Raven (The Dead Heart)

Raven was a female Mondasian. A heretic, she was selected by the religious leader to accompany a Cyberman scout into the Blisterlands in search of the Lizard Kings. They found the Dead Heart of the World and awakened Kho'dja, who told them the history of Mondas. The Cyberman killed him, declared that the Cybermen would take control of the planet, and had Raven placed in the cyberfication machinery, converting her into a Cyberman. (DWM: The Dead Heart)
