Take a wild guess how a blonde gets an epithet like that
During a bloody battle, with massive losses on both sides, Elena was one of the few warriors still standing, her blonde hair soaked red with blood. Fatigued, and with frayed sanity, she carried herself to the nearest village. The villagers whispered of the wild eyed redhead, they dressed her wounds and gave her a much needed meal. Even in her distressed state she taught them to defend themselves from bandits, wherein they started calling her the Redmane. By this point she'd washed up but the epithet still stuck. The local militia, emboldened by the warrior, became the Redmanes and protected the town in Elena's stead.
