Service history and disposition[]

The Borg Kingdom of the mirror universe was engaged in a multiversal conflict with the Aetherian Concordium in the 2410s. (STO - Kings & Queens mission: "Taken By Surprise")
In the year 2411, the Kingdom established Unimatrix 7400 in fluidic space to take advantage of that extradimensional realm's properties. This station was armed with tractor beam emitters, cutting beams and transphasic torpedo launchers. Leader Thaseen-Fei of the Aetherians told the Khitomer Alliance that the Borg could attack any universe in any time if they were allowed to remain in fluidic space. Because the extradimensional nature harmed Aetherians, the Khitomer Alliance mounted an expedition without their newfound allies.
The Undine, native to fluidic space and hostile to foreign incursions, were aware of Unimatrix 7400 but unable to overcome the station's defenses. Designate 6623 of the Undine vessel Merranau negotiated an alliance between the Undine and Khitomer Alliance forces investigating the unimatrix. The joint forces attacked the unicomplex and an away team, led by Admiral Kuumaarke and Captains Ezri Dax and Harry Kim, boarded the station. They fought the Borg and defeated the Borg King, Kim's mirror counterpart. With the station's defenses disabled from the inside, an Undine planet killer was able to destroy Unimatrix 7400.
The pocket of normal space the Borg had created in fluidic space was then occupied by the Aetherian Concordium. Thasen-Fei brought her ship, the Harmony, into that realm to serve as a vanguard against the Kingdom's return. (STO - Kings & Queens mission: "Scorpion's Abyss")
