This is a limited world with four races:
- Humans: rich in wisdom, but also cunning, good at planning in complex situations, and building huge kingdoms, which are full of power struggles and changes.
- Elf: light and flexible, naturally proficient in bows and arrows, living deep in the forest, guarding nature, and capable of defeating enemies with precise archery skills in war.
- Dwarves: Good at forging and united in character, they use their superb skills to build strong weapons and fortresses. Their kingdoms are mostly built deep in the mountains.
- Orcs: They are dull and savage, but they have a strong body. They rely on their powerful strength to gain a place on the continent, and their behavior is relatively cruel.
People of the same race will annex each other for resources and power, and when different races meet, they often aim to destroy each other. Each race will form different empires. Sometimes these empires will form alliances to jointly fight against foreign enemies; sometimes wars will break out due to conflicts of interest, all for the purpose of survival. There will be instability within the empire, and there will be reforms, independence movements, and even uprisings and revolutions.
At the beginning of the world, each of the four races had an immortal emperor. They were sent by God and possessed the characteristics of immortality. Their mission was to lead their own race to destroy the other three races. However, although they were powerful, they could also be killed.
