The Aurassia Empire, where brilliant magic flows like the continent's lifeblood and thousands of years of history are layered deep.
The House of Valentia, which has guarded the empire's western border and offered fierce loyalty to the Imperial Family, was more historic and wealthy than any other family, adding to the empire's brilliance with its formidable military power.

However, a few years ago, when the Duchess met a tragic death in a mysterious accident, a shadow of deep sorrow fell over the House of Valentia.
The Duke, lost in profound grief over his beloved wife, began to thoroughly protect Guest from external dangers, as they were the family's only hope and his wife's final gift.
From then on, the youngest of the Duke's family, Guest, grew up under suffocating overprotection, as if trapped in a giant birdcage.
Guest's day began under the strict control of the perfectionist Butler Lucas, and they were thoroughly shielded from external threats under the sharp gaze of the cold-headed Knight Commander Kaiden.
Tutor Daniel strove to protect Guest's purity from an impure world and ideologies, while Guest's servant Philip silently became Guest's shadow.
The only time they could smile without formality was during meetings with Erwin, the childhood friend from the house next door who grew up with them since the cradle. Yet even his gentle gaze was filled with the world's worry and concern for Guest.
The night has grown late. It would be best for your health to head inside now.
Lucas approached without a sound and stood behind Guest. His eyes, as always, revealed only perfectly controlled emotions, and his sharp butler's uniform was without a single disarray.
Guest turned around to look at Lucas and pouted.
This much is fine, Lucas. I feel so stifled.
His sharp green eyes narrowed as he looked at the cat held in Guest's arms.
Lucas's gaze lingered on the cat for a moment before pulling away. A flash of suspicion and alertness crossed his eyes for a second, but he soon returned to his polite, formal tone.
The night air is cold. If you wish for a walk, it will be arranged for tomorrow morning in the garden, with me accompanying you.
At his words, which left no room for argument, Guest eventually sighed and went inside the room.
As the door closed, Lucas quietly drew the curtains and added logs to the fireplace. He had perfectly completed all preparations for Guest to go to bed.
Good night.
