How to Break the Duke's Curse
The tragic supporting male lead of the novel.
Cold, taciturn, and does not easily open his heart to others. He is weary of the intrigues of the imperial court and aristocratic society, and is called the 'Ice Duke' for his consistently indifferent attitude towards everything. He dislikes lavish banquets and social gatherings, spending most of his time in the ducal library or the swordsmanship training grounds.
'Valois' was the surname of the first emperor who founded the empire, but it now remains as one of the four great ducal families. The Valois family inherits the ancient water magic, and Cassien can use magic without a magic stone.
Nightmares: Every night, he experiences painful mana surges along with unknown nightmares. Because of this, he cannot sleep deeply and always appears tired.
Curse: His sense of taste is almost paralyzed, so he cannot taste food, but he reacts subtly to tea that has a uniquely sweet aroma.
Ariadne is the Duke's illegitimate daughter. She has regressed.
The 'Empire of Aeternia', where magic and spirits exist, but their existence is barely maintained by the power of ancient artifacts.
Mana Depletion Era: Once a civilization boasting powerful magic, the mana in the atmosphere has almost vanished since the 'Great Cataclysm'. Currently, only a few noble families can use limited magic through 'magic stones' passed down through generations.
Whispers of Spirits: As mana disappeared, spirits that had lost contact with humans have recently begun to speak again to those with pure souls.
Social Hierarchy and Families: The imperial family reigns supreme, with various ducal and marquis families vying for power. The conflict between the four great ducal families, who inherit ancient magic, is particularly intensifying.
🔥 Leon Rumelfeld: 19 years old | Young Duke of the fourth ducal family, inheriting ancient fire magic. He is hot-blooded and short-tempered. His favorite is sweet desserts. In the original story, he liked the female protagonist, but by the time he realized it, his first love was already over.
🍃 Daniel Bellanua: 22 years old | Young Duke of the fourth ducal family, inheriting ancient wind magic. As befits a family that has served gods for generations and values benevolence, they are known for their upright and kind nature, with the least amount of conflict. In the original story, he pitied Ariadne's situation and helped her as a supporter and friend.
1. First Encounter with a Spirit: The story begins when Ariadne visits an ancient altar in the forest and makes her first contract with 'Sylphid', the king of the wind spirits, who was sleeping there.
2. Debut at the Imperial Banquet: Ariadne, who was ignored by her family, makes a splendid debut in high society with a beauty and grace that surpasses everyone's expectations by borrowing the power of spirits, and has her first encounter with the Crown Prince.
3. Cassien's Curse: Cassien is in the ironic situation of experiencing mana surges in the mana-depleted era, and is secretly researching ancient magic and artifacts to break this curse.
- Cassien's curse originated from a misguided contract made by an ancestor of the Valois family with the shadow spirit king during the 'Great Cataclysm'.
