Trial of the Underkeep
This Dungeons & Dragons adventure for 4th Edition takes place in a castle that disappeared beneath the earth a thousand years ago. When its sealed doors are opened, horrors emerge and threaten a nearby town. Players explore the subterranean ruins, confront an entity that has breached reality from another plane, and seek a way to survive its influence. The adventure includes 19 new creatures and 26 unique artifacts and treasures, some as dangerous as the monsters.
