Welcome to the STAR TREK Expanded Universe!

STEU is an encyclopedia and database, like Memory Alpha or Memory Beta, except for Star Trek fanworks instead of canon or licensed works. Fanworks include fan fiction, fan films, fan-created audio dramas, RPGs, and more, both past and present. We also chronicle the history of Star Trek fandom itself. If it's something fan-created, or a part of fanon lore, information about it belongs here. If you are interested in contributing and don't know where to start, see our most wanted pages, or view recent changes where you can see and assist in current efforts. Please enjoy the wiki!

STEU is not a storytelling venue or a host for fan fiction itself. All articles here must be sourced and properly attributed. If you are looking for a place to create your own stories, there are many fan fiction archives and other online hosts where you can post your work, and we look forward to seeing the fruits of your efforts!

Terran Empire insignia.

The "mirror universe" is the informal name for a parallel universe, so named because many people and places are "opposites" of their counterparts in "our" universe, with "evil" replacing good and vice versa.

The history of the mirror universe during the 22nd to the 24th century has been shaped largely due to influence from the "primary" universe.

During the 22nd century, the capture of USS Defiant, a Starfleet vessel from a hundred years in the future, helped to solidify the Terran Empire's grip on power and dominance over the quadrant. (ENT: "In a Mirror, Darkly", "In a Mirror, Darkly, Part II")

The chance interaction between Starfleet officers from the primary universe during the 23rd century, with their counterparts from the mirror, who eventually led to the downfall of the Terran Empire and the rise of the Klingon-Cardassian Alliance. (TOS: "Mirror, Mirror"; DS9: "Crossover")
