Startrek has a well known mirror universe in TOS in which we see the federation is infact an empire, Kirk and Spock are evil and many other hilarious things.
This mirror universe is continued in Deep Space nine continues this universe with Kira as the commander of DS9 and the humans being a subjugated race.
What you may not know was that this entire divergent timeline was created when there was a fracture in AWOT back in 2004, in which many left to start afresh on the evil mirror site known only as WAYOT. My god Im really bored, I think I'll go post on WAYOT.
Im bored, Im going to post on WAYOT so fyyff.
