Fandom: Star Trek (AOS)
Characters/Pairings (overall): James T. Kirk, Nyota Uhura, Spock, Leonard McCoy, Montgomery Scott, mirror!Marlena Moreau, mirror!James Kirk, Christine Chapel, Hikaru Sulu. Kirk/Uhura, Scotty/OC, references to a couple other pairings.
Summary: After four of the ship's officers never returned from an away mission, Spock reluctantly assumed the role of captain on the Enterprise while mourning the absence of his closest companions. Jim Kirk is meanwhile becoming the Terran Empire's most wanted fugitive in a slowly transforming mirror universe. Both of their fates may be affected by the self-fulfilling prophecy of a man who has very little to lose.
Overall Warnings: Violence (including some torture), secondary character death. This has been a WIP for a long while so it will have some inconsistencies with STID and onward (and obviously contains no spoilers for the second film).
