The only difference between them is that they can control dragons or other larger beasts.
The planet is also divided into several small countries like the earth. Each country on this planet has its own mythical beast.
For example, the long dragon of the country of Yue is like the dragon in Chinese legend on earth. The long dragon of the country of Yue is very similar to the dragon of Chinese legend. They are both one long dragon. The same is true for several other countries, which have their own sacred beasts.
