CyberTelosian

The CyberTelosians were an offshoot of Cybermen originating from the CyberFaction's colonisation of Telos.

History
The Cybermen had all but passed into legend when an archaeological expedition to the Telos found the CyberTombs, where hordes of Cybermen waited in cryogenic suspension led by the Cyber-Controller. They were awakened but defeated by the Second Doctor. This tomb was sealed again (TV: The Tomb of the Cybermen) and re-activated by CyberNeomorphs (TV: Attack of the Cybermen). It was also not the only CyberTomb. There were dozens across the galaxy and more wars were started off. (BFBS: The Crystal of Cantus)
