Natasha (The Glass Princess)

Natasha was the daughter of an Archduke of a planet and the sister of Alex. They were friends of Princess Clio. When Clio turned five, she was poisoned by her Uncle Ferdand on behalf of his son Malvek, ruler of Dolmara. The First Doctor put Clio into stasis, preventing her from dying. Whenever Clio awoke, Natasha was there, but Clio wondered why she seemed to get older every time she saw her. (PROSE: The Glass Princess)
