OMG New RPG 13th Age RPG - Eyes of the Stone Thief Supplement (Hardback) Game Book - Can you kill the dungeon before kills you? In 13th Age, living dungeons slither up through the underworld and invade the surface lands.

Now, it's hunting YOU. The Stone Thief rises. Enter it, find its secrets and defeat it; or die trying.
