Darth Gravus was a male human Sith Lord who served the resurgent Sith Empire during the Cold War and the Galactic War.
He serves as a quest giver of the Taris Story Arc for Empire characters in the video game Star Wars: The Old Republic, and a minor antagonist of the novel Star Wars: The Old Republic: Annihilation.
By the restart of hostilities with the Republic, he had earned a reputation of being ruthless and skilled at political maneuvering throughout the Empire. He oversaw Imperial operations on Taris, undermining the Galactic Republic's efforts to rebuild the planet after Darth Malak's bombardment.
After the death of Darth Hadra, head of the Sphere of Technology, many members of the Dark Council supported Gravus induction into their ranks, after he had reclaimed the resource rich world of Leritor.
For his numerous merits Gravus was considered as a potential candidate to ascend to the Dark Council during the year 3,641 BBY, but before he could accept the position he was killed by Darth Karrid, the other potential nominee for Darth Hadra's Dark Council seat after she goaded him into firing upon her ship the Ascendant Spear forcing her to destroy him.
Though the battle had ultimately been a success for the Empire, the recklessness of Gravus' attack on a fellow Sith Lord's ship discredited him in the eyes of the Dark Council.
