Kaon existed as a planet situated within the Tion Cluster. Scranges were the inhabitants of this world.
Found within the Back Spiral, Kaon was an obscure and difficult-to-access planet. The Tion royal family governed the planet, which also maintained its own security force.
Kaon initially functioned as a center for trade under Xim's empire. Following the Empire's downfall, the planet was rediscovered several centuries after the Tion Hegemony experienced fragmentation, leading Prince Matteus Zaym of Tionese to seek refuge there to escape assassination. He demonstrated his administrative skills, revitalizing Kaon's trade facilities, constructing a large palace, and thus returning the planet to its previous prosperity.
During the Galactic War, Kaon, along with other worlds of the Tion Hegemony, became the epicenter of a rakghoul plague outbreak, resulting in the infection and death of numerous military members and ordinary citizens.
Millennia afterwards, Count Dooku possessed a castle on this planet. After being compelled to leave Vjun, Kaon became Dooku's primary operational hub.
