Numeria's capital city of Starfall sprawls in the shadow of the region's most infamous ruin, Silver Mount. Somewhere deep within that ruined starship, the greatest of the Iron Gods is rising to power. Yet, before the heroes of Numeria can oppose it, they must first defeat the Technic League and the Black Sovereign in turn, for they control access to the legendary site. Will the clues harvested from an ancient android oracle and the technological wonders gathered from strange ruins across Numeria be enough for the heroes to prevail? Palace of Fallen Stars is a Pathfinder Roleplaying Game adventure for 13th-level characters.
