According to the explanations in the story, the shape of the world is hard to understand and routes are difficult to imagine, so I drew a world map hoping it might serve as a reference for visualization.
It shows the general shape of the world and the approximate locations of the major cities.
The author doesn't have the skills to draw something like this, so there are places where the scale or the size of the continents might be a bit off — please bear with me.
Here's a brief explanation.
• Central Continent Divided into three parts by the Red Dragon Mountain Range.
The north is poor and rife with wars; the west is ruled by the
Humans make up the majority of the population.
• Demon Continent Demons are powerful and the land is poor.
Demon Kings reign in various regions.
The demon race makes up the majority of the population.
• Millis Continent The Great Forest lies to the north, the Millis Holy Country to the south.
Through the Great Forest and the Blue Dragon Mountain Range runs the Holy Sword Highway — a perfectly straight road where not a single monster appears.
The population is evenly split between humans and beast-race.
• Begaritt Continent Full of dungeons, with many areas that are abnormal in terms of magical power.
Monster strength is on par with the Demon Continent.
Various races live here. Almost all of them are adventurers or former adventurers.
• Heaven Continent There is flat land at an elevation of around 3,000 meters.
The Heaven race lives here.
