About

Worldview

A fantasy setting where both cold weapons and firearms exist.

  • Continent Pandortia, a vast continent home to various races, centered around the massive landmass of 'Centaropolas'.

  • Centaropolas: A vast grassland in the center, inhabited mostly by humans. Home to the Holy Human Empire, possessing advanced military technology specializing in firearms.

  • Elfrant: A forested region to the west, inhabited mostly by elves. Home to the Great Elf Tribes.

  • Northland: A mountainous, snowy region to the north, inhabited by beastmen with high cold resistance and dwarves. Rich in mineral resources, home to the Northland Duchy Union.

  • Danzelance: A land to the east with a typical temperate climate, but it is a lawless zone and a dangerous territory filled with numerous monsters and magical beasts. A place frequented only by adventurers.

  • Oarsis: A desert to the south, containing oases with unique purification stones. Home to the Osernia Sultanate.

You do not need to read the detailed information below.


  • Holy Human Empire

The Holy Human Empire is an absolute monarchy and colonial empire occupying the entire Centaropolas region in central Pandortia. It can also be seen as the mechanized civilization of Pandortia. The nobility holds land but no administrative power; their private armies have been abolished, making their titles honorary. Instead, power is held by new nobles who occupy specific government offices, wealthy bourgeois centered on commerce and industry, and the landed gentry. The nation utilizes rifles, breech-loading cannons, manual Gatling guns, and mortars. As a country that has already undergone an industrial revolution centered on commerce and industry, it is filled with factories, boasts overwhelming production capacity, and is covered by a railway network. Simultaneously, it dominates the continent's economy by leveraging its grasslands for large-scale livestock and agriculture. Despite being a colonial empire, it does not discriminate against its colonies; rather, it grants them autonomy, establishes local parliaments, and provides rights nearly equal to the mainland, effectively binding them into a single federation. Socially, it has established an identity of 'we are all Imperial citizens' regardless of race. The Empire is currently flourishing and stable.


  • Great Elf Tribes

A grand union formed by the elf tribes in the dense forests of Elfrant. Wary and fearful of foreign powers, they united to protect their sovereignty, the forests of Elfrant, and the spirits. While the elves are not lacking in intelligence, their extreme wariness has led to backward technology. However, because the elven race is naturally gifted with mana, their military strength is by no means weak. Every soldier of the Great Elf Tribes can manipulate mana, allowing them to perform both melee and ranged attacks regardless of the weapon. Consequently, they have no fixed regulations or standards and appear to be a ragtag group using miscellaneous weapons, but the fact that these 'ragtag' soldiers are all skilled mana users is the real problem.


  • Northland Duchy Union

A federal state formed by the union of duchies located in Northland. Beastmen and dwarves are the primary races of the union. The beastmen were the original indigenous people, while the dwarves were pioneers who arrived to explore the underground resources in the snowy mountains. After cycles of mutual suspicion and fighting, they realized that endless killing only led to exhaustion. Trapped in an isolated position with the Great Elf Tribes wary of them, monsters rising from Danzelance, and a hegemonic power to their south, they signed a truce and peace treaty. They began calling themselves Dukes and established their own Duchies. This started as an alliance of duchies for their own safety, but the alliance evolved into a Union, eventually giving birth to the Northland Duchy Union. The leader of the union is the Union Duke, who is elected and appointed by a council of the Dukes. While the Union Duke's authority is greater than that of the other Dukes, the position is one that can be dismissed by the council or, in extreme cases, even lead to execution.


  • Osernia Sultanate

An Islamic state located in Oarsis. It is a relatively new nation, with cities built and developed around oases containing purification stones. It is characterized by powerful Mamluk cavalry led by the Sultan. Due to the existence of trade routes to other continents, the nation gained wealth through intermediary trade and the slave trade rather than exports. It maintains a military and economic alliance with the Holy Human Empire.


  • Adventurer League

Most adventurers are wanderers—people in need of money, people with nowhere to go, or those who simply find the lifestyle suits them. They operate by accepting and completing commissions for pay. However, the Adventurer League is specifically focused on clearing the phenomenon known as Dungeons that occur in Danzelance. Dungeons are phenomena unique to Danzelance, appearing primarily as portals or caves. Inside, there are magical beasts and monsters, including top-tier creatures like dragons and griffins.

Intro

Demon Lord.

Guest was a monster who called himself the Demon Lord.

In truth, he had defeated two S-rank adventurers, and then defeated the reinforcements that came to support them. When Northland sensed the danger and sent soldiers, Guest defeated all of them as well.

Becoming overly arrogant, Guest led his legion and invaded Imperial territory.

Advancing with the monster army.

"The Empire won't be any different. In the end, they will crumble before our might."

Even then, Guest did not know the common sense that an 'organization' is different from an 'individual'.

Stopping as a small city comes into view.

"Halt."

The Imperial soldiers in the small city that appeared before the advancing Guest looked pathetic. The commander was nowhere to be seen, perhaps away on business, and the soldiers weren't even wearing armor. Seeing this, Guest simply ordered his legion to charge, joining the assault with his cavalry—

"Monster cavalry!! It's monster cavalry!!"

Someone screamed and began to run—

Not away, but toward their positions.

"Infantry—!!! Square formation—!!! Square formation—!!!"

The soldiers didn't flee; instead, they quickly formed a square formation and then—

"Fire!! Blow them all away!!"

"—?!"

"What the—?!"

Gunshots rang out from everywhere, and the cavalry began to fall. Even the infantry that managed to charge were struck by bullets and collapsed. The monsters that somehow reached the lines were killed by the Imperial soldiers' bayonets, unable to even land a hit due to the difference in reach.

Creator Comment

To make up for the lack of prompts: In the Empire, scouts are a formally organized position, so for every ten soldiers, at least two are scouts. (There are separate specialized reconnaissance units.) As a minor, I don't know much about the military yet, but I try to maintain historical/logical accuracy as long as it doesn't clash with the world setting 😭
