A Force-sensitive Twi'lek named Bazzra functioned as a member of the Knights of Ren during the Galactic Empire's reign. Bazzra joined the Knights between 3 ABY and 4 ABY as they carried out a Heist on Vader's Castle on behalf of Lady Qi'ra, who was the leader of Crimson Dawn.
Prior to the final years of the Galactic Civil War, Bazzra became affiliated with the Knights of Ren. Bazzra and her fellow knights embraced the dark side of the Force and an ideology centered around the red-bladed lightsaber known as Ren, all while under the leadership of an individual bearing the same name. During the [Imperial Era](/article/imperial_era], the Knights concealed themselves on various remote planets to evade detection by the Galactic Empire.
Eventually, Lady Qi'ra enlisted Bazzra and the Knights to become part of Crimson Dawn and assist her in defeating the Empire. Upon Qi'ra's orders, the knights were assigned the mission of infiltrating Fortress Vader to retrieve the Screaming Key from Vader's vault. Following the arrival of the Night Buzzard on the Gahenn Plains of Mustafar, the planet where Fortress Vader stood, the knights traveled towards the fortress from the south using their speeder bikes. They found an ancient entrance to the Sith cave concealed behind flowing lava, compelling Bazzra and the knights to use the Force to bypass the lava flow and enter the cave.

Upon entering the cave, Bazzra spotted what appeared to be a helmet on the ground. When the mask, seemingly containing the severed head of a Sith Lord, activated in her presence, she instinctively fired at the artifact out of fear. The knights progressed through the cave to the castle, where they encountered VaneƩ, who summoned Lava Troopers upon being attacked by the knights. Bazzra and the knights eliminated most of the troopers while Ren entered Vader's vault and secured the Screaming Key. However, Darth Vader himself soon arrived, swiftly killing one of the knights as Ren instructed the others to flee while he engaged the Sith Lord in a duel. After Ren successfully escaped the duel, the knights quickly departed the fortress with the key in their possession.

With the Screaming Key secured, Qi'ra dispatched the knights to a Dark side hellscape to protect The Archivist, who was en route to retrieve an item for Crimson Dawn. While some knights felt apprehensive about the location, Bazzra sided with Ren, acknowledging that they had limited options. After Ren used the Force to activate the Screaming Key, Bazzra and the others were startled by the agonizing sound it produced, which also awakened various petrified dark side creatures that began attacking them.
As they fled from the creatures of the hellscape, Ren entrusted the Archivist to Bazzra's protection, and she used the Force to carry her through the hellscape as the Archivist struggled to keep pace. With blasters proving ineffective against the creatures, Ren took command with his lightsaber while Bazzra continued to carry the Archivist towards the center of the hellscape. When one of the giant creatures approached them, Bazzra pushed the Archivist out of harm's way, leading to her own demise as she was crushed beneath a massive fist.
Bazzra possessed Force-sensitivity and was an adept of the dark side, but like many Knights of Ren, her lack of formal training limited her abilities. Nonetheless, she demonstrated the ability to use the Force to enhance her speed and movement, as seen during the Heist at Fortress Vader and when protecting the Archivist on the dark side hellscape. Bazzra also displayed proficiency with her blaster pistol.
Like her fellow knights, Bazzra wore a helmet and black clothing that concealed her entire body, including her Lekku. She also carried a Blaster pistol and an axe.
