Battle of the Emperor's Citadel

The Battle of the Emperor's Citadel, or the Battle of Byss, was a battle between the New Republic and the Dark Empire in 10 ABY at the reborn Emperor Palpatine's throne world of Byss. Following the Empire's truce with the Balmorrans which resulted in the export of the new state-of-the-art X-1 Viper droids, the insurgent New Republic had intercepted the shipment onboard the Star Hauler Reliance. The Rebel commandos then inserted themselves inside the war droids.

Upon landing on Byss, the X-1 Vipers quickly overpowered their Imperial guards at the spaceport before making their way down through the streets of the Imperial capital. They eliminated all opposition including various walker types and gunships. At the Emperor's Citadel, they took on and wiped out the Emperor's complement of walkers and turbolaser emplacements. However, the tide of the battle change when the clone Emperor Palpatine ordered his two top Dark Side Elite to unleashed monstrous Sithspawn known as Chrysalide Rancors. These monsters took on the X-1 Vipers, tearing them apart and scattering the Rebels. Luckily, the surviving Rebels were rescued by a group of smuggler ships led by Salla Zend. They then escaped into hyperspace, fleeing the battle. In retaliation for the Rebel attack on his citadel and their successful escape, Palpatine ordered the launch of the first projectile against the New Republic base on Pinnacle Moon.
