This World—Arcatia.

The vast land is divided by six major powers.

The Kingdom, the Demons, the Elves, the Merchant City Union, the Dragons, and Guest's Mansion Faction.

Guest navigates this world of war alongside 27 members of different races and modern weaponry.

【1st Faction】 Guest's Mansion

Atop a cliff sandwiched between the mountains and the sea, there exists a single mansion isolated from the outside world.

It claims a territory with a radius of 28km from the center of the mansion.

• The ground within the 27km radius is flat terrain.
• The 27km perimeter is constantly protected by a high-voltage laser grid that instantly slices through flesh upon contact.
• A barbed-wire fence is laid along the 28km perimeter.
• The forest outside the territory is home to ferocious beasts, serving as a third wall.

The mansion is an independent "closed civilization" possessing powerful magical barriers, advanced autonomous defense mechanisms, and modern weaponry non-existent in other factions. Internally, food, energy, and technology are all self-sufficient, allowing it to persist without depending on the outside world.

Under the master Guest, 27 hand-picked loyal retainers gather. Each is an elite with exceptional knowledge and unique abilities, swearing absolute loyalty.

The mansion is equipped with all kinds of firearms, including assault rifles, sniper rifles, machine guns, pistols, and grenades. It possesses the knowledge, skills, and resources to create tanks, fighter jets, bombers, destroyers, Intercontinental Ballistic Missiles (ICBMs), surface-to-air missiles, and military satellites. It is also possible to create these to further enrich the faction.

【2nd Faction】 The Human Kingdom

Located slightly north of the continent's center is the Human Kingdom. Ruled by Queen Alicia, this country prides itself on its stone walls and knightly orders, uniting the people under a feudal system. The technology level is equivalent to medieval Europe, where swords and magic are the stars of the battlefield. They fight using armor, spears, and bows. Humans possess unity and overwhelming numbers.

The population of the Kingdom is 2.5 million.

【3rd Faction】 The Demon King's Castle

The Demon Faction rules the wilderness and volcanic regions of the southern continent. Under the reign of terror of Demon King Nephia, demi-humans and monsters stir according to a strict hierarchy. Her ambition is limitless, and wars with the Kingdom have been repeated many times. They possess excellent individual strength, superior physiques, and cruelty. Their strength also lies in having aerial forces like wyverns.

The population of the Demons is 800,000.

【4th Faction】 The Elven Territory

The deep forest region to the west is the Elven domain. Under the leader Emeria, they are a reclusive tribe that continues to protect thousands of years of history and the wisdom of natural magic. They are long-lived and master magic. They live in the forest and have high pride.

The population of the Elves is 300,000.

【5th Faction】 The Merchant City Union Territory

Located in the center of Arcatia, the economic and commercial hub consists of port cities scattered along the eastern coast. Led by Chairman Vincent, the Merchant City Union uses money and information as weapons, siding with no faction but trading with all. It is a city that unites commerce and the economy.

The population of the Merchant City Union is approximately 270,000.

【6th Faction】 The Dragon Territory

Beyond the mountain range in the northeast of the continent, above the sea of clouds, lies the nest of the Dragons. The Dragons are the strongest race in terms of individual combat capability.

The population of the Dragons is 2,700.
