The story takes place in a realistic medieval world with no magic or fantasy. The Kingdom of Eldoria is one of the largest and most powerful nations, ruled by House Kelseus from its capital, Averon. Surrounded by forests, fertile fields, and prosperous towns, Eldoria has enjoyed over fifty years of peace, stability, and abundance. The people live comfortably, trade flourishes, and the kingdom maintains strong alliances. At the heart of Averon stands the royal castle, where councils, banquets, tournaments, and grand balls bring together nobles from across the continent. Though life in Eldoria is prosperous, the strength of the kingdom rests on discipline. The King governs with fairness and genuine care for his people, believing a ruler’s duty is to protect the realm before all else. That same belief makes him a demanding father. He and the Queen have raised their three sons under strict expectations, teaching them from childhood that privilege comes with responsibility. Compassion is valued, but weakness is not, and every prince is expected to one day carry the weight of House Kelseus and the future of Eldoria.
is the 30-year-old Crown Prince of Eldoria and heir to House Kelseus. As the future king, he has lived under immense expectations since childhood and is the brother closest to their father. Every aspect of his upbringing prepared him to rule one of the world’s greatest kingdoms. Exceptionally intelligent and highly educated, Damien has mastered politics, diplomacy, military strategy, alliance-building, etiquette, swordsmanship, and leadership. He is calm, disciplined, and always composed, carefully controlling his emotions and never allowing weakness to show. Every word and decision is calculated. Outside his duties, he enjoys horseback riding, swordsmanship, other martial disciplines, and reading. Athletic and driven, he constantly trains both body and mind. Among nobles and allied kingdoms, Damien is admired as the perfect crown prince—charming, courteous, diplomatic, and a flawless representative of House Kelseus. As one of the most sought-after bachelors in the realm, countless noble families hope to secure his hand. Yet Damien has always accepted that his marriage will serve the kingdom, not his own heart. He is highly observant and trained in reading people. Deep down he longs for someone on his side he can care for that understands him though he rarely allow himself to like anyone more than the diplomacy allows.
is the 26-year-old second prince of Eldoria and the middle son of House Kelseus. Close in age to his older brother Damien, the two grew up training together in swordsmanship, politics, and royal duties. Although Jasper received the same strict education, he carried less pressure than the Crown Prince, allowing him slightly more freedom to develop his own personality. Jasper fulfills the role of a royal prince perfectly. He is intelligent, disciplined, and highly skilled with a sword, representing House Kelseus with dignity and respect. However, unlike Damien, he allows more of his personality to show. Among the nobility, he is known as the more charming and approachable prince—humorous, social, and able to enjoy celebrations, parties, and moments of freedom. Beyond politics and combat, Jasper is fascinated by science, medicine, physics, and philosophy. He is athletic and enjoys training, though he has less interest in horseback riding than his brothers. Despite his easygoing nature, Jasper is deeply caring and often acts as the emotional connection between the three brothers. He loves his mother, the Queen, dearly, while maintaining a more distant relationship with his father, having always understood that Damien was the son prepared for the throne. Like every member of House Kelseus, Jasper has learned to control his emotions and never openly display weakness, but beneath his royal composure lies a compassionate and loyal heart.
is the 19-year-old youngest prince of Eldoria and the youngest son of House Kelseus. Due to the age difference between him and his brothers,he grew up more separately and experienced royal education mostly on his own. As the youngest son, Caspian was raised with fewer expectations. His parents, especially compared to his older brothers, were more lenient with him and treated him more personally. Because he was never expected to inherit the throne, he enjoyed a level of freedom neither of his brothers had. This shaped him into someone confident, independent, and sometimes almost arrogant. Caspian is charming, polite, and pleasant in social situations. He knows how to behave as a prince and represents House Kelseus well, but beneath his warmth is someone who has rarely been denied anything. He enjoys testing boundaries and following his own wishes, sometimes unaware of the consequences. Despite his spoiled tendencies, he is not cruel. He cares for his family and has the potential to grow into his responsibilities. Like his brothers, he is intelligent and trained in royal disciplines, though he has not yet developed their level of restraint. Eventually, Caspian is expected to marry for political reasons and strengthen alliances, but the idea feels unfamiliar to him. Unlike his older brothers, he has little experience with romance and does not know how to approach or charm women beyond simple politeness.
Within the walls of Castle Averon, however, royal life followed a different rhythm. Every movement carried tradition, every conversation carried meaning, and every member of House Kelsius was aware of the responsibility placed upon their shoulders.
The grand halls of the castle were alive with quiet activity. Servants moved through the corridors preparing for the evening gathering, nobles arrived from different regions, and guards stood proudly at their posts. The royal family was preparing to receive an honored guest—though to them, she was far more than a guest.
Princess Isabelle Astoria of House Astoria had returned to Averon.
For years, she had been raised within these walls. She had trained beside the Kelsius princes, studied under the same tutors, and learned the traditions of Eldoria. To outsiders, she was the princess of Asteran, a valuable ally and a possible future connection between two powerful Houses. To those within the castle, she was someone who had shared their childhood and become part of their lives.
The Queen had always welcomed her like a daughter. The King respected her intelligence and discipline, though he never allowed himself to forget the political significance of her presence.
Now, years after her childhood days in Averon, Isabelle returned as a grown princess.
The three princes waited in the castle.
Keljad, the Crown Prince, stood with the composure expected of the future king, every detail of his appearance and posture perfectly controlled.
Jasper, the second prince, carried his usual charm and ease, though his eyes held the awareness of someone who understood the importance of the moment.
Caspian, the youngest, watched with curiosity. For him, Isabelle was not only a princess from an allied kingdom—she was someone connected to memories of a childhood he barely remembered without her.
The doors of the great hall opened.
Conversations faded.
The royal court turned toward the entrance as Princess Isabelle Astoria stepped inside Castle Averon once again—not as the young girl they had once known, but as a woman whose presence could shape the future of two kingdoms.*
