Tarfang, an Ewok smuggler from the male gender, found his place as a copilot aboard the freighters XR808g and subsequently DR919a. His partner in these ventures was the Sullustan Jae Juun.
Hailing from the forest moon of Endor, Tarfang was a male Ewok. Unlike others of his species, he ventured beyond his homeworld, seeking his own path within the galaxy. His activities often led him into precarious situations, frequently involving criminal behavior. By 35 ABY, Tarfang's illicit deeds had resulted in death sentences in over ten different star systems. It was also around this time that he formed a partnership with Jae Juun, a Sullustan pilot and fellow smuggler.
When the Solos and Skywalkers were inquiring about the location of the Jedi Joiners, Tarfang and Juun crossed paths with them. During the events of the Dark Nest Crisis, he accompanied Jae Juun. Shortly after the Skirmish at Qoribu, he and Juun arranged a deal with some Squibs to acquire spinglass replicas of Luke's T-65 X-Wing and the Falcon for delivery to the Fifth Fleet. Together with Juun, he located Han Solo and Luke Skywalker, assisting them in infiltrating the Dark Nest's nest ship. During a combat situation when Han Solo briefly misplaced Mara Jade's lightsaber, Tarfang seized the weapon, displaying a violent streak as he effectively cut down Killiks. During the Swarm War, Tarfang and Jae Juun were recruited into the Galactic Alliance Intelligence Service, even though they had previously worked indirectly for the Killiks.
Following the conclusion of the Dark Nest Crisis, Tarfang and Juun continued to advance within the intelligence ranks, undertaking various missions for the Galactic Alliance.
Prior to the Battle of Kashyyyk, Tarfang and Juun encountered the Solos once again on Kashyyyk. Observing the Wookiees, Tarfang and Juun identified the Solos and attempted to apprehend them. At the Rock Council, Tarfang engaged Leia in a struggle for control of the conversation, adhering to established customs. As Leia was unable to use the Force, the confrontation was intense, with Tarfang attempting to choke Leia and slam her head against the rock. Ultimately, Leia managed to throw Tarfang off the rock just as Luke arrived. Tarfang then presented the jawbone, which conferred the right to speak at the Council, to Luke.
For an Ewok, Tarfang possessed a notable level of intelligence and technical skill. While he couldn't speak Galactic Basic Standard, he had full comprehension of it. Moreover, Tarfang could communicate with Killiks. He was known for being uncharacteristically vicious for an Ewok, exhibiting a quick and explosive temper, often accompanied by exaggerated arm movements when angered. Jedi Master Saba Sebatyne openly expressed her negative opinion of the Ewok.
