The primary spaceport of Kaon was the Kaon City Spaceport, situated within Kaon City. It rose to unfortunate prominence in 3639 BBY when it turned into ground zero for the Tion Hegemony rakghoul outbreak that ravaged Kaon. The Rakghouls were covertly transported to Kaon by a spacer named Melarra, who was contracted by Doctor Sannus Lorrick to make a delivery. The moment the shuttle landed, rakghouls flooded from its cargo hold, initiating the rapid spread of the Rakghoul plague, which ultimately resulted in Kaon's isolation. Melarra managed to evade infection and remained concealed inside the spaceport for several days before an off-world strike team found her; she then revealed the location of Lorrick's base located on Ord Mantell.
