Lissa

Lissa was a young girl living in a quiet village in England. When children from the village started to disappear, summoned by the mountain, which was actually a sentient spacecraft, only Lissa and her friend, Brynn, were left. Eventually, Lissa was taken by the mountain, and with help from the Tenth Doctor, Brynn rescued her and the other children, allowing the ship to die in peace. (DWS: Once Upon a Time)
