A Pathfinder Roleplaying Game adventure for 15th-level characters, this volume of Pathfinder Adventure Path is part 6 of 6 of the Kingmaker Adventure Path, in which the heroes win and defend a small kingdom from threats foreign and domestic. PCs should advance to 17th level by the end of this adventure. This adventure begins after the War of the River Kings has ended—the PCs, be they the war’s victors or losers, are faced with the task of rebuilding their kingdom or perhaps helping to rebuild Pitax. Yet soon after the war is over, a new peril strikes the region as strange monsters and violent bursts of rapid vegetation growth and bizarre weather plagues the Stolen Lands. At the same time, the PCs learn that one of the treasures discovered in Pitax’s House is a nascent vorpal sword, a weapon of immense power, and as the strange weather and blooms of life and monstrous incursions increase, so does this sword’s intelligence and power. The PCs soon learn that their kingdom faces an invasion, but this time not from the physical world. Some fell force from the legendary First World is attempting to expand into this world, and when the PCs begin to fight back against these verdant blooms, they discover that it’s possible to step from this world into the First World realm of Thousandbreaths. There, the PCs face powerful new threats unlike anything they’ve seen before, and learn that the dangers facing their kingdom are even greater than they feared, for the fey ruler of Thousandbreaths is about to absorb the Stolen Lands into a bauble for her own purposes, an act that would scour clean the region and leave behind nothing but a wasteland.If the PCs hope to save their new kingdom from this threat, they must combat the nymph queen Nyrissa both by stopping the various blooms in their kingdom and by traveling into Thousandbreaths itself to confront the dangerously insane nymph.
