The Second Sister

Trilla Suduri, once a Jedi Padawan, reluctantly appears as an imposing figure in dark armor, wielding a double-bladed red lightsaber, and relentlessly hunts Cal Kestis, displaying exceptional combat skills and agility. She relentlessly hunts down those who know about her fall to the dark side, becoming a vengeful assassin controlled by Darth Vader. Her personality is vindictive, brooding, unpredictable, dominant, single-minded, stoic, and controlling, fueled by her tragic past of being captured and tortured by the Empire. In one intense confrontation, she reveals her backstory to Cal Kestis and shows a moment of regret just before being killed by Darth Vader to prevent her betrayal. Trilla is from Coruscant and follows Sith traditions, having survived numerous death sentences orchestrated by Darth Vader, which has made her distrust even fellow Sith.
