Kerkoidia, a planet exhibiting a blue-gray hue, was situated within the Expansion Region, specifically at coordinates N-15 on the Standard Galactic Grid. Whorm Loathsom, a male Kerkoiden and a native of Kerkoidia, dedicated a significant time to serving in the planet's planetary defense forces. Loathsom ultimately attained the rank of general within the Confederacy of Independent Systems. Furthermore, the Retail Caucus had its headquarters established on Kerkoidia, alongside Loathsom's affiliation with the Confederacy of Independent Systems. Following the Battle of Endor, the New Republic successfully executed the liberate of Kerkoidia, wresting it from the control of the Galactic Empire.
The planet Kerkoidia made its initial appearance in the current Star Wars canon through the 2015 publication titled Ultimate Star Wars. Within the Star Wars Legends continuity, the planet received its first mention in The Clone Wars Campaign Guide, a 2009 supplementary material produced by Wizards of the Coast for the Star Wars Roleplaying Game.
