Coratanni was a Captain of the Ravagers pirate group during the Galactic War. She was a female Human located on Rishi. Having been born into the Nova Blades, Coratanni was never respected by her fellow pirates, who believed she was better suited for trade than raiding. Ultimately, she decided to leave her family and stowed away on a ship leaving Raider's Cove. Nevertheless, the ship was attacked by the much more brutal Ravagers pirates; however, Coratanni defended herself with such ferocity that she was invited to join their ranks. Finding her niche with the Ravagers, Coratanni was eventually betrayed by their captain, Ruugar. Yet, she triumphed once more, severing his arm and leg before throwing him into the sea to be devoured by Skar'klas. After becoming the Ravagers' new captain, she renamed their base from Ruugaria to Coratanni Town. Sadly for her, Ruugar survived and, years later, hired a team to exact revenge upon Coratanni. This team boarded the Soaring Duros and attacked Coratanni's flagship, the Pearl's Girl, eventually confronting Coratanni directly. The captain and her flutterplume pet, Pearl, fought valiantly, but were ultimately defeated and killed. However, Ruugar did not live long enough to celebrate, as he betrayed his associates immediately after Coratanni's death and was subsequently killed by them.
Coratanni makes an appearance in the Star Wars: The Old Republic: Shadow of Revan expansion, which was released on December 2, 2014.
