Kiax and Ivax represented ancient Corellian deities of mischief, known as trickster gods. These two figures served as the inspiration for the Kiax and Ivax Nebulae, expansive gas clouds that caused considerable disruption to starship navigation within the Outer Rim Territories' Greater Javin area, many centuries prior to the Galactic Civil War.
The trickster gods Kiax and Ivax first appeared within "Galactic Gazetteer: Hoth and the Greater Javin," a 2004 online resource from Wizards of the Coast for the Star Wars Roleplaying Game.
