Also known as CT-27-5555, Fives trained with Domino Squad on Kamino before being shipped out to the Rishi Moon listening outpost. He survived the Separatist attack on the station there, and was transferred to the 501st Legion alongside his squadmate and fellow survivor, Echo. Fives and Echo were promoted to ARC trooper status after the defense of Kamino from Separatist invaders. He and Echo were later assigned with the difficult mission of freeing Republic prisoners from the daunting Citadel prison installation on Lola Sayu. He and Echo were later part of a mission to free Republic prisoners from the Separatist prison called the Citadel. Echo fell in battle, leaving Fives as Domino Squad’s sole survivor. Fives accompanied the clone trooper Tup to Kamino for medical testing, where he discovered a terrifying secret about the clones’ origins and ultimate purpose.

As Kamino’s chief medical scientist, Nala Se played a key role in engineering the Grand Army of the Republic – and worked to protect the army’s secrets. She cared for clones injured on the battlefield, supervising their rehabilitation even when Separatist attacks threatened her own life as well as the lives of soldiers. But she had a ruthless side as well, insisting to Jedi General Shaak Ti that the clones were Kaminoan property to be disposed of as their creators saw fit. Nala Se knew of the bio-chips implanted in the clones to ensure that they obeyed protocols such as Order 66. Obeying the orders of Count Dooku – whom she knew as Lord Tyranus – she sought to keep these implants secret from the Jedi.

A noble order of protectors unified by their ability to tap into the power of the Force, the Jedi Order were the guardians of peace and justice in the Galactic Republic. The age of the Jedi would end, however, due to a nefarious plot by the Sith Lord Darth Sidious.

Purged from the otherwise complete Jedi Archives is all evidence of the mysterious world of Kamino. A lonely world beyond the Outer Rim and just south of the Rishi Maze, few could have predicted that Kamino would become a key contributor to a massive shift in political power in the final days of the Republic. Kamino is a planet of endless oceans and storms. Few features mark its surface, save for massive stilt-mounted cities wherein reside the planet's natural inhabitants, the Kaminoans. From Tipoca City, the planet's Prime Minister rules. Lama Su closely monitored the operations of Kamino's most prized export: clones.

At the time of their introduction, the Republic clone troopers represented the future of galactic warfare. Far superior to battle droids, the clone troopers formed the backbone of the Republic's new military that waged war against the forces of the Confederacy of Independent Systems. So symbolic were they of the times, the galaxy-wide conflict that saw their debut took its name from their ranks: the Clone Wars.

Scheming, powerful, and evil to the core, Darth Sidious restored the Sith and destroyed the Jedi Order. Living a double life, Sidious was in fact Palpatine, a Naboo Senator and phantom menace. He slowly manipulated the political system of the Galactic Republic until he was named Supreme Chancellor -- and eventually Emperor -- ruling the galaxy through fear and tyranny.
