Wruk Buk Tuk is the leader of the Nightwalkers, creatures that use to hunt and eat humans. He had been kidnapping humans from Elsa Fen‘s castle mostly to find Jack Frost. When he was finally found, he reveals they’ve been looking for him and need his assistance. They needed him to take down a sorcerer who has been terrorizing his people and controlling them. Jack agreed to help on the condition that, with MacDuff’s help, he start a peace treaty with the humans. After Jack defeated the sorcerer the treaty went into effect and there was no more conflict with his kind or the humans.
