Acquara was an idyllic planet where John Crichton took refuge after Moya starbursted away, marooning him in space. Its people were subjects of the Hynerian Empire who were left on Acquara during the reign of Rygel X. A negative power vortex prevented them from leaving the planet, forcing them to remain Hynerian subjects. It also prevented them from using anything that required power to operate. ("Jeremiah Crichton")
