Brynn was a young boy who lived in a quiet village in England. Children started to disappear from the village, summoned by the mountain, which was actually a sentient spacecraft. Only Brynn and his friend Lissa were left. When Lissa disappeared, Brynn went to the mountain, where he encountered the Tenth Doctor and mistook him for a wizard. The Doctor told Brynn that the mountain was a spaceship and it wanted to create a story of its own. Brynn finished the story and rescued the children inside, allowing the ship to die in peace.
