Publisher's blurb: A Pathfinder Society Scenario designed for levels 12–15. Using misdirection and misinformation, the Pathfinder Society has cornered a pair of its old enemies—a demoniac and an assassin—in the Five Kings Mountains. However, the two have taken refuge inside a sacred dwarven burial ground sacred to Magrim, and their desperate defenses have stymied the dwarves' initial assaults. It falls to a team of the Society's best agents to overcome these obstacles, avert impending blasphemies, and end these villains' treachery forever. Contents in Betrayal in the Bones also contribute directly to the ongoing storyline of the Grand Lodge faction.
