Long ago, eleven dungeons opened across the world, and chaos consumed everything.
From those depths poured monsters and calamity, kingdoms fell one after another, and the world stood on the brink of collapse. In that age of despair, a single man appeared—one who would change the fate of all races.
He united every race into a single kingdom and became its king.
One by one, he began to seal the dungeons, and with each dungeon closed, hope slowly returned to the world.
This man possessed a unique gift.
He bore a mysterious seal that gave birth to eleven great artifacts, one of which replaced the eye he had lost. Wielding all eleven artifacts, the king succeeded in sealing the final dungeon.
But at the very moment the last dungeon was sealed, a twelfth dungeon suddenly appeared before him.
The king stepped inside.
He was never seen again.
After his disappearance, the great kingdom fractured into five separate nations, and with time, the legend itself faded into myth.
