"On heavily populated worlds in those sectors, such as Uviuy Exen in Shwuy and Trammen in Harron, every single line squad has been completely armed with light repeating blasters."
―A compilation of Imperial documents by Rebel Alliance Major Arhul Hextrophon[src]

Uviuy Exen was a heavily populated planet in the Colonies' Shwuy sector. It lay at the intersection of the Hydian Way and Shwuy Exchange hyperlanes, which led various starships traveling along those routes to pass through the Uviuy Exen system.

During the Clone Wars, Uviuy Exen remained loyal to the Galactic Republic, and by 4 ABY, it had become a fortress world of the Galactic Empire. Around the time the Battle of Yavin took place, Imperial Army line squads on the planet were completely armed with light repeating blasters. A few years later, Uviuy Exen was the site of several battles between the New Republic and Imperial forces.


Uviuy Exen was a planet[4] located in the star system of the same name, a part of the Shwuy sector[1] in the Northern Dependencies portion of[2] the Colonies.[1] Uviuy Exen lay at the intersection of two hyperlanes[2]—the minor hyperspace route[5] known as the Shwuy Exchange, which connected the planet to the Dankayo system, and the Hydian Way super-hyperroute, which linked it to the Eeropha and Wakeelmui systems.[2]

Between 25,000 BBY and 22,000 BBY, a number of early hyperlanes connected Uviuy Exen to the systems of Chagri, Nouane, Yabol Opa, Brentaal, Coruscant, and Palanhi;[2] however, by 17,000 BBY, these had coalesced into a single route running from Chagri to Brentaal through Uviuy Exen.[3] That hyperlane would eventually be known as the Corsin Run, and by 3694 BBY, it had been merged into the modern Hydian Way.[2]


Conflicts and changes of governmentEdit

Although space surrounding the Uviuy Exen system became well-explored between 20,000 BBY and 15,000 BBY, the planet had already been incorporated into the Galactic Republic by 22,000 BBY.[2] By 17,000 BBY, Uviuy Exen had allied with the planet Alsakan in its struggle against Coruscant for the status of the Republic's capital,[3] yet it remained in space loyal to the Republic during the Clone Wars of 2219 BBY.[2] Early in that conflict, Uviuy Exen lay at the intersection of territories that the First, Third, and Seventh Army of the Republic Military were tasked with defending against the military forces of the Confederacy of Independent Systems.[3]

Light-Repeater negwt

All Imperial Army squads on Uviuy Exen were armed with light repeating blasters.

By 17 BBY, Uviuy Exen fell under the control of the Galactic Empire,[3] and by the time of the Battle of Yavin, every line squad of the Imperial Army on the planet had been completely armed with light repeating blasters.[4] Uviuy Exen had become an Imperial fortress world by the time of the Nagai invasion in 4 ABY.[2]

The military of the New Republic defeated the forces of Imperial Warlord Zsinj at Uviuy Exen in 6 ABY as part of a drive to push Imperials up the Hydian Way,[6] and the world had fallen under New Republic control that same year. Four years later, however, another battle was fought in the Uviuy Exen system when Imperials advanced from the Chagri system to the Brentaal system.[2]

A world at crossroadsEdit

Due to Uviuy Exen's strategic location on the Hydian Way and the Shwuy Exchange, on several occasions the system was passed through by transiting starships traveling along those hyperlanes. It was visited in 27 BBY by the colonization and exploration vessel Outbound Flight on a shakedown cruise through the territory of the Galactic Republic. During the Outer Rim Sieges phase of Clone Wars, Republic fleets chased Confederate forces Rimward, including along the Hydian Way through Uviuy Exen.[2]

In 0 BBY, several vessels involved with the ongoing civil war between the Galactic Empire and the Rebel Alliance traveled through the Uviuy Exen system. First, the Imperial Star Destroyer Devastator chased the Tantive IV, the corvette of the Rebel-aligned Senator Leia Organa, between the Outer Rim worlds of Toprawa and Tatooine. Subsequently, the Devastator, with the captive Senator aboard, traveled back through Uviuy Exen to rendezvous with the Imperial Death Star battlestation in the Outer Rim's Horuz system.[2]


The Death Star battlestation passed Uviuy Exen on its path to Alderaan.

Shortly after that, when Grand Moff Wilhuff Tarkin, the officer in charge of the Death Star, decided to demonstrate its offensive capabilities upon the Core Worlds planet of Alderaan, the Imperial Navy cleared the hyperlanes for the mobile station to move to its target unhindered, traveling through the Uviuy Exen system on its path. Finally, the light freighter Millennium Falcon, whose crew possessed the schematics for the Death Star and had rescued Organa from the station in the Alderaan system, raced through Uviuy Exen on its way to the Rebel base on the Outer Rim moon of Yavin 4.[2]

The New Republic's Rogue Squadron passed through Uviuy Exen in 6 ABY while relocating[2] from their base on the[7] Colonies[8] planet Talasea[7] to Noquivzor, also in the Colonies. New Republic forces traveled through the Uviuy Exen system in 17 ABY before engaging the Imperial Remnant at Champala in the Chagri system, and again in 27 ABY prior to a confrontation with the extra-galactic Yuuzhan Vong invaders at the Colonies world of Borleias.[2]


Uviuy Exen was a heavily populated world by the time the Battle of Yavin took place,[4] with the population of its system numbering between 500 million and 1 billion around 25 ABY.[2]

Behind the scenesEdit

Uviuy Exen was first mentioned in the 1989 Imperial Sourcebook, written by Greg Gorden and published by West End Games for Star Wars: The Roleplaying Game.[9] The 2009 reference book The Essential Atlas placed the Uviuy Exen system, and therefore the planet Uviuy Exen, in grid square L-9.[2]
