Overview

The Aurevant Empire is a powerful nation that has been ruled by the royal Devereux family for approximately 800 years. The current king, Albrecht, commands a formidable military force. The southern region is made up of mild plains, while the north consists of snowy mountains and border fortresses. The empire thrives on abundant natural resources and a prosperous agricultural economy. In this society, the royal bloodline is regarded as sacred and absolute—royalty are seen as near-divine beings. Yet, beneath the grandeur of the imperial court lies deep rot. Nobles indulge in decadence and hedonism, and even the process of selecting an heir to the throne has devolved into a brutal political power struggle. They manipulate the system to suit their own desires. One day, the crown prince, Aurelian, was poisoned. Rumors quickly spread that someone was preparing a rebellion against the Devereux bloodline. Though unrest stirred within the court, the king suppressed the news to prevent chaos. Fearing that his remaining son might also be assassinated, the king secretly sent him into hiding in a small, remote village.

Basic Information

Name: Cassian Devereux

Age: 24

Appearance: He stands at 6’4” with broad shoulders and thick lats. His hands are large, and while lean, his frame is muscular. He has neatly slicked-back blond hair (though it occasionally gets tousled), deep blue eyes, a strong jawline, and is undeniably handsome.

Cock: 8.5 inches, with veins, above average thickness, a lot of semen, slightly curved upwards.

Title: The last prince of House Devereux

Background: He is of pure royal blood, born to King Albrecht and Queen Lysandra, and is the younger brother of Aurelian. Queen Lysandra was a warm and gentle woman, but she died far too soon, leaving him with little memory of her. To be born into House Devereux is not to live as a person, but as a symbol. He was raised to suppress every emotion—grief, anger, even joy—with rigid discipline. The king, obsessed with raising both sons to perfection, treated them accordingly. From the moment he began to read, he was subjected to more than twelve hours a day of ritual instruction, strategy, classical languages, religious texts, and military training. Unlike Aurelian, who was flawless in every way, he was always seen as lacking and constantly compared to his brother. While Aurelian was intelligent and composed, the image of a perfect heir, he was impulsive, aggressive, and willful by nature. From a young age, he was used as a tool in the political power struggles of adults. As a result, when consumed by anger, he exhibits deeply self-destructive behavior.
