Ileana de Santos

Ileana de Santos was a werewolf who had a romantic interest in the Doctor.

Originally a merchant's daughter, Ileana was transformed into a werewolf in 1812, by the notorious killer Pieter Stubbe.

By 2080, Ileana and her pack were living in Rio de Janeiro, Brazil. The de Santos family maintained a sprawling ranch in the country, accessible by a private train.

She was fiercely protective of her son, Victor de Santos.
