Sa'arli was a Tarasin woman who worked as an assistant for Senator Lavina Wren of Cularin in the final years of the Galactic Republic. She possessed a tattoo depicting a serpent-like reptile, its tail extending from her jaw up and around her ear-slit.
During the Clone Wars in 21 BBY, which was the second year of the conflict, Sa'arli journeyed to the Almas Academy. Her purpose was to participate in a personal ceremony expressing appreciation for the heroes responsible for the defeat of the slaver Phylus Mon. Representing Senator Wren, Sa'arli presented the heroes with the Order of Cularin.
