According to The Husbands of River Song the Fourth Galaxy is, in fact, the Milky Way. (The ship is passing near Gamma Eridani in the year 5343.
I'm not even sure how to propose a move for something that major. -Derik ☎ 03:05, October 29, 2018 (UTC)
- The specific line in The Husbands of River Song is "We are currently cruising at warp factor twelve. Traversing the fourth galaxy of our seven galaxy cruise. Next is the Andromeda galaxy." While it's clear that the Milky Way was the fourth galaxy visited by their cruise, that's not necessarily the same as it being the Fourth Galaxy. – n8 (☎) 17:01, 29 January 2021 (UTC)
Merger with other Quinnis locations
In the 1960s, a common term for galaxy was "island universe", or "universe" for short. You can see this in Doctor Who in an Exciting Adventure with the Daleks, where Skaro is said to be in "the next universe but one", and in The Sons of the Crab, where Dr. Who travels "outside the home galaxy of the Milky Way and in an entirely new universe, the universe known to him as the Crab Nebula." (Later in The Sons of the Crab, "island universe" is specifically equated with "galaxy".) So it's completely unsurprising that the location of Quinnis in The Edge of Destruction is "the fourth universe", while The Edge of Destruction says it's "the fourth galaxy". To pretend there's a contradiction between these accounts obscures the very clear equivalence in the minds of the authors.
Likewise, in The Devil Goblins from Neptune, the Doctor saying that Quinnis is in Galaxy Four isn't a bungled reference, it's a confirmation that the setting of Galaxy 4 is what was referenced in The Edge of Destruction, just as The Eyeless confirmed that Galaxy 7 from Benny's Story is the Seventh Galaxy from The Infinity Doctors. We do not do the wiki any service by keeping these pages separate. – n8 (☎) 18:20, 29 January 2021 (UTC)
