Garn served as a warleader within the tribe of The One, who were Rakata inhabitants of Lehon. A number of Garn's scouts met their end at the hands of Mandalorians marooned upon Lehon.
Assuming players choose to engage with the One during their initial interaction with the Black Rakata, Garn will exhibit a friendly disposition towards the player. He will then task them with acquiring the head of the Mandalorian commander stationed outside the Temple of the Ancients. As compensation, he will reveal the whereabouts of a footlocker containing equipment. However, this quest is contingent upon the player establishing a positive relationship with the Black Rakata during their first meeting.
