The world is originally composed of countless races, each of which belongs to its own domain and is isolated by space. There is only one exception - Mitrand.
Miterland is composed of three main continents: Kaiya Continent, Hidden Blood Continent, and Trastolith Continent, as well as countless unknown islands. Here, all matter is composed of elements, and many animals and plants that are not found in other worlds are derived from this. Because there are many races and there are frequent struggles between races, the land and sea of Mitland are often stained red with blood, so other parallel worlds call it the blood-soaked holy land.
Originally, Mitland's war was only a local war. However, more than 10,000 years ago, manpower and material resources increased significantly, and the power of various races became stronger. Large-scale wars began to occur, with countless casualties and casualties, and the people were in dire straits. The economy of Mitlant declined for a time, and many races withdrew from the three main continents. Facing Mitlant, which was becoming increasingly unviable, the seven major races made an alliance with blood, made an agreement, lobbied and attacked other races, and restored peace to Mitlant. These seven major races are also highly respected and supported by people, and have become the nobles of Mitlan.
The 7 major races are gods, demons, elves, mermaids, orcs, humans, and vampires.
