At the Dawn, the 200 humans of the upper Marzeel River who survived the Darkness belonged to the Garanvuli tribe - a small Star Tribe, saved by their leader Garan who descended from the Sky to save his lover Serias. The tribal center was Seriasdova? (Temple of Serias) which was a temple to Orlanth and Ernalda. They were Heortlings and agriculturalists. The leader of the Garanvuli at the Dawn was Volsax, a great leader who became chieftain of all the people in the mid- and upper Marzeel River valley. (Sources DP:LoT p. 59, Habitations at the Dawn).
