Sar was a human warrior of the Kingdom of Evenhold who rose from obscurity to become a prominent member of the Guild of Free Adventurers and a hero of the realm. He is best known for leading a popular rebellion against the Brotherhood of Mlat and other dangerous cults in the late 1180s.

Sar disappeared in late 1199 while investigating rumors of the Minions of Y'Golonac operating near the Arcosian Swamp.
