Galaxy Seven
From Tardis Wiki, the free Doctor Who reference
Galaxy Seven was one of the satellite galaxies of Mutter's Spiral.
History
At some point in humanity's future, the tourist board renamed a number of galaxies. These included the Sculptor Dwarf galaxy, which became Galaxy Seven.
- This may mean that the similarly named Galaxy 4 was also renamed by the same tourist board.
The Doctor visited the planet Arcopolis while he was travelling alone. This planet was located deep within this Galaxy Seven. (NSA: The Eyeless)
