Grognak was the name given to a series of Gamorrean henchmen that served the Famine Lord of the NOE. As all Gamorreans look the same in the eyes of Dragus, he thought it would be easier to remember if all the Gamorreans in his service shared the same name. So far three Gamorreans have used the name Grognak. The first was killed in a sparring session with Lord Ninten, the second was eaten by a Rancor, and the third now resides on the planet Gamorr.
Usually Grognak is seen accompanying the Ewok Shaman, Graybeard.
