2526

In 2526, an interstellar conference was held on Earth. The heads of many powerful planets gathered to sign an agreement to unite their militaries in an overpowering force against the Neomorph Cybermen. This event started the Cyber-Wars. (TV: Earthshock)

Joe Carnaby asked the Sixth Doctor if they could visit 2525 instead of the 59th century. The Doctor teased him by suggesting he planned on thwarting the Cyber invasion before it occurred. (AUDIO: Blood on Santa's Claw)
