Battle against Crimson Dawn

Between 3 ABY and 4 ABY, a battle was fought between the Crimson Dawn Fortress-Flagship Vermillion and the Galactic Empire. After becoming aware that the Dark Lord of the Sith Darth Sidious was hunting her, Crimson Dawn leader Lady Qi'ra activated her spies within the various major powers of the galaxy to create chaos in order to buy her time to follow through with her plans. Qi'ra hid with the Orphans on an astronomical object aboard their ship, the Siroto, where they were eventually discovered by the Imperial Navy. The Empire deployed an Interdictor-class to prevent Qi'ra and her flagship from escaping.

As Qi'ra spoke personally with Sidious and outlined her plans to destroy him, Qi'ra sent the Vermillion to attack the interdictor. The Vermillion was attacked by TIE fighters and TIE/IN interceptors, but they were unable to prevent the ship from crashing directly into the interdictor, destroying both. Escape pods were deployed from the Vermillion, and Sidious ordered they all be destroyed, allowing for no one to escape.

The destruction of the Vermillion allowed for Qi'ra and the Oprhans to escape from the Imperials aboard the Siroto and as they left, Chanath Cha asked Qi'ra if they should pick up any potential survivors from the escape pods, Qi'ra thought for a moment before declining, adding that they could honor their sacrifice by seeing her plans through to the end.

The fact that Qi'ra survived was later inadvertently revealed to Vader by Cha. When Cha confronted Vader, he informed her that she would not avenge Qi'ra's death, which surprised the hunter. Vader sensed this and realized that Qi'ra had actually survived, adding that his Master would be fascinated to learn of this.
