The Vivan cargo ship represented a freighter type employed by the Chiss Ascendancy during the era preceding the Vagaari pirate operations. These vessels transported essential life-sustaining provisions, including foodstuffs and oxygen stores sufficient for a duration of three weeks.
The Vivan cargo ship was featured in flashback sequences within Thrawn Ascendancy: Lesser Evil, the 2021 novel authored by Timothy Zahn and serving as the concluding installment of Star Wars: The Ascendancy Trilogy.
