Zerelda Nineheart

Zerelda Nineheart was the leader of the resistance on Minalis world. She swore that she would lie down her life to free the ancient martians from the Kasakman Imperialists.

A Solidogram of Zerelda Nineheart was incarcerated in The Bekdel Institute, which she attempted to escape from with River Song and Missy. In reality, she was only trying to escape with them in order to relay information back to the Director, who wanted to know if the Doctor was alive, and assumed the two women would be the best people to ask.
