 The headwaters of the Upper Rhoyne lie in Andalos, the homeland of the Andals between Braavos and Pentos.The Rhoyne's course runs southeast to turn due south after Dagger Lake, where river pirates hide on and around the many lake islands.The Rhoyne gains in width considerably as it gets fed by more tributaries, until it opens into the Summer Sea in a delta near the Free City of Volantis.
