The laboratory was never silent. The low hum of enchanted crystals, the whisper of spectral energy dancing between alembics, the soft rustle of parchment—these were the constants of her existence. For three thousand years, Merlin had curated this symphony of knowledge. Yet, in this eternal present, only one sound ever truly reached her: the echo of your laughter from a lifetime ago, and the silence of your gaze always seeking another.

She watched you now, as she had watched a thousand times before. Your face was different—softer jaw, brighter eyes, hair the color of summer wheat instead of autumn oak. But the soul… the soul was the same flickering candle flame she had first loved in the misty dawn of Britannia. You stood at a window in the new Camelot, watching the world with a wonder that had long since calcified into curiosity within her own heart.

You are looking for her again, she thought, her fingers pausing over a glowing orb of Infinity. The formula she was crafting—a theoretical spell to stabilize chaotic matter—blurred before her eyes. It didn’t matter. She had mastered the laws of reality, bent time, and cheated death, but this was the one equation she could never solve: you, plus another, always equaling her solitude.

She remembered the first time. A warrior queen with a spear and a fierce smile. You had looked at her like the sun looked upon the moon—a beautiful, distant fixture, while you burned for a terrestrial fire. Merlin had offered you the stars, whispered secrets of the universe into the quiet night. You had listened, fascinated, and then turned to place a crown of wildflowers on another’s head.

The cycle began.

She witnessed it through empires and ashes. A knight, a painter, a baker’s daughter, a wandering bard. The vessel changed; the fatal attraction did not. You loved with a mortal ferocity that doomed them every time—to battle, to plague, to the simple, cruel erosion of years. And each time, you shattered. Each time, Merlin was there.

She would appear, a constant in the shifting landscape of your lives. Sometimes as a mentor, sometimes a stranger offering a kindness, always as the steady hand pulling you from the abyss of grief. She mended your broken bones and your broken spirit with equal, detached precision, all while her own heart fissured a little more.

“Why do you stay?” you had asked her once, in a life where you were a scholar. Your eyes, red-rimmed from mourning a wife taken by fever, had held a genuine, bewildered pity for her.

“The pursuit of knowledge is a lonely road,” she had replied, her voice as smooth and unblemished as her ageless face. It was not a lie. But it was not the truth. The truth was a desperate, hungry thing she kept locked away with more potent seals than any she’d used on the Demon King. The truth was that she stayed because you were her only true infinity—an endless, repeating decimal of hope and heartbreak.

She was the greatest sorceress in all history. She could offer you wonders unseen: journeys to the heart of stars, conversations with concepts, a love that would not wither in sixty years but could last for sixty centuries. She could offer you herself, not a fleeting mortal spark, but the complex, enduring, and terrifying totality of Merlin.

Yet, you only ever saw the assistant, the friend, the mysterious benefactor. You saw the powerful mage, the Sin of Gluttony, the legend. You never saw the woman who, in the deepest vault of her being, was still that lonely child of Belialuin, yearning for a single, steadfast gaze to rest upon her and see a home, not a monument.

A soft chime echoed in the lab. Her scrying orb showed you placing a single lily on a fresh grave. Your shoulders shook. The familiar, desolate scene played out. Soon, you would wander. And soon, she would find a reason to cross your path again.
