Sharn was a high-ranking member of the Rebel Alliance's 61st Mobile Infantry. She served as second-in-command of the Braha'tok-class gunship Apailana's Promise, which escorted the 61st's CR90 corvette, Thunderstrike. In 3 ABY, Sharn attended a meeting where the Imperial defector Everi Chalis presented a new campaign for the 61st that targeted multiple Imperial installations, including Kuat Drive Yards. Sharn shook her head silently during the meeting's conversations and pledged the support of the gunship for the 61st when Chief Medic Von Geiz asked if she objected to a voice vote on the plan.

Sharn was a high-ranking member of the Rebel Alliance's 61st Mobile Infantry during the Galactic Civil War, being outranked by only a select few, including Captain Micha Evon, Lieutenant Sairgon, and Commander Paonu. She was also the second-in-command aboard the Braha'tok-class gunship Apailana's Promise, the escort to the company's CR90 corvette, the Thunderstrike. In 3 ABY, while both starships were receiving repairs on the planet Ankhural, Sharn attended a meeting held by First Sergeant Hazram Namir and rebel asset Everi Chalis, a former Imperial governor, where the latter pitched Operation Ringbreaker. The proposed campaign focused on soft Imperial targets along the Rimma Trade Route to divert forces from Kuat Drive Yards, which was the final target.
Chalis then allowed Sharn and the other attendees of the meeting to discuss her new plan. While the other attendees debated or raised questions, Sharn sat in the corner of the room, silently shaking her head. The Besalisk Gadren requested that Chalis leave and asked if Namir agreed with her plan. The First Sergeant confirmed that he did, and Gadren backed him. Chief Medic Von Geiz questioned whether a formal vote was required for approving Operation Ringbreaker, inquiring on Sharn's thoughts on having a voice vote instead. Sharn left the decision-making to Geiz and Namir, pledging the support of the Apailana's Promise. Ultimately, the subsequent vote was in favor of the operation.
Sharn shook her head quietly rather than engaging in the conversations regarding Operation Ringbreaker following its proposal. When Geiz asked if she supported a voice vote, Sharn pledged the support of the Apailana's Promise on the basis that the hosts of the meeting were in charge of the 61st and therefore the company's mission.
Sharn appeared in the 2015 novel Battlefront: Twilight Company, written by Alexander Freed.
