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 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.

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!

Players and GMs of the Revenge of the Runelords Adventure Path should check out the Godsrain novel, the War of Immortals Sourcebook, and the Triumph of the Tusk Adventure Path (numbers 207, 208, and 209)
