Ivy Henson
From Tardis Wiki, the free Doctor Who reference
Ivy Henson was an elderly woman living in Gravestone House. Local children commonly thought she was a witch. When a terraforming device landed in the graveyard near her house, the graveyard became a swamp-filled forest and skeletons began to crawl from the ground. The device was animating them to work as repairmen and fix the device, allowing it to safely shut down and reverse the effects of the terraforming. The device also seemingly reduced Ivy's age, making her a much younger woman. (PROSE: Gravestone House)
