Discovered during the Great Manifest Period, the ocean world suffered a devastating natural disaster circa 5,000 BBY; however, the world's native sapients, the Chuhkyvi, were evacuated by a benevolent alien species to Iskalon before the catastrophe could wipe them out.[2]
During the Galactic Civil War, the Aquaris Freeholders began to seek liberation from the Empire, offering the Alliance to Restore the Republic access to their expansive underwater base. Accessible through a retractable surface landing platform, the Freeholders survived on the planet by piloting submersible aqua-skimmers to hunt the planet's marine wildlife. As members of the Rebel Alliance, many Freeholders left the world to attack the Empire holdings.[2]
Not playing much more of a role in the Civil War, the planet was conquered by the Yuuzhan Vong during their invasion of the galaxy during the reign of the New Republic.[3]
Among the most dangerous aquatic creatures in Aquaris' oceans were the enormous demonsquid, which were eight-tentacled mollusks with large jaws beneath a clump of arms. The gnooroop traveled in dense schools that could stretch up to ten kilometers long.[2]
