Ressa was a woman who existed in the era of the Galactic Republic. Prior to 3954 BBY, she served as the ruler of the world of Drezzi for a period. The Sith Empire, which was experiencing a resurgence, seized her planet during her time as queen, and Ressa's spouse was put to death. Nevertheless, Darth Nyriss, a Sith Lord, allowed her and her offspring to live. Ressa presented Nyriss with a hologram as a token of appreciation for the compassion shown. At a later point, Sechel, a Sith Pureblood, shared the story of the hologram with the Sith Lord Scourge as Sechel escorted Scourge to Nyriss's base on Dromund Kaas.
The 2011 book The Old Republic: Revan, authored by Drew Karpyshyn, included Ressa.
