SP - 99 SP - 99 was a protocol droid working for the Sith Empire during the Great Galactic War . Biography . After the Sith forced the Republic to sign the Treaty of Coruscant , Jedi Master Dar ' Nala and Jedi Knight Satele Shan were dispatched to the Outer Rim Territories to oversee the withdrawal of Republic troops from worlds ceded to the Empire in the treaty . SP - 99 was assigned to monitor the Republic and Jedi activities to ensure full compliance with the treaty . SP - 99 was standing just outside the cabin occupied by Master Dar ' Nala and Jedi Shan as they were discussing their dissatisfaction with their current assignment and with the treaty in general . Dar ' Nala sensed the droid and threatened to melt his memory core with her lightsaber . SP - 99 reminded her that she would be in violation of treaty were she to perform such an act . After Dar ' Nala stormed off , Shan assured the droid that the problem was not him , but his masters . While passing through the Kuat sector of the Core Worlds , their transport came under attack from a Sith warship . After Satele killed two Imperial commandos , he reminded her that the act was in violation of the treaty . She then sarcastically complimented his power of observation . After Dar ' Nala told Satele to flee after she was captured and to warn the Republic of the Sith ' s treachery , the pair made their way to an escape pod . She then told him that he could stay there with " His friends . " He refused saying " That is not my assignment . " When they were on board the escape pod Satele commented that she would save her master . He stated that that was highly unlikely and it would take approximately 500 , 000 years for the escape pod to be located in that sector . Satele sarcastically replied that would teach her patience . The escape pod was rescued from slavers by a Republic shuttle that was on route to Balmorra . The Jedi Master Orgus Din and Lieutenant Harron Tavus brought Satele and SP - 99 aboard . When Satele informed them of the Sith ' s treachery , SP - 99 tried to discredit her by saying she had not witnessed the attack from the beginning . Orgus Din , however , disregarded his interruption and resolved to inform Master Zym of the Sith ' s actions . Later on Balmorra , he offered to accompany Shan and Tavus in continuing their unfulfilled mission of overseeing the withdrawal of Republic forces from Dantooine under the terms of the Treaty of Coruscant . Following the attack on the Republic envoy Dar ' Nala , the Republic forces on Dantooine had refused to leave with their commander and were still engaged against Sith forces , in violation of the Treaty . SP - 99 reiterated that his assignment of monitoring the Jedi and the Republic was still unchanged . After Tavus caught SP - 99 spying on his conversation with Fortris Gall , he told him that it was his duty to do so to ensure compliance with the treaty . Tavus shot and destroyed the droid , telling him he wasn ' t accepting that as an excuse anymore . Personality and traits . Constructed by the Sith Empire during the Great Galactic War , SP - 99 was programmed to be completely loyal to his Sith Masters . Though he was able to interact at a personal level with Republic and Jedi personnel , he was viewed with suspicion and even disliked by some of them due to his Sith origins . Despite fighting on opposing sides , SP - 99 was still able to form a sympathetic relationship with the Jedi Knight Satele Shan who had a more conciliatory approach than her Master Dar ' Nala . Still his allegiance and defense of the actions of his Sith masters placed him at odds with other Republic and Jedi personnel .
