The Alrakis Sector is a region of non-aligned space near the Federation border with Elorg space. It contains the J’larre System
and the Tethe-Alla System. (“Renegade” [TFF]).
The Archanis Sector is a region of space on the border of Federation and Klingon territories, named for the Archanis System. It
was held by the Klingons until 2293, when it was ceded to the Federation at the Khitomer Conference. The Federation
established numerous outposts in the Archanis Sector during the 24th Century. (“Day of the Dove” [TOS], “Broken Link” [DS9]).
In 2373, the Klingons annexed the Archanis Sector at the urging of General Martok. Unbeknownst to the Klingons, Martok had
been replaced by a Changeling, and was using the situation in Archanis to incite war with the Federation. (“Apocalypse Rising”
[DS9]). The Klingons occupied much of the Archanis Sector until Chancellor Gowron reinstituted the Khitomer Accords in July
2373. (“By Inferno’s Light” [DS9]). In the Paris-universe, Archanis was used as a staging area for the alliance fleet before
engaging the Borg at Denatos VII. (“Nocturne in the Moonlight” [TFF]). In another parallel universe, the Klingons were an
agrarian species that used Archanis IV as a farming colony. (“Ghosts” [TFF]).
A heavily trafficked region of space in the Beta Quadrant located between Deep Space Seven and the Kilka Sector. Located in
non-aligned space, the Aurillac Sector was home to several planetary systems, its largest being its namesake, the Aurillac
System. (“Strike Zone” [TFF]). In 2395, the Romulans created a quantum inversion field in the Aurillac Sector to cover their
tracks while they annexed the Aurillac System. (“Ground Zero” [TFF]).
A region in the Alpha Quadrant on the border of Cardassian and Federation space. It contains the Bajoran System and station
Deep Space Nine. The region was considered highly strategic during the Dominion War because the terminus of the Bajoran
Wormhole fell within the confines of the Bajoran Sector. (Star Trek: Deep Space Nine). The Starlight was assigned to the
Bajoran Sector on stardate 73171.3 to transport some industrial replicators to Cardassian space (“Brothers and Sisters” [TFF]).
Bon Turani Sector.
A heavily trafficked sector in the Beta Quadrant, where Federation, Klingon, and Romulan territories converge. The Federation
Starbase 116 is located in the Bon Turani Sector, and serves as the political and economic hub for the region. (“Black Fire”
[TFF]). In 2397, there was concern the Garidians might invade the Bon Turani Sector. (“A Perchance to Dream” [TFF]).
The Calandra Sector is a region of space near Deep Space Nine. The Dominion used it as a staging ground for an assault on
Betazed in 2374. (“In the Pale Moonlight” [DS9]). Brian Keller’s ship was heavily damaged by an ion storm in the Calandra Sector
in early 2396. (“Cell Divisions” [TFF], “Brothers and Sisters” [TFF]).
A heavily trafficked region of space along the Romulan Neutral Zone. (“Face of the Enemy” [TNG]). Starfleet's Third Fleet was
assigned to patrol the Caleb Sector in August 2398. (“Cat and Mouse” [TFF]). The fleet intercepted and engaged an armada of
Tholian ships attempting to reach Romulan territory on stardate 75645. (“The Culling” [TFF]).
A region of space within the Klingon Empire. In 2397, the Klingons detected a Species 8472 bioship in the Chi’dan Sector. (“Ring
of Fire, part I” [TFF]).
Region of space within the Romulan Star Empire. In August 2398, a Tholian fleet crossed into the Glintara Sector to deliver
supplies to the Romulans. (“The Culling” [TFF]). In 2374, a forged holorecording created by Grathon Tolar depicted the
Dominion plotting an invasion of Glintara Sector. (“In the Pale Moonlight” [DS9]).
Region of space on the border of Federation and Romulan territories. (“Gambit, part I” [TNG]). The Vana’diel Nebula is in the
Hyralan Sector. (“Cat and Mouse” [TFF]).
A region of space along the Romulan Neutral Zone that includes the Jolan’isar Cluster. The Jan’tral Sector is heavily trafficked
by mercenary vessels, many of which perform extralegal smuggling activities. After the Elorg War reached its first climax in 2397,
the Federation established several checkpoints in the vicinity to curb smuggling. In March 2398, a Yridian garbage scow
attempted to bypass the checkpoints in order to deliver illicit medical supplies to the Jolan’isar Cluster. (“Monarch on the
Shore” [TFF]). While the checkpoints proved an effective measure in stopping contraband, it also discouraged legitimate
traders from approaching the region, consequently disrupting Romulan supply lines. In August 2398, the Romulans convinced
the Tholians to bypass the Federation checkpoints and deliver goods to the Jolan’isar Cluster. The USS Starlight detected the
Tholians on stardate 75609, but was unable to catch their vessel. In response, the Starlight collapsed much of the transwarp
network in the Jan’tral Sector to prevent further use of the Tholian’s transwarp drive. (“Cat and Mouse” [TFF], “The Culling”
A remote region of space charted by the Starlight in May 2397. It had been previously inaccessible because of a loose Romulan
claim to the region. (“Eleventh Hour” [TFF]).
A region of space on the edge of Tholian territory. In August 2398, the Tholians intercepted a Romulan scout ship in the
Kerelos Sector. (“The Culling” [TFF]).
Region of space located in the Beta Quadrant, near the Romulan Neutral Zone. The Kilka Sector is home to several star
systems, including Ka'Tula, Gildebron, and Breat, as well as the massive Alteran Expanse. Prior to 2395, the Kilka Sector was of
minimal strategic value to the Federation, however, the formation of the Elorg Rift in the Alteran Expanse and the subsequent
invasion quickly made it one of the most volatile regions within the Federation. (“Beginnings” [TFF]). In the years the followed,
the Kilka Sector was witness to several major attacks, including the Elorg offensive to take the Gildebron System in August
2396. (“Between Dark Places” [TFF]). The Elorg completely annexed the Kilka Sector several months later, in December 2396.
(“Meridian Dance” [TFF]). It remained under Elorg control until March 2397, when the Elorg were forced to surrender the
region to Federation forces after the Battle of Ciden. (“Confessions and Confrontations” [TFF]).
A region of space in the Beta Quadrant. It includes several star systems, including Welgaia, Darsaea, 92-Eridani, and Veridian, as
