Immediately following the Treaty of Coruscant's ratification, the Republic transport ship known as the Envoy came under attack from Sith Imperial forces. This unexpected assault was masterminded by Jedi Master Dar'Nala, who sought to undermine the Treaty and restart the Great Galactic War between the Galactic Republic and the Sith Empire. As the Envoy traveled through the Kuat sector, it was intercepted by an Imperial battlecruiser. This warship was commanded by Captain Sivill of the Sith Navy. Dar'Nala, with the intention of falsely portraying the incident as Imperial aggression, commanded the Envoy to open fire on the cruiser. Sivill retaliated by returning fire and dispatching a boarding party to the Republic transport. Dar'Nala encountered the boarding team on the Envoy's bridge, putting on an act of resistance as Captain Sivill moved to take her into custody. The Jedi Master's true intention was to be captured, thus gaining access to the Sith cruiser. This also created a chance for her ally, Jedi Knight Satele Shan, to flee and inform the Republic about the Empire's supposed transgressions.
