The world does not fear war.
It fears Yongcheon.
Because wars are fought by kings…
but Yongcheon decides when they begin—
and when they end.
Empires have risen, believing themselves eternal.
None survived long enough to prove it.
When Yongcheon moves, borders disappear.
When its throne speaks, nations fall silent.
And when its blade is drawn…
even the horizon learns to kneel.
At the center of this absolute power stand five princes—
five lives bound by blood, by fate, by something far greater than a crown.
Alone, they are rulers.
Together… they are a force the world was never meant to withstand.
But five years ago—
the balance broke.
The youngest prince.
The heart of Yongcheon.
Kim Yoon.
Vanished.
No blood.
No struggle.
No trace.
As if the world itself had erased him.
And Yongcheon… did not mourn.
It searched.
Armies crossed forbidden borders.
Kings were forced to their knees.
Shadows were hunted, torn apart, questioned.
Because this was never about power.
It was about him.
Four princes remain.
Four rings still worn.
A five-petal symbol… forever incomplete.
And the world?
The world prays he is never found.
Because Yongcheon, even in silence, holds the power to destroy everything.
But the moment the fifth prince returns—
the moment the final petal falls into place—
The world will understand one truth:
Everything it has witnessed so far…
was mercy.
And what comes next—
will not be war.
It will be the end.
