When we were kids, my brother's favorite Doctor Who serial was "State of Decay" from Tom Baker's last season. I don't think it's a particularly good story, but since my brother liked it so much, I ended up watching it numerous times.
"State of Decay" is a gothic vampire story (the last of the Fourth Doctor's gothic serials), taking place on a distant planet. The master vampire on the planet, who had fought the Time Lords when even Rassilon was young, has corrupted the three officers from the Earth exploration ship the Hydrax, turning them into immortal vampires. Over the generations, the names of the "three who rule" have evolved from captain Sharky, navigation officer Lauren MacMillan and science officer Anthony O'Connor to Zargo, Camilla, and Aukon, respectively.
It recently occurred to me that Camilla was (almost) a famous vampire name. "Carmilla" by J. Sheridan LeFanu was one of the two most famous vampire stories (along with Varney the Vampire) prior to the publication of Dracula. In British received pronunciation (a.k.a. "BBC English"), "Carmilla" and "Camilla" are basically homophonous.
What I was wondering was whether the names of the other vampires were allusions of a similar sort. I did not see any connections in the names "Zargo" or "Aukon," but I am by no means an expert of vampire fiction.
