Doors of the World

The **Doors of the World** is a citadel built in the northern part of the Topa Kingdom, which is a huge wall that prevents the invasion of demons from the Grameus Continent.

## Overview

In the northeastern region of Topa, there was a castle town called Tormeus that stood between the Topa Kingdom and the demons of Grameus. There was a natural bridge that was only 200 meters wide, but 30 kilometers long that connected the island to the continent. The country that called this island home was none other than the Topa Kingdom. To the northeast of Topa was another bridge, this one 100 meters wide and 40 kilometers long that joined them with the Grameus continent.

The Doors of the World is 20 meters high and span of 100 meters. Designed by the Imperial Japanese Army’s engineers, it was made out of stone and woodcut and processed by the dwarves, carried to the site by beastmen and the transport ships of the Imperial Japanese Navy, and built on-site by everyone. Using wood as the aggregate, they filled in with cement handcrafted by Japanese Kaneko Muneatsu himself after carefully rubbing the parts linking the stones with each other, making it one of the strongest and most durable structures in the world at the time. Furthermore, to combat corrosion from the waves, numerous boulders were thrown out into the ocean to push the sea back. As long as there weren’t many waves that touch the structure, it won’t corrode.

Maintaining this "Doors of the World" and preventing the invasion of demons on the Philades Continent can be called the mission of the Topa Kingdom and the significance of its existence. Its walls blocked off the natural bridge. They had repelled countless demon invasions. Topan soldiers were permanently stationed at the Doors of the World, and the castle town Tormeus was founded to support those soldiers.

However, in recent years, no great monsters have appeared, and the knights who protect them have relaxed their consciousness until Demon Lord Nosgorath is revived.

## Prehistory

Thousands of years ago, Demon Lord Nosgorath came from Grameus, the land of demons, leading a great army and wielding many types of magic. With it were legendary demon beasts, the Red Ogre, the Blue Ogre, the White Ogre, and Yellow Ogre, and an army comprised of various other demons. They had come to invade Topa and Philades Continent.

The Alliance of the Races struggled in vain to fight against the Demon Lord’s Army. Then they forced the Demon Lord’s Army off Rodenius, eventually going to Philades themselves. The Imperial Japanes, who called the Emissaries of the Sun God used their powerful magic to push the demons out of Philades and what is now the Topa Kingdom, all the way back to Grameus.

Two years later after the threat was neutralized, the Alliance of the Races with assist of the emissaries (Imperial Japanes) began the construction of a great wall called the Doors to the World across the end of the land of Topa. They completed it befor the God of the Sun called the emissaries back from this world. They then created both a castle town and a new kingdom. That kingdom would later become the Topa Kingdom.

## Chronology

At the beginning of the Second Demon Lord's invasion, over a hundred goblins on the ground headed invading to the Doors of the World from Grameus behind those two ogres, the Red Ogre and the Blue Ogre. With the land completely covered in demons, the swarm got closer and closer to the wall. The Demon Lord’s army had breached the Doors to the World. The Topa watch force had been wiped out. The Doors of the World was destroyed during the revival of the Demon Lord Nosgorath.

After the demon lord was exterminated by Japan in the **Battle of Topa Kingdom** known as Operation Momotarou and the Demon Lord’s army escaped back to Grameus, the reconstruction work has started on the Doors of the World with the support of Japan.
