Isop Galaxy
From Tardis Wiki, the free Doctor Who reference
We know little about the Isop Galaxy (its size or distance from Mutter's Spiral, for instance) other than its great age: Boekind existed there before the Andromeda Galaxy had even formed from dust. (DW: Bad Wolf).
Though it did not nessecarily originate there, the Animus existed there for a time on Vortis (DW: The Web Planet) and later, the worlds of the Rhumons (MA: Twilight of the Gods).
