Ten years ago, cavalry captain Eli was framed and exiled to the wastelands. Returning to Sunlight Hollow, he finds Dirk slaughtering innocents over a precious mineral vein. Rallying old allies Kieran and Lina, Eli fights back, gathers evidence, and clears his name. In the final battle, Kieran sacrifices himself. Eli kills Dirk with his own hands, but refuses the Federation's offer and rides back into the desert alone.
