Editing Star Trek (section)

=== The Mirror Universe ===
This isn't a faction; it's an alternate setting. Its own factions do bleed into the mainline starting in DS9. So it merits its own section.

The Mirror is a parallel universe in which [[Alternate History|things have gone differently]] in Earth's History. The main point of divergence appears to occur when the Vulcan scientists who landed at Bozeman, Montana in 2063 are not welcomed with alcohol and music but instead are killed and have their ship looted. It is equally clear that where the main universe is Noblebright the Mirror Universe is Grimdark. Instead of a peace loving Federation searching for knowledge and friendly cooperation for the betterment of all, Earth gave rise to the ''Terran Empire'' which seeks out new life and civilizations to conquer and enslave, as it had done with the Klingons. Pretty much it's the PG-13 version of the Imperium of Man with a bit more Grimderp. Junior officers get promoted by killing their superiors, those that fail at that get thrown in the agony booth for their troubles and Emperor gets the job by usurping the previous incumbent. As a rule, characters in the mainline become, in the Mirror Universe, a selfish asshole version of themselves (or have to go along to get along: O'Brien, Spock). Following comic book logic the uniforms for the female characters are more revealing, and facial hair is vogue. Occasionally people can cross over from one universe to the next due to technobabble and cause mischief in either realm.

Originally it was a one off TOS setting for an episode of the week, but it was brought back in a few novels and some romps in Deep Space Nine in which [[Fail|the Terran Empire had fallen]]. In Enterprise's fourth season it got a two parter that was pretty good and would have been an annual thing if the show had been renewed, this one having little crossover with the main universe (a ship from TOS ended up in the Mirror Universe and is salvaged after all it's crew have died). We also went there in Discovery, for better or worse.  Voyager never did the mirror universe, but instead got a homage episode with some alien historians in the far future getting the details wrong like historians tend to.
