Aukon

Aukon was originally Science Officer Anthony O'Connor of the Hydrax before serving the King Vampire as one of Three Who Rule.

Profile
After the Hydrax accidentally left N-Space and passed into E-Space, along with the three, Aukon ruled the unnamed planet in E-Space as an advisor to Zargo and Camilla. The Three Who Ruled kept the population of the planet in thrall for a thousand years. Aukon wanted to sacrifice Romana and initiate Adric as a vampire at The Time of Arising. Aukon and the others died when the Doctor launched one of the scout ships into the heart of the Great Vampire. Like the others, he aged to death and decayed. (DW: State of Decay)
