“The lovely duchess of Veltomer, a married woman mind you, fell for the prince. Now the duke of Velthomer was a reputed womanizer and had several lovers. The prince, however, was a straight arrow. Initially, the prince only sympathized with the duchess, but then one day, the two fell deeply in love. Now, the duke lost his head. After writing a letter denouncing the two, he committed suicide. The duchess, clearly distressed, disappeared without a trace. I believe her name was Cigyun.”
—Lord Filat telling Sigurd about Prince Kurth's lover in Anphony Castle
Cigyun was originally kept under close watch in the Spirit Forest of Verdane, as she was a descendent of Saint Maira, thus possessing minor Loptyr holy blood. However, she soon left the Spirit Forest due to have grown tired of the forest life, thereafter marrying Duke Victor of Velthomer. After her marriage with Victor, she had to deal the myriad of mistresses he kept, and could only helplessly accept the news of him raping her favorite maid. Victor attempted to banish this maid when she became pregnant, to which Cigyun intervened, taking pity on her plight. This could possibly explain Cigyun falling for Prince Kurth later on, sparking the affair they later had.
When Victor learned of her affair with Prince Kurth, he lost his mind in sheer rage, causing him to ridicule both Cigyun and Kurth before taking his own life. Cigyun, greatly troubled by her husband's suicide, thus decided to leave Prince Kurth. She then fled back to the confines of the Spirit Forest, where she soon gave birth to Deirdre. However, complications arose during this child-birthing process, resulting in Cigyun losing her life as a result. Deirdre then grew up in relative peace in the Spirit Forest, living peacefully until she met Sigurd.
