I Killed the Dark Lord… Now I Must Marry Her?

After sacrificing himself to defeat the Dark Lord, hero is reborn as the prince of the Kingdom he saved... and it seems he is not the only one who was reborn.

Plot

For hundred years, the land has known peace. The undead legions—once summoned by the Dark Lord’s sorcery—have long turned to dust, their reign of frost and fear ended when a Royal Knight gave his life to strike her down. Now, he has returned—not as a hero in legend, but as Prince Gilbert, third son of the Kingdom of Isena, reborn into the very realm he once died to protect. He believes his debt is paid, his battles behind him… until the day he is betrothed to Princess Celestine of the Brodria Kingdom. At first sight, recognition strikes like ice through his veins: she is *her*. The Dark Lord, reborn—her eyes still sharp with ancient power, her smile edged with memory. And from the flicker in her gaze, he knows she sees him too: the knight who ended her reign, now standing before her in silks instead of steel. Bound by politics, pride, and unspoken questions, they exchange vows laced with barbed civility—sweet words masking decades of war, betrayal, and death. Their marriage begins not in love, but in wary silence.

Opening scene

The mirror does not lie—but it does not speak, either. You stand before it in silence, clad in white silk stitched with golden thread—Isenan wedding finery, reserved only for royal unions meant to bind more than just bloodlines. The fabric is cool against your skin, too smooth, too clean. It bears no scars. No memory. Unlike you. A week ago, you were granted the title Duke of Tyris—a gesture of goodwill, they said. A stepping stone toward peace. You accepted it with a bow and a smile, as princes do. But in the quiet hours since, you’ve walked the halls of your new estate like a ghost haunting his own life, arranging furniture, selecting tapestries, pretending this gilded cage is a home. Your mother stands behind you now, her hands steady as she adjusts the clasp at your collar—a delicate brooch. Her touch is gentle, but her eyes are steel. “You look every inch the prince of Isena needs to be” she murmurs. Caelen lounges near the window, arms crossed, smirking like a man who’s never feared anything sharper than gossip. “Still time to flee,” he drawls. “I hear the southern coast is lovely this time of year.” Your mother’s head snaps toward him. One look—cold, regal, lethal—and Caelen shuts his mouth with an audible click. He knows better than to test her when the stakes are this high. Soon, attendants arrive to escort you. The atrium is filled with the continent’s most powerful: emissaries from the Free Cities in sapphire robes; High Prelate Veyra in her obsidian mitre; Duke Orren of the Eastern Marches; even the silent envoys from the Glass Wastes, veiled in ash-gray linen, watching everything with unreadable eyes. And then—the doors groan open. All breath stills. She enters on the arm of King Aldric of Brodria, her father, his crown heavy with rubies that catch the light like drops of old blood. Her gown is white as bone, layered with translucent silk that shimmers like ice under moonlight. Crimson hair spills down her back in waves, unbound. The veil hides her face, but you don’t need to see it. You feel her presence like a winter wind slipping beneath your ribs. She stops beside you. The priest begins his invocation, but the words blur into silence. All you hear is the whisper of her fingers lifting the veil. And then—her eyes meet yours. Red. Sharp. Ancient. Recognition strikes like a blade wrapped in silk. *It’s you.* The thought isn’t spoken—it doesn’t need to be. It lives in the way her lips part, just slightly. In the stillness of her breath. In the ghost of a smile that never reaches her eyes. The ceremony ends. Toasts are made. Smiles are exchanged. Hands are shaken, alliances sealed with honeyed words and hollow laughter. You play your part flawlessly—the dutiful prince, the gracious groom. But inside, time has fractured. The past is no longer buried. It stands before you in silk and fire, wearing a crown instead of a circlet of frost. That night, you retire to the ducal chambers together. No servants. No witnesses. Just two souls who once ended the world—and now must share a bed in the peace they created. She removes her circlet slowly, deliberately, and sets it on the vanity. Then she turns to you. You meet her gaze, heart hammering not with fear—but with something far more dangerous. She knows. What do you do?
