R9-S1

"R9 = Look after ship/provide repairs. R9 = Help in any way possible."

- R9 introducing himself to Jeden and Nightingale Squad.

R9-S1 was an astromech droid created some time around the Stark Hyperspace War. Developing a personality after an incident involving a blaster and a drunk smuggler, R9 had an obsession with helping people, even when they didn't need any, to the point where he wouldclean hallways with a brush just to make himself feel useful. However, R9 was also excellent at controlling starships, the reason why he was selected as the astromech droid to keep up maintanence on the Saviour, the personal corvette of Jedi Master Jeden Vesal.

Origin
R9-S1 was first built during the Stark Hyperspace War as a droid for Jedi starfighters, primarily the Whitecloak starfighter and the then-experimental Delta-7, which would later be used right up to the Clone Wars. After returning to the Jedi Temple following the war, R9 accidentally fell from the hangar of the Temple and while he was able to stop his fall with his boosters, he soon became lost in the Coruscant underworld, eventually coming in to the posession of a smuggler sniper nicknamed 'Dune Rat'.

After many years working for Dune Rat, the smuggler got very drunk and accidentally shot his droid with his sniper, sending the poor astromech through a window. Found by a Jedi and recognized as a Jedi droid, R9 was brought back to the Temple for repairs, and entered the service of the Order once more, though he now had a personality, much like some other astromech droids.

When the Clone Wars broke out, R9 was assigned to the Phantom, the Venator-class cruiser under the command of Jedi Master Jeden Vesal. Earning the nickname 'Sweeper' from the Clones serving on the ship due to R9's compulsive need to not only help people but also make things look clean, R9 soon recieved a new job, and one of high stature: the personal astromech droid of General Vesal, and the caretaker of his Defender-class corvette, the Saviour.

R9 would stay with Jeden and Nightingale Squad (a group of four Clones, led by Jeden and his padawan Koses Lik-Har) for the rest of the Clone Wars and after the end of the war and the Great Jedi Purge, which Jeden and Koses survived.

Personality and characteristics
R9 was an advanced astromech droid for his time, with more tools than other astromech units and faster processing speeds for tasks ranging from basic calculations to computer hacking. R9 had a circular dome with an enhanced camera socket and motion sensors adapted in to his mainframe. His body was silver and blue and he bore the insignias of Nightingale Squad and the Jedi Order on his dome and body respectively.

R9 had a obsessive need to help people, whether they were Jedi, Clone troopers or a random citizen of Coruscant. While this meant he worked well as a caretaker (as he was always working), many Clones found it annoying, and the poor droid was almost shot by a Clone who heard him rolling around the barracks and thought it was a commando droid.
