Brynn

Brynn was a young boy living in a quiet village in England. When 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 travelled to the mountain, where he encountered the Tenth Doctor, mistaking him for a wizard. The Doctor told Brynn that the mountain was in fact a spaceship, and that 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. (DWS: Once Upon a Time)
