Cyberiad

The Cyberiad was the shared consciousnesses of the Cybermen, similar to a hive mind. It contained the collective knowledge of every active operating cyber-unit on any level. The Cyberiad was what any upgraded organism was connected to in order for any Cyber-Planners to control them. In addition, basic cyber-units would sometimes greet any near-upgraded organisms to the Cyberiad. (TV: Nightmare in Silver)

When Rassilon found the Cybermen at the end of the universe, he gave them leadership, and joined their Cyberiad. (COMIC: Supremacy of the Cybermen)
