Isop Galaxy

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).
