Vivant eventually became commander of the Steadfast at some point after Makati's death, and the ship was part of Carnor Jax's battle fleet in 11 ABY. Vivant brought the Steadfast to assist the Emperor's Revenge in bombarding the New Republic forces on Phaeda. However, Vivant was forced to surrender upon the arrival of Rogue Squadron and – more impressively – the Lusankya.
"Vivant" is French for "alive" or "living".
In an early draft of Who's Who: Imperial Grand Admirals originally set to be published in Star Wars Gamer, Vivant is named as the Steadfasts first officer during the ship's time under Grand Admiral Afsheen Makati. However, Gamer was canceled and the article was redrafted to appear in Star Wars Insider. In the final draft, Vivant is not referred to by name, but mention of the ship's first officer and the events which occurred in the earlier draft still, albeit with less detail.
