The Battle of Zharrus, also known as the Battle of the Millennia and the Battle for the Perseus Arm, was a titanic battle of the War of the Yellow Cluster and its most climactic and defining moment. Emperor Eridakas, hoping to rally most of the Urilian navy and destroy the Unity's navy in a single decisive battle and ensure continued control over their sector of the Perseus Arm, led over 1,300 ships into a fight that led to a severe Urilian defeat. It has since been recognized as one of the largest and most important battles in galactic history. It is similarly recognized as a masterpiece of tactical brilliance and as Imperial Admiral Ta'acun's greatest victory.
