Lamia
From Tardis Wiki, the free Doctor Who reference
Madame Lamia was Count Grendel's surgeon and engineer. She constructed the androids that Grendel used in his plots to kill Prince Reynart and the Fourth Doctor. Although she was a commoner, she and Grendel had a romantic relationship of some kind, although she herself acknowledged that he was not as devoted to her as she was to him.
After an android of Romana I failed to kill the Doctor at the Pavilion of the Summer Winds, she ran out of the Pavilion, but was accidentally shot and killed by one of Grendel's men. (TV: The Androids of Tara)
