When they were out on a journey, Hasten's group captured the Twelfth Doctor and Clara Oswald. The Doctor attempted to scare them away with the sonic sunglasses, but Hasten solve that problem by snapping them in half.
After a two-day journey back to their village, Hasten was led to believe that the Doctor was Odin, the Norse King of the Gods, only for another another false Odin to appear in the sky and invite the village's best warriors to dine with him in Valhalla. A few of the Mire soldiers teleported down to Earth, and Hasten was one of the Vikings transported to their spaceship.
