During the Godsrain, a strange falling star with three tails was seen in the skies over the Saga Lands, yet no attempt to find its landing site has been successful. What fell to the world that night has now emerged, and as heroes work with the ruler of New Thassilon to help bring the nation to the global political stage, disaster strikes as a foe thought long dead rises and returns for revenge! Lord of the Trinity Star is a Pathfinder adventure for four mythic 12th-level characters. This adventure begins the Revenge of the Runelords Adventure Path, a three-part monthly campaign in which a group of mythic adventurers face the Runelords—some of the most powerful and legendary foes in Pathfinder's history, concluding an epic story nearly 2 decades in the telling. This adventure also includes information about Nocticula (goddess of art, midnight, and exiles), new and powerful magic items to claim, and several new monsters to threaten mythic heroes!
