Kluuus, a Gamorrean warrior, fought for the Dark Jedi Len Markus during the year 19 BBY. Markus, empowered by the Darkstaff with abilities reminiscent of a Sith battlelord, possessed a unique defense: while Kluuus lived and remained within a thirty-meter radius, injuries directed at Markus were instead transferred to Kluuus.
Near the Ch'hala Heart Tree, Kluuus met his end in 19 BBY, during an assault on Markus by the Heroes of Cularin.
