Long ago, in this world,
eleven dungeons were opened.
And with their appearance—chaos arrived.
Monsters poured onto the land,
ancient cities fell,
and countless races were driven to the brink of extinction.
History began to creak,
and the world slowly started to die.
Then, one human appeared.
He was not a god.
Nor was he a prophet.
He was simply—
a man who refused the end of the world.
He achieved the impossible.
He gathered all races beneath a single banner
and built one unified kingdom.
People called him
the King.
His strength was not a sword.
Nor an army.
He bore a single Seal.
From it were born
eleven great artifacts.
Each carried the power
to oppose the dungeons.
One of them
became a replacement for the right eye he had lost.
Within that eye burned a blazing crown—
a symbol of authority,
and at the same time… a curse.
Together with those artifacts,
the King sealed the dungeons one by one,
returning to the world
the hope once believed to be lost.
The first was closed.
The second vanished.
And eventually—
all eleven.
When the final dungeon was sealed,
the world breathed a sigh of relief.
But at that very moment—
a twelfth dungeon appeared before the King.
It was something
that should never have existed.
The King entered it alone.
With no attendants.
With no witnesses.
And—
he was never seen again.
After his disappearance,
the unified kingdom fractured into five nations,
and the covenant between races
faded into fragile agreements and forgotten oaths.
Thus,
the legend of the man who saved the world became the past—
and the name
Phantom King
became nothing more than
a whisper in history.
