Hook says of his work, "The great Fenris wolf was one of the three terrifying children of the mythological Norse god Loki and the giant Angraboda. Loki banished all his children but Fenris, who was allowed to stay in Asgard only if he remained chained. The magical chain that held him was made from the spit of a bird and was as fine as spider webbing. Norse mythology says that should Fenris ever break his chain his destructive fury will end the world.

"My interest in Norse mythology stems from my Scottish ancestors who were descended from the Vikings. The Hook family coat of arms had on it a wolf with a forked tongue. I am drawn to Fenris because he is a creature who never really did anything wrong but was jailed because others were terrified of him."
