Killing Ground is a Virgin Publishing original novel written by Steve Lyons and based on the long-running British science fiction television series Doctor Who.

[1] It features the Sixth Doctor and Grant Markham, as well as popular enemies the Cybermen.

Upon arrival they discover that Agora has been conquered by the Cybermen, who have enslaved the population and return every three years to take the five hundred fittest humans for conversion.

As rebellion is plotted, there is another time traveller at work: the Cybermen obsessed Archivist Hegelia, and her novice research partner, Graduand Jolarr.

Details about the Cybermen including the term "CyberNomad" and references to Cyber-history, as well as the character of Hegelia and the Arc Hive from which she operates were originally conceived by David Banks for Cybermen, a study of the Cybermen both as a concept and a factual possibility and used with Banks's permission.
