K'avor, a city nestled within the Outlands of the isolated planet Shiva IV, was a considerable distance away from Illyriaqüm, the capital. As one of the scarce Human outposts in that area of the world, K'avor met its end when an Imperial anti-matter bomb obliterated it in 3 ABY. The explosion utterly devastated the city, and a resulting, uncontrolled Cherenkov effect made its remains glow with a blue radioactive light. Despite this destruction, not every resident of K'avor died in the attack. Lobar Aybock, a person born in K'avor, was taken prisoner by the Empire; deeming him unsuitable for service as a stormtrooper, they sold him to Zygerrian slavers. After securing his liberation, Aybock went on to become a renowned shockboxer.
The initial appearance of K'avor was in Star Wars 53: The Last Gift from Alderaan, penned by Chris Claremont and published in 1981.
