R3-T7 was an Astromech Droid in the service of the Galactic Republic, stationed on Naboo. He was assigned to be the co-pilot of Senator Amidala's head of security during a trip to Coruscant, in which the royal starship was escorted to Coruscant so that Senator Amidala could cast her vote on the creation of a Clone Army. R3-T7 witnessed the first attempted assassination of Amidala as the royal starship exploded, killing everyone aboard. Thankfully, Amidala wasn't aboard at the time, instead being the pilot of one of the escort craft. Unfortunatly for T7, a piece of flaming debris from the exploding ship impacted his chest and destroyed him instantly, as well as severely damaging his ship. Poor guy.
