Three Who Rule

The Three Who Rule were three Humans called Aukon, Camilla and Zargo, who were mutated by the Great Vampires.

They are pale and had fangs. They had increased strength and had hypnotic powers, being able to control Gallifreyans, Alzarians and bats. The Three feed on the blood of other creatures, preferring that of living to dead creatures. They can convert living humans into vampires like themselves. Though they are technically immortal, if their Great Vampire progenitor dies, they quickly age and disintegrate, as they did when the Doctor flew a ship into it's heart. (DW: State of Decay)
