Solitract plane
From Tardis Wiki, the free Doctor Who reference
The Solitract plane was where the universe was able to banish the Solitract, to allow for its own beginning.
As a result, the Solitract, a conscious universe was alone, forced away from the universe, so it would never learn how the universe had come about. The Solitract plane would become unstable if too many individuals from N-Space were in it at once. (TV: It Takes You Away)
