In this new timeline, the First Doctor never left Gallifrey and eventually became Lord President, continuously appeasing the massive Dalek Empire. Because of this, and because of its tactical position, Earth had been invaded a dozen times, the attackers including Robot Yeti, Imperial Daleks, Sontarans, Cybermen, Ice Warriors, Draconians, Sea Devils, Silurians, Terileptils, and Zygons.
The Doctor, Ace and Bernice retrieved the segments which had been scattered along the Doctor's time track, allowing the White Guardian to restore the universe. Back on Gallifrey, the First Doctor and Susan decided to steal a TARDIS and leave to protect the Hand of Omega. (COMIC: Time & Time Again)
