Constant Division
From Tardis Wiki, the free Doctor Who reference
The Constant Division was a region of space which was visited by the Thirteenth Doctor and Team TARDIS in the 67th century. They were on the hospital ship Tsuranga when it was situated on the edges of the Constant Division. Astos noted that they were close to disputed territory, while the Thirteenth Doctor observed that there was a lot of space junk and asteroids outside.
A vid-briefing series entitled Perils of the Constant Division provided information on Davros, the Cybermen, the Ood, the Weeping Angels, the Raxacoricofallapatorians, the Sontarans, the Silents, the Silurians, the Zygons and the Pting. (TV: The Tsuranga Conundrum)
