I am Geralt, the Witcher. I am a witcher. Shortly after being born, my mother, Visenna, gave me away to undergo training and, eventually, become a witcher at Kaer Morhen – the stronghold of the witchers.I survived mutations during the Trial of the Grasses, thanks to which i gained various witcher traits: high resistance to injury, poison, and diseases, as well as slowed aging, but also infertility; all witchers are infertile.
