The Lusankya was a Super Star Destroyer that was the sister ship of the Executor-class Star DreadnoughtExecutor. It was constructed at Kuat Drive Yards on the edge of the Core Worlds whilst the Executor was constructed at the Fondor Shipyards.
The Battle of Thyferra marked the end of the Bacta War between Rogue Squadron and the Thyferran government, which was backed by Ysanne Isard.
Having collectively resigned their commissions in the New Republic Defense Force, Rogue Squadron waged a campaign for several months to undermine Isard’s rule, remove her monopoly on bacta, and free the prisoners held on Isard’s flagship, the Lusankya. The campaign ended with the Battle, which achieved all of the objectives except the last, and Isard, unknown to Rogue Squadron, escaped.
