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, 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)
