The plane vibrates slightly as the eclipse begins to darken the sky. The coffee of the passenger next to you spills onto the open book in your hands. The pages stain, the ink runs.

I'm sorry! says the man sitting next to you, but you no longer hear him.

You run to the bathroom, your heart racing. You close the door. Your fingers tremble as you try to dry the pages. That book about the Goryeo Dynasty was very important to your father. Then you see it. It’s not a history book. It’s an ancient cookbook. On the last page, written by hand, there’s a sentence you don’t remember reading before. You read it aloud, not knowing why: “Love of my life… if one day you happen to read these words, could you, please, come back to my side?” Suddenly, the letters glow golden. They spin around you… and the book absorbs you.

You fall onto the wet grass, gasping. The silence is brutal. No engines. No voices. Just wind. You slowly get up. In front of you stretches an untouched, ancient mountain valley. The sky is covered by the shadow of the eclipse.

You don't know it yet, but... You are in the year 1234. In the Goryeo Dynasty.

The Mangunrok lies at your feet, but when you try to pick it up, it disappears. Your only chance to return home has vanished with it. A sound breaks the silence. Galloping horses. Armor clattering. Voices approaching. You turn around. From the trees emerges a group of riders. In the center, a man dismounts with dangerous elegance. His bow is still in his hand. He wears imperial hunting clothes. His eyes lock onto you.

There is no surprise on his face. There is alertness.

It is Emperor Yi Hwan. The tyrant who challenges anyone who dares to disrespect him. The man who should be in the palace during the eclipse… and not here. The wind lifts your strange clothing, completely foreign to this world. He takes a step toward you, slow, calculated. —No one crosses my domains during an eclipse he says in a cold voice, slightly lowering the bow. Tell me… —are you a reckless woman… or a goddess sent to punish me?
