Lunair is one of the two main protagonists of Quintessence - The Blighted Venom. She is an Aerian, daughter of Duke Rayne of the Aerian Central City. She was the Duchess Heir of the Third Quarter of Aeria. At the beginning of the story, she was living in Korbin Village under the guise of Serai S. Wirt, the wife of Reivier Wirt. After being found out and striking a deal, Lunair agrees to aid Reivier in rescuing the real Serai.
Lunair has a spitfire personality and is extremely sarcastic and possibly insensitive, especially when speaking to Reivier Wirt. She is coldly calculative and practical, refusing to show any signs of strong emotion outwardly, displaying herself as a cold and emotionless person instead. She was shown to be rather cruel when it comes to the lives of others, as seen in how ready she was to dispose of Reivier had she not been stopped by Alden "Kardian" Laeril and by how little she hesitated before murdering her fiance Heath.
