Kyrian of Thrace was the sole heir to the throne of Thrace. At age twenty, his uncle Zetes thrust him under the care of Julian of Macedon with threat of bodily harm if anything happened to his nephew.
At age twenty-two, he met and fell instantly in love with Theone, a women eight years his senior known for her renowned beauty. He disregarded friends and family in marrying her, a peddler of flesh, thus igniting his father's furor and leading to his disinheritance.
Although he lavished her with love and gifts, she betrayed him in every way possible. While Julian and he were away fighting the Romans, she welcomed them into their home and ultimately their marital bed. Shortly after Julian's curse and subsequent absence, Kyrian was caught in a trap set up by Theone. Valerius, his greatest enemy, beat and tortured him for four weeks, culminating in the ultimate act of betrayal: having sex with Theone right in front of him. Kyrian was then crucified and by the Roman army. During this moment his soul unleashed such a cry that all of Olympus heard. Artemis came to him and gave him one last act of vengeance against Theone if he vowed allegiance in exchange for becoming a Dark-Hunter.
In Night Pleasures, he woke up handcuffed to Amanda Devereaux. She helped him defeat the Daimon Desiderius and reclaim his soul from Artemis. He was human after that and married Amanda. In Seize the Night, they were killed by Daimons but Ash brought them back to life and made them immortal. They now have two children, Marissa and Nicholas Julian (NJ).
