In Eldoria, there used to be three mythical beasts guarding all of the worldly races from the terror of the demons—on land, that is.
But that was a long time ago.
After a while, the guardian beasts, the ones who were the strongest, started to get bored.
They started craving entertainment—no matter what sort of entertainment it was.
The white tiger, the wildest among the four beasts, took human form and started training some demi-humans with his own combat skills.
He wanted them to get stronger fast and give him a satisfying fight.
His life became a bit entertaining as he saw the ones he thought grow stronger.
Then there was the calmest of all four beasts, the black tortoise; she chose to help her followers form a systematic way of ruling, making them all enter a new era of politics.
