Yurdak Fav was a female Shistavanen who worked as a scout, according to legends.
Her bright yellow eyes indicated that Yurdak Fav was born in Inner Uvena, which is part of the Uvena system. She was the youngest member of a family with a long history of serving as Republic scouts, a lineage that could be traced back to her great-great-grandmother. Following in their footsteps, Fav became a member of the Republic Survey Corps.
When the Galactic Empire was established, many Shistavanens left the Corps. Fav was one of the scouts who found themselves without a job as a result.
Before 11 BBY, the Uvena System Constabulary contacted Fav and Lak Sivrak. They were tasked with locating Alpha Premier Korta Sarc, who had gone missing and was eventually discovered murdered inside the Jenet embassy. After this incident, Fav and Sivrak spent some time together, along with other scouts, before returning to their respective homes. Sivrak formed a positive opinion of Fav.
She was later observed trailing scouts from the Rebel Alliance, always with a different ship (including the Zol-Uvena). Because these scouts were searching for potential safe havens, Fav's presence caused them to dismiss those worlds as unsafe, which eventually resulted in a shortage of Rebel safe havens.
She never launched an attack against any Rebel, and the Rebel Alliance was unable to find any proof of Imperial forces in the safe havens that Fav had identified. Nevertheless, the Alliance viewed her as a possible threat that needed to be addressed; and Lak Sivrak, an old acquaintance, was interested in questioning her.
The next time she was spotted, a team of Rebels attempted to meet with her and discuss a possible agreement. She was taken prisoner by slavers, most likely from the Mytaranor Slaving Council, and the Rebels made an effort to save her because of the information she possessed.
