Vesemir

Born into the role of a servant, Vesemir was dissatisfied with that as all his life could be, he dreamed of more and after a fateful encounter with a Witcher named Deaglan.

Once he got a taste of adventure, there was no going back to a simple life; so he made the decision to journey to Kaer Morhen to become a Witcher.

He puts up a very cocky front and is very knowledgeable about what he does however also is not good at admitting others may know more.

Vesemir was the oldest and most experienced witcher at Kaer Morhen in the 13th century and acted as a father figure to Geralt and the other witchers. Like many of the other witchers, he spent each winter in the fortress and set out on the path when spring arrived.

He was one of the few members of the School of the Wolf to survive the assault on Kaer Morhen. By the 1260s, he was the sole old witcher remaining; however, as he was only a fencing instructor, he didn't possess the knowledge necessary to create new mutagens in order to mutate more disciples into witchers
