Sif-Uwana was a world situated within the Colonies region of the galaxy, identified as a planet. It served as the original homeworld for the people known as the Sif-Uwani, and governance was provided by the Sif-Uwana Council. During the period of the Alsakan Conflicts, Alsakan held dominion over the planet, however, control was ultimately ceded to the Galactic Republic. The Emperor's agent, Mara Jade, at one point made a visit to this location.
Within the galaxy, specifically in the [Colonies](/article/colonies-legends] area, Sif-Uwana was a planet belonging to the Sif-Uwana system. The Sif-Uwani people originated from Sif-Uwana and were known for their laid-back attitude toward financial matters and administration. The Sif-Uwana Council, an organization solely composed of Sif-Uwani, governed the world.
Sif-Uwana, which eventually became part of the Northern Dependencies, was under the control of Alsakan during the [Alsakan Conflicts](/article/alsakan_conflicts-legends]. However, some years, specifically hundreds, following the conclusion of the Fifth Alsakan Conflicts, the world transitioned to the control of Alsakan's adversaries, namely the Galactic Republic.
By the year 0 BBY, the thief named Kels Turkhorn had come into possession of a verified Sif-Uwana credit voucher. At some juncture, Mara Jade, the Emperor's Hand, journeyed to the planet for official business, acting under the instructions of Emperor Palpatine, the leader of the dominant galactic government, the Galactic Empire, which was also in control of the region where Sif-Uwana was located. Around 6 ABY, Talon Karrde, a smuggler, impersonated a chief purchasing agent from Sif-Uwana of the Sif-Uwani Council, during diplomatic talks on the world Kaal, claiming that the Sif-Uwani Council wanted to establish their own harvesting operations on the Unis Islands. Two years later, Karrde would again pose as the Sif-Uwani agent, during an investigation on the planet Varonat.
The first mention of Sif-Uwana occurred in Timothy Zahn's First Contact, a short story from 1994 that was featured in Star Wars Adventure Journal 1. The planet was mentioned again in 2009 in the reference book The Essential Atlas, authored by Jason Fry and Daniel Wallace, which situated it within grid square K-8.
