Belladoon, a world found in both the Outer Rim Territories and the [New Territories], occupied position K-3 on the Standard Galactic Grid. This planet was positioned on the Veragi Trade Route hyperlane, between the celestial bodies of Dantooine and Dubrillion. By 5 ABY, Belladoon was providing assistance to the Galactic Empire's military during the Galactic Civil War against the New Republic. During a gathering with his newly formed Imperial Shadow Council in that year, Fleet Admiral Gallius Rax discussed the Empire's strategy of leveraging its territories in the Outer Rim, citing Belladoon, Korrus, and Zhadalene as planets already under Imperial control.
The 2016 novel Aftermath: Life Debt, the second book of the Star Wars: The Aftermath Trilogy by Chuck Wendig, marked the initial reference to Belladoon.
