Mijos, a planet situated within the Anoat sector of the galaxy's Outer Rim Territories, was characterized by its swamps and the dangerous creatures that dwelled within.
During the Iron Blockade, enacted by the Galactic Empire to suppress information regarding their devastating loss to the Alliance to Restore the Republic at the Battle of Endor from spreading to the Anoat sector's populace, the Smuggler dispatched a member of their team to recover a cargo ship that had gone down on Mijos and was in danger of being submerged in the swamps.
Mijos first appeared in the Star Wars Legends online article "Galactic Gazetteer: Hoth and the Greater Javin," authored by Jason Fry, Daniel Wallace, and Craig Robert Carey for Wizards of the Coast and published in 2004. Its status was elevated to canon upon its inclusion in the mobile game Star Wars: Uprising, created by Kabam for iOS and Android devices and launched in 2015.
