Th oslak
was a Raven Clan member. He was the first person in the clan to offer Torak a place in his shelter, and Torak was always fond of him. When he gets the sickness caused by Tenris in the book Spirit Walker, he is driven mad, jumps off Guardian Rock into a stream and drowns.

It may be also be noted that despite the Law of not speaking a dead person's name for five winters after their death, Torak says Oslak's name aloud no less than 4 times throughout Spirit Walker and receives no reprimand for the people in his presence, such as Fin-Kedinn. However, this may just be an error.
