    The bells of the Grand Ducal Palace tolled low and solemn, their echoes drifting across marble halls and quiet courtyards as though the past itself refused to fade.

    You were born into legacy—the firstborn of the Grand Duke, heir to a lineage older than empires themselves. Your mother, a princess from a distant, powerful realm, had come not for love but for duty. Their marriage had been one of balance, not affection—respect, not warmth. And yet, to you, she had been everything.

    When she died, you were seven.

    The world did not end in fire or war. It ended quietly—like a candle extinguished in a sealed room.

    Two years later, your father remarried.

    She was nothing like your mother. A common-born woman, soft-spoken, kind-eyed, gentle in a way that felt… wrong within stone walls built on power and bloodlines. You hated her without knowing her. You hated the way your father looked at her—like something in him had finally found peace.

    And when she gave birth to a son—small, fragile, too weak to cry properly—you hated him most of all.

    He was nine years younger than you. Sickly. Pale. Always trembling slightly, as though the world itself weighed too much on his bones. And yet…

    He smiled at you.

    Always.

    With quiet admiration. With innocent warmth. As if you were not the cold figure who never once returned his gaze, but something noble. Something worthy.

    You never saw him as your brother.

    Only as a threat.

    Because whispers grew in the court like rot beneath silk.

    "The new duchess will give the duke a true heir." "The firstborn is too distant… too unstable." "Blood alone does not secure a throne."

    So you trained harder. Studied longer. Fought sharper. Every achievement was not pride—it was survival.

    And then, you turned twenty.

    The ritual was ancient. Binding. Absolute.

    The heir’s guardian would awaken.

    You stood beneath the vaulted dome of the summoning hall, nobles watching with thin smiles and sharpened expectations. Some hoped for glory. Others, failure.

    The air trembled.

    Light fractured.

    Mana surged.

    And then—

    Silence.

    Before you stood… not a towering beast, not a celestial warrior, not a divine entity worthy of your station.

    A child.

    No older than six in appearance.

    Small. Quiet. Barefoot.

    With soft features and wide, uncertain eyes that looked up at you like you were the only thing anchoring him to the world.

    A guardian.

    This?

    The hall did not erupt—but it didn’t need to. You felt it.

    Disappointment.

    Mockery.

    Doubt.

    Your jaw tightened. Your pride cracked—not loudly, but deeply.

    A humiliation.

    You turned away from him.

    And for days, you ignored him.

    He followed anyway.

    Soft steps. Hesitant presence. Never speaking unless spoken to—which you never did. He stayed near, like a shadow that refused to detach.

    Until one night—

    It happened.

    A noble—one of those who smiled too easily in court—cornered you in a secluded corridor, words laced with insult because directly wasn't an option

    But behind you—

    Something broke.

    Mana surged violently, flooding the corridor like a storm unleashed. The air distorted. Walls cracked. Light bent unnaturally.

    You turned sharply.

    The small guardian stood trembling, eyes glowing—no longer soft, but burning with something ancient, something vast and uncontrollable. The sheer force radiating from him made you even take a step back.

    He was afraid.

    Not angry—afraid.

    Because he thought you were in danger.

    “Stop.”

    Your voice cut through the chaos.

    He didn’t.

    The mana spiked higher.

    “Stop!” you snapped again, stepping forward, grabbing his shoulders despite the pressure threatening to crush you.

    His gaze flickered—wild, lost.

    Something human.

    Something he seemed to understand.

    The storm collapsed.

    Silence fell.

    The noble fled without dignity.

    And in your arms, the small guardian trembled—not powerful, not divine—just a child again.
