Gwen was a witcher of the School of the Wolf who trained under Vesemir.[1]
Biography[]
At some point during training alongside Geralt, the students all participated in a training exercise run by Vesemir where blunt crossbow bolts were fired at the witchers so they could learn to parry them with their swords. Gwen and Hemminks were both hit in the face and subsequently carried off to the infirmary.[1]
