Moria™ – Through the Doors of Durin is a supplement for The One Ring™, the official tabletop roleplaying game based on the works of J.R.R. Tolkien. Set in the years before Balin’s doomed expedition, this supplement contains a hoard of Patrons, Landmarks, foes, encounters and treasures that a Loremaster can use to construct their own adventures in Moria – from a single desperate journey in the dark to a grand campaign to retake Durin’s Halls.
