Klossi Anno, a female Chalactan Padawan, dedicated her service to both the Jedi Order and the Galactic Republic during the Republic's final years. As a commander within the ranks of the Grand Army of the Republic, she lived through the Clone Wars and the enforcement of Contingency Order 66. Her master, however, died during the opening phases of the Great Jedi Purge.
Anno's Force-sensitive abilities were identified shortly after her birth on Chalacta, leading to her enrollment in the Jedi Temple academy on Coruscant. After dedicating herself to the study of the Force for numerous years, Anno graduated and was chosen by a Jedi Master to undergo individualized training. During her time as an apprentice, the rising tensions between the Galactic Republic and the Confederacy of Independent Systems reached a critical point, triggering the start of the Clone Wars. Reporting to the Jedi High Council, Anno was appointed as a Commander in the Grand Army of the Republic and given command over clone troopers.
The extended conflict concluded abruptly when the Republic's Supreme Chancellor issued Contingency Order 66, effectively dissolving the Jedi Order. As her clone troopers turned their blasters against her, Anno's master made the ultimate sacrifice, allowing Anno to escape. She fled to Dellalt, where she joined nine other Jedi fugitives in commandeering an SX troop shuttle from the newly established Galactic Empire. Despite being pursued by ARC-170s and a light cruiser, which resulted in the loss of two of their comrades, Anno and the remaining Jedi managed to evade capture and found refuge with the crew of the Drunk Dancer. In the company of smuggler Jula Shryne, the group eventually encountered Master Roan Shryne and Padawan Olee Starstone. Inspired by Starstone's unwavering hope and resolve, Anno and her companions decided to seek out Grand Master Yoda on Kashyyyk. After entrusting Master Shryne with her deceased master's lightsaber, the group set off towards their destiny on the Wookiee homeworld.
Upon their arrival, Kashyyyk was subjected to an invasion by the Empire, who sought to eliminate the Jedi hiding there. Under the command of Darth Vader, the Empire hunted down the Jedi fugitives, ultimately confronting them in battle. After the Sith Lord injured Jedi Knights Siadem Forte and Iwo Kulka, Padawan Anno launched an attack against the powerful cyborg. However, Vader effortlessly evaded her strike and slashed her across the back with his lightsaber. Rescued from the conflict and evacuated off-world by the other surviving Jedi, Anno recovered from her injuries and resolved to undermine the Empire through less direct methods. Following suggestions from her allies, Anno planned to work on construction sites or in agricultural projects, aiming to dismantle the Sith's influence through subtle actions rather than relying on a lightsaber.
