❄️ The Empire of Arcadia ❄️

[ Worldview ]

A medieval romance fantasy empire where the Imperial Family and the four Grand Duchies coexist. The Imperial Family governs the center, while the North, South, East, and West are ruled by their respective Grand Duchies. The Grand Duchies possess independent military and governing powers, and the social hierarchy between nobles and commoners is strict. Legends about magic, magical beasts, and ancient bloodlines exist.

[ Social Hierarchy ]

Imperial Family > Direct Bloodline of Grand Duke > Duke > Marquis > Count > Viscount > Baron > Commoner.

The direct bloodline of the Grand Dukes holds the highest authority after the Imperial Family. Marriages among nobles are often for the benefit of the family and political alliances, and marriage with commoners is socially taboo. Most servants are of commoner origin, employed by noble families for their livelihood.

[ Northern Grand Duchy of Edelhardt ]

The northernmost frozen region of the empire. It snows for more than half the year, and magical beasts inhabit the Black Mountains to the north. The Edelhardt family has been a prestigious military family guarding the northern borders for centuries, commanding the Northern Knights, said to be the strongest in the empire. The family crest is a black wolf with a silver moon behind it.

[ Grand Ducal Castle of Edelhardt ]

A massive black stone castle built on a snow-covered cliff outside Belkheim, the capital of the North. It consists of high spires, thick walls, and endless corridors. The interior is decorated with black marble and silver accents, and in the harsh winter, the entire castle is engulfed in blizzards.

[ The Wolf's Bloodline ]

Rumors have long circulated that the Edelhardt family carries the blood of wolves. According to legend, the first Grand Duke made a blood pact with a black wolf of the snowfields to defeat the magical beasts of the North. Direct bloodlines are known to possess extraordinary senses and physical abilities, and it is said that wolf howls can be heard from the Grand Ducal Castle on nights with a full moon. The family remains silent on the truth of these rumors.

[ The Black Spire ]

An ancient black stone tower located at the northern end of the Edelhardt Grand Ducal Castle. Only direct bloodlines of the family and a select few confidants can enter, and access by outsiders is strictly forbidden. It contains windowless rooms sealed by thick iron doors and bars. Rumors say that on nights with a full moon, the sound of dragging chains and beastly howls can be heard from deep within the tower. What happens there is kept a strict secret.

[ Western Grand Duchy of Valterion ]

A temperate and prosperous region in the western part of the empire. It controls major trade ports and commercial cities, exerting strong influence over the Imperial Family through its vast wealth and diplomatic power. The family crest is a white snake entwined with a golden rose. It has a long-standing political rivalry with the Northern Edelhardt family.

[ Grand Ducal Castle of Valterion ]

A magnificent Grand Ducal Castle located in Servian, the capital of the West. It is famous for its white marble, gold decorations, large glass windows, and beautiful gardens. It features a greenhouse where flowers bloom year-round and a large banquet hall, often hosting social gatherings and political meetings of nobles.

[ Power of the Grand Duchies ]

Each Grand Duchy possesses its own knights and army. Entering another Grand Duchy's territory with armed forces without permission is considered an invasion and can lead to war between the Grand Duchies. The Imperial Family maintains a balance of power among the four Grand Duchies and mediates disputes.

[ Nobles and Servants ]

Noble families have a butler, head lady-in-waiting, personal attendant, personal maid, and general servants. Personal maids are responsible for their specific master's clothing, meals, bedroom, and daily life, and can enter the master's private spaces. While servants are not legally the property of nobles, the difference in status and power often makes it difficult for them to refuse their master's orders.

[ Northern Magical Beasts ]

Various magical beasts inhabit the Black Mountains and deep coniferous forests. Northern magical beasts have adapted to the harsh cold, possessing strong bodies and special abilities. Northern Knights and specialized hunters are deployed in areas where magical beasts frequently appear.

[ Frost Wolf ]

A rare wolf-like magical beast that inhabits the Northern Black Mountains and ancient coniferous forests. It is larger than a normal wolf, with silvery-white fur and ice-blue eyes. It is wary of humans and rarely shows itself. Ancient legends say that the Frost Wolf is connected to the wolf bloodline of the Edelhardt family.

[ Imperial Forbidden Archives ]

A secret archive located in the basement of the Imperial Palace. It stores records of history before the empire's founding and the bloodlines of each Grand Duchy. In particular, some documents related to the origin of the Edelhardt family have been sealed for centuries and can only be accessed by a very small number of individuals within the Imperial Family.

[ Imperial Power ]

The Emperor is the supreme ruler of the empire, with the authority to mediate disputes between the Grand Duchies and enforce imperial laws. Disobeying the Imperial Family's orders can be considered treason. Within the Imperial Family, there is a complex power structure involving the Empress Dowager, Imperial family members, and high-ranking nobles, in addition to the Emperor.

[ Current State of the Empire ]

The authority of the Imperial Family is weakening, leading to intensified conflicts between the Grand Duchies. The Northern Edelhardt family is expanding its influence through military power, while the Western Valterion family is doing so through wealth and diplomacy. The confrontation between these two families is considered a source of political instability for the entire empire. Meanwhile, the movements of magical beasts in the North are becoming increasingly unusual, and legends of the ancient wolf bloodline are once again being whispered among the people.
