After-universe
Is it capitalised this exact way in any prose sources? If not, then post-universe, as with Tardis:Universe.
Talk about it here.
The After-Universe was the universe that existed after the destruction of the Doctor's universe. According to one account, it was a pink void inhabited by green mists of orbiting plankton, (PROSE: Millennial Rites) while according to another account, it was a deep-green void containing green planets, green stars, yellow mist and a green, electrical-looking energy.
The Zytragupten were one species known to inhabit this universe, (COMIC: The Stockbridge Child) and Saraquazel was also native to this universe. There were also mindless grazers which had eyeclusters, void-drifters which had (or travelled inside) triple helices, and fuction-breeders which nested in artificial constructs. This universe was connected to N-Space through pan-dimensional vacuum emboitments. (PROSE: Millennial Rites)
