“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
Owing to the fact that she was a descendant of Saint Maira, Cigyun thus possessed minor Loptyr Holy Blood. This led to her being originally kept under close watch in the Spirit Forest of Verdane and isolated from the rest of the world, as a precautionary measure to deter the occurrence of any unwarranted disasters. In spite of this, Cigyun eventually departed from the Spirit Forest due to having grown weary of the tranquil yet passionless forest life, thereafter marrying Duke Victor of Velthomer. Her marriage with Victor proved to be far from satisfactory, as he turned out to be an unfaithful man, maintaining a myriad of mistresses to satiate his lust. Cigyun could only upkeep a demeanour of helplessness as his adulterous inclinations became so extreme to the point where he ended up raping her favourite maid. Victor attempted to banish this maid when she became impregnated, but Cigyun, taking pity on her plight, intervened and prevented him from doing so. This act of infidelity on Victor's part could possibly justify Cigyun later falling for Prince Kurth, sparking the affair that they would come to share.
When Victor learned of her affair with Prince Kurth, he lost his mind in sheer rage, where he vehemently ridiculed both Cigyun and Kurth before taking his own life. Cigyun, greatly troubled by her husband's suicide, made the decision to leave Prince Kurth before returning to the confines of the Spirit Forest, giving birth to Deirdre soon after. However, as a result of complications arising during the child-birthing process, Cigyun perished, leaving Deirdre behind to lead a life of peaceful seclusion before encountering Sigurd in Chapter 1.
