Kluuus was a Gamorrean soldier who served the Dark Jedi Len Markus in 19 BBY. The Darkstaff imbued Markus with some of the powers of a Sith battlelord, allowing him to not be hurt when Kluuus was alive and within thirty meters of him, as injuries inflicted on him, would instead appear on Kluuus.

He was killed near the Ch'hala Heart Tree, when Markus was attacked by the Heroes of Cularin there in 19 BBY.
