Joanna Harris

Joanna Harris was a vampire. She was born in Canterbury, England in 1087 on the same day that William the Conqueror died.

The leader of a vampire coven in San Francisco, Harris had, by the 20th century, taught herself rudimentary biology and was working on a substitute for blood that would no longer let vampires be reliant on their immoral hunting. In doing so she faced heavy opposition from her less scrupulous thralls, who thought her experiments were "trying to go against their nature". Unlike them, Harris found no joy in hunting, and believed that they only delighted in terrorizing mortals due to boredom (she, for her part, had "not been bored since they invented the Internet").

When the Eighth Doctor came to her and her vampires with a peace offering, proposing to help them research a blood substitute in exchange of which they would cease all attacks on humans, Harris, overjoyed at finding a more knowledgeable ally who shared her goal, agreed to pactise with him. As a token of trust between them, she had them partake in a bloodfasting, the first-ever (as far as she knew) between a mortal and a vampire rather than two vampires. (PROSE: Vampire Science)
