The Battle of Negui was a battle that took place on the planet of Negui in the Deep Core in 13 ABY during the Fourth Yuuzhan Vong Invasion. A group of primitive people who inhabited the planet, called the Republic Nation, who could use elements like water, earth, air and fire supported the Vong and had an airship convoy that was transporting a powerful artifact to a Vong airfield, where it was going to be used by them. The New Galactic Empire had to intercept and destroy the artifact.
