Grolt was a lieutenant in the Imperial Navy. This male human served the Empire five years following the conclusion of the Clone Wars. Aboard the Perilous, the flagship of both Darth Vader and Emperor Sheev Palpatine during the mission to Ryloth, he was an officer noted for his Whiptree-like thinness. His death occurred inside a Perilous turbolift; Isval fatally shot him in the back of the head while he was escorting her and her supposed "repair team" toward the Star Destroyer's engine access point.
