Early tribes of Squibs were forced to wander Skor II to find resources. As some tribes founded villages, others traded from settlement to settlement, and haggling became an ingrained part of the Squib psyche. It was this bargaining instinct that allowed the Squibs to trade for hyperspace technology and bring their world to galactic prominence. Skor II remained loyal to the Galactic Republic during the Clone Wars. When the Confederacy of Independent Systems invaded the world in 21 BBY, the Republic fought to regain the world, with the ensuing Battle of Skor II won by Mace Windu and Clone Commander Cody. Although the government of Skor II later negotiated rubbish management contracts with the Galactic Empire, the king declared a pact of mutual support with the Alliance to Restore the Republic sometime before the Battle of Hoth.
Skor II was a terrestrial planet far from the Core Worlds in the Outer Rim reaches just west of the Rimma Trade Route. It orbited a small, red star called Squab as part of the Squab system. The world and its system were located in the Airam sector.
Though small, Skor II was dense, and its terrain and climate differed greatly from one region to another. The result was that the planet had seemingly boundless natural resources, although these were often localized: abundant timber was available in temperate zones, while salt was plentiful in sweltering coastal planes, and precious metals were concentrated in areas with mountainous terrain. Native fauna included a bird species that had green body feathers, red plumage on its head, yellow legs, and a long, yellow beak. Despite the fluctuations in climate, most beings found the world pleasant.
A sentient species known as the Squibs evolved on Skor II. The diminutive beings, split into various tribes, had to wander the world in search of daily necessities due to the uneven distribution of the world's natural resources. Nevertheless, they evolved an innate curiosity and proclivity for collecting that eventually forced some tribes to settle down and found villages. Other tribes kept up their traditional nomadism and took on the added mantle of traders, bringing goods from far-flung regions as they wandered the globe. Haggling attained a heretofore unseen importance in Squib culture and was perfected to an artform. Technology on Skor II advanced to early mass production.
Beginning c. 5500 BBY, traders from the Tapani sector began blazing new hyperlanes in the galaxy's southern reaches. Sometime during this process, Skor II received its first offworld visitor, a Dorcin merchant vessel. The Squibs negotiated for the technical specifications of hyperspace technology, and the Dorcin gained mineral rights to an arctic region of the planet. The Squibs took to the stars, and their world became progressively linked to the outside galaxy. The Tapani merchant hyperlane, which came to be known as the Rimma Trade Route, grew to be one of the most heavily trafficked in the galaxy, Inflows of trade and the Squibs' mastery of bargaining helped the planet prosper. Squibs spread across the galaxy; one group crash-landed on the planet Holador and was forced to eke out a living there. Sometime before 20 BBY, Skor II joined the Galactic Republic.
More than 40 years before the Battle of Yavin, a Squib named Ebareebaveebeedee ascended the planet's throne to become king. Beginning in 23 BBY, sectors along the Rimma seceded one after another to join the Confederacy of Independent Systems. Like other rimward systems on the hyperlane, Skor II found its trade with the Republic cut off. Nevertheless, the king proclaimed that the Squibs were "going nowhere" and staunchly placed Skor II on the Republic side of the dispute. The defection of Sullust to the Separatist side emboldened the separatists, and in 21 BBY, CIS battle droids invaded Skor II and seized Metrobig Interplanetary Blastport for use as a base from which to launch proximity mines along the outer Rimma. A force of Republic clone troopers led by Commander Cody and Jedi Master Mace Windu counter-attacked, recapturing the spaceport and routing the invaders in the Battle of Skor II. The Republic then left a contingent of peacekeepers on the world. Ebareebaveebeedee held a ceremony in Metrobig City, where he unveiled a bronzium statue of Windu and declared him a "Big Time Hero of Beyond-Squib Eliteness." Skor II remained in contested space for the remainder of the war.
Although Ebareebaveebeedee largely kept his planet out of galactic politics during the Galactic Civil War, he did sign contracts with the Galactic Empire to place Squib laborers aboard capital ships to work in waste disposal. After a group of Rebel agents aided the Squib government in vandalizing the Paradise system, home to the rival Ugors, the king signed a pact of mutual support with the Alliance to Restore the Republic. The world remained neutral after the Empire's defeat at Endor in 4 ABY. That same year, an Imperial warlord named Delvardus asserted his control over the systems of the Rimma Trade Route, but New Republic forces pushed him into the Deep Core by the middle of the year. Still, Skor II remained in neutral space through the Thrawn campaign of 9 ABY. The world eventually fell within the influence of Darth Krayt's Sith Empire by 137 ABY.
