Universe Two
From Tardis Wiki, the free Doctor Who reference
Universe Two was the name given by the Division to a universe that lay parallel to the Division's own, which they called Universe One. It was the universe through which the wormhole that the Timeless Child was found under led to, (TV: The Timeless Children) and the universe theorised by Tecteun to possibly be home to the Timeless Child's realm.
Tecteun was in the process of moving into Universe Two via the Division's Control ship after releasing the Flux into Universe One, deeming it to be "over" after the Timeless Child, the Doctor, ran away from the Division and became an inspiration to various peoples around it.
There existed another universe beyond Universe Two, which existed in a much larger multiverse. (TV: Survivors of the Flux)
