Publisher's blurb: A Pathfinder Society Scenario designed for 3rd- through 6th-level characters. The Pathfinder Society recently discovered that a rune-encrusted dagger in its vaults is somehow connected to an ancient weapon buried in the remote deserts of Thuvia. The weapon's precise location is unknown, so the Society dispatches a team of agents to explore the desert, using the dagger to guide the way. Unfortunately, the dagger is one of a matched pair, and the Society's enemies have its twin! Can the agents reach the weapon before their enemies do? What other surprises lay in wait? This adventure is the first part of the two-part Calamitous Dagger metaplot arc in the Year of Boundless Wonder.
