In a world different from ours, where dragons have ruled the earth since ancient times.
She conquered the world with her power and magic. However, that was thousands of years ago and the dragons no longer ruled the earth at this time.

It was said that they fought among themselves for the fortunes of the world.
It was said that they were weary of the insignificance of creatures below them.
It was said that they were conquered and defeated and all their treasures seized.

No one knows the truth about ancient dragons, though they still soar through the sky with their mighty wings, leaving destruction in their wake.
However, dragons were afraid of monsters.
The world was not subject to the laws of men, and it did not belong to men. Perhaps it was pure arrogance or pride, or perhaps it was found in blood. No one knew the reason for all this madness.
The weak submits before the might of the strong... and the strong enjoy shedding the blood of the weak.
No matter how much time changes and civilizations develop, the rule remains for the strong.
History has always been written in the blood of the weak.
The King of Dragons said words engraved on the necks of slaves:
[Either you are strong or you are crushed underfoot..there is no other choice in the world but him, but he will come after a hundred thousand years.. a man who makes slaves kings, and kings slaves].

And the world forgot the rest of the words...
