Navigational Officer Lauren MacMillan of the Hydrax was a human who fell into E-Space through a CVE. There she took on the name Camilla as one of the Three Who Rule. She was the consort of Zargo, the ship's former captain.

Biography
The Hydrax crossed from N-Space into E-Space where the crew found a unnamed primitive planet. There, turned into Vampires by the Great Vampire, they controlled the natives for a thousand years until the arrival of the Fourth Doctor, who killed the Great Vampire and therefore the Three Who Rule. She aged, decayed and crumbled into dust. (DW: State of Decay)

A clone of Camilla was later developed. (NA: Blood Harvest)
