Huloon, a planet situated in the Huloon system of Bootana Hutta close to the heart of Hutt Space, was once inhabited by the Huloons, a slave species. However, it was stripped of its population by the Hutts and repurposed as a nature sanctuary. Post-massacre, scattered groups of Huloons lived in systems neighboring their homeworld, longing for their return, yet they frequently endured mockery and abuse from the Hutts.
The initial appearance of Huloon occurred in The Essential Atlas, a work authored by Daniel Wallace and Jason Fry, which saw publication in 2009.
