who was last seen in a nearby stone quarry that is now believed to have been taken over by an ancient evil.

Players will have to investigate the quarry, battling undead and cultists of the demon prince Orcus who have recently discovered a powerful relic that emits fear and despair. It’s a familiar set up, but also showcases the new adventure format that will be used in the upcoming Adventures in Faerûn DM supplement.
