Attack on Voga
From Tardis Wiki, the free Doctor Who reference
As recalled by the Fourth Doctor, the Cybermen waged an attack on Voga, either "at "the end" of the Cyber-War (TV: Revenge of the Cybermen) or "after the end" of the Cyber-War. (PROSE: The Revenge of the Cybermen) Centuries later, the CyberNomads made a second attempt to destroy Voga, but were defeat by the Doctor. (TV: Revenge of the Cybermen)
