Biography
Geralt was the son of sorceress Visenna and (presumably) a warrior called Korin. Shortly after being born, Geralt was taken by his mother to the Witchers' Place - the Kaer Morhen stronghold. After numerous mutations during the Trial of Grass, thanks to which he gained practically superhuman physical and mental abilities (increased reflexes, speed, strength and enhanced hearing) and finishing the witcher training, he embarked into the world on his horse called The Roach (he gave the same name to his every horse) to become a monster slayer for hire.

Even though Geralt did not believe in destiny, he demanded the unborn child of princess Pavetta and her husband Duny as a reward for his services. As the child turned out to be a girl, he did not take her. However, fate or blind chance cause Geralt and Ciri, the daugher of Duny and Pavetta to cross their paths thrice, and after the death of her grandmother, queen Calanthe, Geralt ended up taking care of the girl and loving her as his own daughter. His best friend was Dandelion the bard, while his lover and the love of his life was Yennefer.
