- "Where else? Quantxi, the Junk Moon of Ord Mantell."
- ―Mas Amedda
Quantxi, also known as the Junk Moon of Ord Mantell, was one of at least three moons that orbited the Mid Rim planet Ord Mantell. The wreckage of Emperor Palpatine's yacht, the Imperialis, was located on Quantxi after the ship was stolen and destroyed. Also located with the Imperialis's wreckage were several excavator droids, which had been sent along with the ship to the desert world of Jakku as early as three years prior to the start of the Clone Wars.
After the Emperor's death at the Battle of Endor, Imperial Grand Admiral Rae Sloane set out to obtain any information on the mysterious past of Imperial Fleet Admiral Gallius Rax, who, unbeknownst to her, was a native of Jakku who had stowed away aboard the Imperialis as a boy and came into direct contact with Palpatine. Sloane snuck away to the Imperial capital Coruscant and asked Grand Vizier Mas Amedda for information on Rax, who informed her of the whereabouts of both the droids and the ship. The grand admiral sent bounty hunter Mercurial Swift to Quantxi, where he had a slicer take a look at the droids and uncover Rax's homeworld: Jakku.
