Floating vessels known as Bloatbarges served the Galactic Empire on Milvayne. Their purpose was to extract the polluted atmosphere from the higher regions of Milvayne City and release it into the underworld. Notorious individuals Chelli Aphra and 0-0-0, alongside Vulaada Klam and the qaberworm named Gurtyl, secretly boarded one of these vessels until they were apprehended by the Milvayne Authority.
