BesGas Three was a floating tibanna gas refinery that was located above the Outer Rim world of Bespin, built shortly before the outbreak of the Clone Wars. Fearing rebuke by the decidedly anti-droid citizens of the Galactic Republic during the Clone Wars, the droid workers of BesGas Three hijacked the refinery, taking it into the depths of Bespin's life zone, and erasing it from all data registries. For twenty-five years, the refinery and its inhabitants would go undisturbed.
