Yue/Chronology

History
Yue, born as Aletia Galdea Vesperitio Avatarl, was the daughter of the rulers of the vampire nation Avatarl. At the age of twelve, she awakened the ability to automatically regenerate her body, as well as being able to manipulate mana. She trained under her uncle Dienleed and was eventually regarded as the most powerful magic caster of that era. She had become so strong that she managed to single handedly repel any army that attempted to invade her nation. Five years after she awakened her powers, her father, King Lambert, decided to abdicate the throne to his daughter in order to rule Avatarl. After becoming queen, Aletia noticed that her uncle became more formal and distant with her. Her subjects suspected that he was planning to claim the throne from her and begged her to execute him, but she refused to believe that he was capable of such acts. When she was 23 years old, Aletia met with emissaries of the Holy Church who wished to grant her the title of "Divine Oracle" as an act of friendship. It was then that her uncle and many of her subjects suddenly attacked and killed the members of the church, her loyal vassals, and even her parents. Her uncle had stabbed her through the heart as she was ordering his forces to stop their attack. She survived due to her ability to regenerate her body, but the mental shock from the attack caused to her to lose consciousness. She awoke to find that she had been imprisoned in a dark room with her uncle looking over her before she lost conscious again.

She was sealed inside a room that was located in the Great Orcus Labyrinth and was protected by two huge cyclops at the entrance. After being sealed for 300 years, she was saved by Hajime Nagumo and became his most trusted companion.
