History
Origin
According to the ArcHivist Hegelia, the CyberNomads were a Cyber-subspecies that had branched off from the early CyberFaction based on Planet 14, who themselves branched off from the CyberMondasians of the planet Mondas. (PROSE: Killing Ground, AUDIO: The Early Cybermen)
The War
At some point, the CyberNomads entered what Jolarr described as a "vicious and protracted war" with Voga, the famed planet of gold and home planet of the Vogan. Ultimately, the Cybermen were defeated by the Vogans and presumed to be extinct. (PROSE: Killing Ground, AUDIO: The Early Cybermen)
