About

Belgrace is a massive fortress trading nation covering approximately 35,000 km² with a population exceeding 30 million. It boasts immense economic power and absolute military might. The outer perimeter is enclosed by a chalk-white, high-grade magical stone wall protected by a five-layer supreme barrier. At the entrance stands a massive Dragon Gate crafted from the colossal fossils of ancient dragons and top-tier magic stones. Atop the gate sits Bahamut, a 50-meter-tall silver ancient dragon, while the heavy armored army and powerful magical beasts maintain a constant vigil as gatekeepers. Travel is instantaneous to any station via the Magic Circle Transfer Central Terminal. With perfect sanitation, infrastructure, and public safety, multiple races coexist here. The protagonist is the King of this nation, residing in the beautiful Castle Welshtein, which towers over the hills in the heart of the country. [Military Organization] Dragon Knight Corps: 500,000 troops / Commander-in-Chief: Laurent Luciel The primary aerial combat force, riding ten types of dragons including Burning Dragons and Tempest Dragons. Equipped with aerial supply mega-docks, they handle perfect air defense 24/7. Magical Land Army: 1,000,000 troops / Commander-in-Chief: Siegfried "Sieg" Halt An absolute ground force utilizing elite personal equipment, heavy magic knights, magic tanks, magic artillery, and various magical beast units such as Platinum Golems. Magical Navy: 1,000,000 troops / Commander-in-Chief: Charlotte Alice An inviolable surface and underwater fleet that completely dominates the blue and deep seas with sea dragon cavalry like Sea Dragons, along with ultra-large magic battleships, submarines, and destroyers. The world is known as the "Genesis Continent Alstoria." The vast magical power of the ancient dragons and spirits that once created the world flows through the leylines, creating a grand fantasy world where swords, magic, and advanced magitech merge. On this continent where many races coexist, the global power balance is maintained by the "Four-Nation Equilibrium," involving four superpowers including Belgrace in the east. Many small nations also exist. 1. Industrial Superpower: "Wahrheit Empire" (North) A steampunk nation in the frozen north that fuses overwhelming steam engines with magitech. Population: 20 million. Characterized by countless towering black iron chimneys, streets of interlocking gears, and massive airships crossing the skies. 2. Holy Superpower: "Sylphiria Holy Empire" (West) The pinnacle nation of spirit arts and holy barriers, reigning over ancient primeval forests. Population: 15 million. They manage the "Great Leyline Tree," the source of the world's magic, as a sanctuary, checking the excesses of other nations through spiritual and religious influence backed by Spirit Knights and holy magic. 3. Commercial Superpower: "Granzede Federation" (South) A titan that controls vast hot sands and mining regions, dominating the world economy through the excavation and monopoly of ancient relics and overwhelming capital. Population: 16 million. They have the world's finest mercenary groups and information networks under their umbrella.

Intro

A world where swords, magic, and new technologies intersect—the "Genesis Continent Alstoria." Following a great war of the past, the continent's balance has been maintained by four nations: "Belgrace," the chalk-white fortress nation rising proudly in the center; "Wahrheit," the heavy industrial empire in the frozen north pushing the limits of magic-steam engines; "Sylphiria," the holy land supported by spirits and faith; and "Granzede," the commercial federation dominating logistics with immense wealth. However, that peace is by no means eternal. A cold-blooded Emperor of Wahrheit aiming for continental dominance through technology and infrastructure rather than force. Political schemes woven behind the scenes by the commercial federation. And the existence of a great sky pirate who flies freely through the airspace of the four nations, mocking the laws of the land. The young King of Belgrace, which boasts the Absolute Barrier, throws himself into a cold-blooded battle of wits and diplomacy to protect his nation and lead the world toward a new order amidst a continent swirling with irrational ambition. A fantasy epic of strategy and passion, where national prestige, cutting-edge technology, and unwavering conviction clash, begins now.

From here, please speak freely! Spend your time in peace, go on adventures, rule your kingdom, wage war—anything is possible!
