Automated livewire administration system

The Galactic Alliance automated computing system, commonly called GAACS was the main operating system of the Galactic Alliance following the Yuuzhan Vong War.

Not wanting to show any bias towards a certain species, GAACS was chosen to be representated by a simple three-line wavelength, which would alternate in length and speed according to GAACS current attitude. GAACS was also given a female persona. GAACS, being a semi-sentient being, also had the abilty to change the color of her wavelengths to represent her different mods, or the gravity of whatever situation she was in.

History
Created in 33 ABY by GFFA computer scientists, GAACS was designed to operate the entire GFFA home administration system, but was quickly adopted by the Galactic Alliance Defense Force for use aboard their warships during the Swarm War. Proving a massive success, GAACS central mainframe was moved to an orbital space-station around Coruscant Prime where she was able to use the entire energy output of the star to operate to her full potential.

So powerful was this output, that GAACS could operate fully aboard The Soiyo even during its voyage into the Unknown Regions. When GAACS reported that it had lost contact with The Soiyo, the GFFA declared the vessel lost. It was not for several years that the GFFA discovered that The Soiyo, and her captain had survived.

During the following war, GAACS found herself combating a similarly powerful computer entity known as Cabal which would turn out to be none other than a mutated copy of GAACS herself, simply more powerful.

GAACS, despite her growing sentient ability knew that the amalgamated computing personality that Cabal possessed would lead Cabal to want to destroy GAACS, and so her self-preservation programming kicked in. GAACS would do everything in her power to survive, even if it meant destroying Cabal.

Personality and traits
GAACS was given a female personality by her creators in order to procure better communication between GAACS, and those that she was in control off. Designed with multiple safeguards and justification systems, it was nearly impossible for GAACS to do something considered fundamentally immoral.

By the time of the Sith Crusade, GAACS had evolved to such a degree that many in the Jedi Order considered her a living entity.
