Morningstar Tales: The Sword Below

From publisher blurb: What seems like a routine mission to recover an aristocratic heir soon becomes something far more dangerous as the players seek Brackenburn's heirlooms among the ruins of a long-dead civilisation. The Sword Below is a system-free Seven Scene System © adventure featuring original creatures & artefacts to surprise and challenge your party of players. This adventure is based on a well-received original one-off game written & GM'ed by the author. In fact, that is the whole point behind the Morningstar Tales line - they are tales of what has happened around the table here at Morningstar HQ.
