Bastion
this planet, the capital world of the Sartinayian System and Braxant Sector, was the political heart of the Empire in the dark times following the death of Grand Admiral Thrawn. Its true name is a secret kept well-hidden by the Empire. It was controlled by Moff Disra, who retained control during the rise in power of the New Republic. It was on Bastion that the surviving Moffs met with Admiral Pellaeon to discuss a possible peace treaty with the Republic. After the Imperial Remnant was formed and allowed to exist outside the Republic, the capital of the Empire was centered on Bastion for many years. During the early stages of the Yuuzhan Vong invasion of the galaxy, the planet and the Empire remained untouched for many years. Once the Yuuzhan Vong were soundly defeated at the Battle of Ebaq, they began to turn their attention to the systems they had passed. Among them was the area of space controlled by the Imperial Remnant. Bastion was attacked first, and the Empire was completely unable to defend itself. Bastion fell almost immediately, as the Yuuzhan Vong fleet decimated the Imperial warships and destroyed the planet's surface.
