Deep Space Station K-7

One of nine space stations strung along the Klingon frontier between 2218 and 2293, Deep Space Station K-7 began as a strategic outpost.^[3] Located one parsec from the nearest Klingon outpost, and near the disputed colony world of Sherman’s Planet, K-7 was tasked to help ensure the development of the world would favor the Federation under the terms of the Organian Peace Treaty.^[1] Most of K-7 consisted of storage areas and industrial fabrication facilities, and relatively little of the station was actually inhabitable.^[2] By the terms of the Organian treaty, all frontier stations of both nations were open to each others’ traffic, which made K-7 a hub for spies and confrontation.^[3] The Federation’s development project for Sherman’s Planet was threatened in 2266, when some 1,771,561 tribbles infested the storage bins of Quadrotriticale intended for the project, though this infestation ultimately helped uncover a Klingon sabotage attempt, as well as an undercover Klingon agent, disguised as a Human bureaucrat named Arne Darvin.^[1] Unknown to anyone at the time, Darvin’s future self had traveled back in time from 2373 in an attempt to alter events and prevent his dishonor, but Starfleet personnel from his time prevented him from altering the timeline.^[2] With the Khitomer Accords and the growing Federation-Klingon alliance, K-7 became a major transit point and meeting place for Federation and Klingon ships and personnel.^[3]

STO Timeline
In 2409, K-7 remained in active service, although heavily upgraded over the decades, and found itself on the front lines of a renewed conflict between the Federation and the Klingon Empire. Commanded by Commander Naomi Wildman, K-7 was a focal point for Starfleet ships entering sectors under active dispute between the two powers.^[4]
