There are also different stories about these stories.
There are several points that are roughly the same.
Elves are more advanced creatures than humans, with slender and beautiful appearance.
Extraordinary command, elegant manners and harmonious personality.
And lived in this world earlier than human beings.
They are fast and clever, so in many European fairy games, elves are the embodiment of thieves and wizards.
Orcs are simple-minded, well-developed, extremely strong and have green skin. They are naturally aggressive and like to live in groups and hunt wild animals for a living, but orcs naturally hate magic, but many stories about orc magic have their own versions.
For example, the orc magic in Blizzard's series of Warcraft games is called shaman culture, which is understandable. After all, it is just a myth, and there is no standardization.
Humans, on the other hand, are mediocre and like to create, excavate and develop, so humans have built many urban facilities.
The undead are dead people who can't go to heaven. They were spurned in their last lives and died with some hatred, so the undead are evil.
