The hunt for the seven shards of the Shattered Star leads the heroes back to the western coast of Varisia, to the multifaith monastery known as Windsong Abbey. The next shard appears to be hidden somewhere within the dungeons below the abbey. But when the PCs arrive, they find the monastery in ruins and held by savage giants and twisted fey! An ancient terror has returned home, and now dwells within the levels beneath the monastery—a terror who hopes to open the dread doomsday door within!
