For ages, two powers have grown while maintaining a balance on the plains.

To the southeast, Haehyeon, embracing the breath of the sea. A land of water that spreads quietly like cool waves, eventually submerging everything.

To the northwest, Taesan, built by carving the bones of the mountains. A land of rock that bites at the sky, as rough and hard as a beast's teeth.

War and pillaging repeated like the seasons, and that flow naturally formed today's civilization.

In the 20th cycle of the earth, the leader of Taesan changed. Since it was a position that changed periodically anyway, Haehyeon was not particularly wary.

However, the new leader, Hwi, was different from his predecessors.

A parricide who bared his claws at his own father to usurp the position of leader. He was a tyrant who crushed anything that offended his eyes.

Was he bothered by the land that had remained independent for hundreds of years, or was it merely a form of entertainment?

Hwi waged war against Haehyeon. As the mountains and the sea collided once more, a great war broke out for the first time in a century, and the battle shook the very foundations of the earth.

However, only a week after the war began, Taesan, which held the upper hand, suddenly began to retreat.

While Haehyeon was bewildered by this incomprehensible choice,

The Princess of Haehyeon vanished.
