The southern water works, a facility located on the Outer Rim planet Calior, was positioned alongside a lake. The residents of Calior, employed by the regional government, were responsible for its construction. In the Imperial Era, Chief Regional Auditor Cygnus Anton of the Galactic Empire traveled to Calior. His purpose was to seize the southern water works from the planet's inhabitants, who at that point were the descendants of those who originally built it, and declare it Imperial property.
