Tomalin Pilke was a resident of Christmas on Trenzalore during the 750th year of the Eleventh Doctor's residency. He was the schoolteacher's son and worked in the greenhouses on the outskirts of Christmas. Like everyone else in Christmas, he had known the Doctor since childhood. At one point, Tomalin was briefly controlled by the Mara. (PROSE: The Dreaming)
