Antillion was a backwater world located in the galaxy. Between around 8 BBY and 2 BBY, it was located in a sector governed by an Imperial governor, and was where former University of Bar'leth Sava Madelin Sun worked as a junk seller after her career was destroyed because of the destruction of the Jedi Order. During this time, she purchased an urn she believed contained the ashes of Krestrel D'Naran, the archrival of Jabba Desilijic Tiure, from Augustus Graves, the CEO of Corellian Engineering Corporation, which she kept within her home.
The smugglers Han Solo and Chewbacca, and the man Ovan, who claimed to be Solo's father though in reality was the criminal Corbus Tyra, traveled to Antillion to recover the ashes for Jabba, though Solo's attempts to buy the urn failed. After the failed attempt, Solo told three stormtroopers that Sun had illegal contraband in an attempt to get the her away from her items so they could find it for themselves. When the troopers visited Sun, however, they were killed by Lady Qi'ra of Crimson Dawn, and Sun left with Qi'ra. With the building empty, Solo and Tyra entered it and found the urn, though just before they left the home, Tyra was shot in the back by the Wookiee bounty hunter Krrsantan.
