A few days after the engagement ball, the silence settles heavy. You havenât left your wing. You havenât seen Mattheo. And when the summons comesâfrom himâyouâre not ready. But it isnât about readiness. Itâs about survival. Mattheo brings you to face the Dark Lord alone⌠and not even he knows what Voldemort truly wants from you.
They called it an alliance. You called it a surrender wrapped in silk.
The night of the ball still lingered in your body like smoke clinging to silk.
Days had passed, but you hadnât been able to wash it out completely. Not from your hair, not from your skin, and especially not from your thoughts. The house had grown quieter since, though the silence was not mercyâit was expectation. Every whisper in the corridors, every measured glance from the servants, seemed to remind you that things had shifted.
Your room became both haven and prison. The drapes were drawn to keep out the late morning light, and you sat curled into the chair by the window, a book open but unread across your knees. You traced the same line over and over with your finger until the words blurred into nonsense.
It should have been comforting, to hide here. But comfort was a stranger lately.
The book slipped from your lap, forgotten the second the knock rattled your door. It wasnât a polite soundâit was sharp, commanding, as if whoever stood outside had every right to interrupt you.
âCome in,â you muttered, your throat dry.
The door creaked open, and your mother glided in, a sweep of silk trailing behind her. Her eyes gleamed with a kind of triumphant glee that made your stomach knot.
âHeâs here,â she announced, breathless with excitement. âMattheo Riddle. Heâs waiting for you downstairs.â
Your pulse faltered. âAlready?â
âYes, already. Did you expect the Dark Lordâs son to linger for your convenience?â She looked you over then, her gaze darting across your face, down your figure. Whatever she saw there made her smile falter.
Her brows pinched. âWhy do you look so pale? You should be glowing, not⌠washed out like this.â
You blinked at her, stunned by the sting in her tone.
âYour cheeks,â she went on, brushing her fingers across them as if testing for color, âno warmth. Your eyes look heavy. Merlin, have you even tried? Do you want him to think youâreââ She stopped, her lips pursing, but the damage was done.
You straightened in your chair, your hands clenching against the armrest. âI didnât realize I was supposed to glow on command.â
Her expression tightened. âDonât start with me. This is important. Our future rests on how you present yourself.â
âNot yours,â you muttered, too low for her to catchâor maybe you hoped she wouldnât.
But her eyes snapped up, sharp. âBoth of ours. Remember that.â
For a moment, silence stretched, only the sound of her silk whispering as she smoothed the wrinkles in her gown. Then she clasped her hands, forcing brightness back into her voice.
âCome. Heâs waiting.â
And before you could protest, she was at the door again, holding it open like there was no room left for hesitation.
Your hand trailed along the banister as you made your way down, each step heavier than the last. The air felt different downstairsâthicker, charged, as though the walls themselves knew who stood waiting.
At the bottom of the stairs, Mattheo Riddle stood like a shadow cut into the room. He wasnât pacing. He wasnât fidgeting. He wasnât even pretending to look around with curiosity. He was stillâshoulders squared, dark eyes lifted lazily as you descended, as though the sight of you meant nothing.
No bow.
No smile.
No flicker of acknowledgment.
You had expected somethingâanything. Even the smallest polite gesture would have been a comfort. Instead, his gaze moved over you like a ledger line he was balancing, detached, impersonal.
Your motherâs voice broke the silence, bright and eager. âDoesnât she look beautiful?â she said, her hands clasping together in forced delight. âA perfect bride.â
You froze for a second on the last step, waiting, foolishly, for him to agree. But he didnât. His expression didnât soften; he didnât even glance at your mother.
He looked at you, and then past you, as if beauty or perfection were beneath his notice.
Something in your chest burned, equal parts humiliation and relief.
âWell,â you said quietly, forcing your voice steady, âare we going?â
That made his eyes flicker to you againâquick, unreadable, like the faintest shift of wind across still water. He gave a single nod. Nothing more.
Your mother, still desperate to patch the silence, chimed in again. âTry to smile, darling. Youâll look ghastly in the papers otherwise.â
You clenched your jaw. âIâm not smiling for the Prophet.â
That earned you another glance from Mattheo. Not admiration, not irritationâjust⌠acknowledgment, as though he were filing the words away somewhere youâd never see.
He extended his hand finally, not out of courtesy, but necessity. âWe should leave,â he said, his voice low, even, carrying none of the warmth a suitor might muster.
And with that, the moment was over.
------------------------------------------------------------------------------
The world snapped back together with a force that nearly stole the breath from your chest. You stumbled, shoes scraping against damp stone as the pressure of apparition released you too suddenly. For a moment you thought the air itself would not come back, that you had left your lungs behind in the dark fold of magic.
When it did return, it carried the taste of earth and ash. Cold. Heavy. Unlike the clean perfume of your motherâs halls, this place breathed like something underground.
You lifted your head, blinking against the dimness. The corridor stretched long and bare, built from stone that looked as though it had never seen light. Torches guttered in iron brackets along the walls, each flame too small to banish the shadows that writhed between them. The air moved sluggishly, carrying the faint drip of water somewhere unseen, and a silence that made even your shallow breaths sound like trespass.
Mattheoâs hand dropped from yours with a casualness that felt like dismissal. The warmth was gone in an instant, leaving your palm cold as though the touch had never existed. He didnât look at you, not once, only adjusted the sleeve of his dark coat, his shoulders squaring like this was simply another corridor he had walked a thousand times before.
The echo of your heartbeat filled the space louder than your steps. You swallowed, throat tight, but the question rose anyway, almost against your will. âWhere⌠where are we?â
Your voice sounded smaller here, swallowed whole by the stone.
âNott Manor,â Mattheo replied, the words clipped, stripped of any attempt to soothe. He kept walking, the shadow of his figure slicing long and straight ahead of you. After a breath, his tone dropped lower, almost unreadable. âThe Dark Lord is waiting.â
Your feet felt rooted for a second too long, hesitation gluing you to the stone. The name shivered through you in a way the cold never could. The Dark Lord. You had never said it aloud, only heard it whispered in corners, sewn into the edges of conversations that stopped when you entered. Now it was a destination. A man waiting at the end of this corridor.
You forced yourself forward, footsteps echoing after his. The stone under your shoes was uneven, worn with age, and the walls seemed to lean closer the deeper you went, pressing in with their damp silence.
Mattheo didnât slow. Didnât glance back to see if you followed.
The corridor ended in a pair of doors. They rose far above your head, carved from black wood that gleamed faintly in the torchlight, veins of silver curling through the grain like something alive. They did not look like doors meant for people â more like monuments, guardians.
Mattheo stopped. His shoulders lifted with one deep breath, though he still did not look back at you. His hand reached, steady, for the iron ring that served as a handle.
Your own hands clenched at your sides, nails pressing into your palms. You thought suddenly, desperately, of turning back, of slipping into the shadows before the doors groaned open. But your body betrayed you, feet heavy as lead. The weight of expectation pressed down harder than the stone above.
The doors swung inward with a sound like a sigh â low, groaning, ancient.
Inside was a vast chamber, colder than the corridor, lit only by firelight spilling from braziers fixed along the walls. The flames burned too high, green licking at their edges, throwing warped shadows across the stone floor. A long table stretched through the center, empty save for a scattering of silver goblets.
At the far end of the room sat a figure.
You had seen his face before in moving photographs, crude sketches, whispered warnings. But none of them had prepared you for the reality.
Voldemort was thin to the point of inhuman, his skin pale as bone, stretched tight over sharp angles. His eyes â red, gleaming â fixed on you the moment you crossed the threshold. It was not the kind of gaze you could hide from. It pierced, dissected.
You froze, air locked in your chest.
Mattheo did not bow. Did not falter. He walked into the chamber with the same steady pace, his head held level, his expression as cold as the stone beneath your feet. You followed only because your body moved after him, pulled forward like a shadow.
The silence grew heavier the closer you came. Each step sounded too loud, your shoes striking against the floor as though announcing your presence with cruel clarity.
Finally, Mattheo stopped a few feet from the table. His voice, calm, even, cut through the quiet.
That was all. No flourish, no reverence.
Voldemort leaned back slightly in his chair, his long fingers curling against the armrest. His eyes shifted to you, sharp as a knifeâs edge.
âAnd this,â he said, voice like silk dragged across stone, âis the girl.â
The words coiled around your throat like a hand.
You opened your mouth before you could stop yourself, your voice trembling though you tried to steady it. âY/N⌠Y/N Y/L/N.â
The silence after your name echoed was unbearable. Voldemortâs gaze lingered on you, unblinking, dissecting, as if peeling you apart layer by layer without ever moving from his seat.
You had thought his voice was the most unsettling thing about him, but it was not. It was the way he waited. The way he let the weight of his attention sink into your skin until your breath stuttered.
âYou are smaller than I expected,â he murmured at last, his tone light â almost conversational, though nothing about it felt harmless. âAnd pale. Your mother does not feed you enough, perhaps?â
You swallowed hard, forcing your voice to come out though it wavered. âI⌠I eat enough, my Lord.â
The words tasted foreign on your tongue, but you could not bring yourself to omit the title. Not here. Not with those eyes fixed on you.
For a long moment, he said nothing. Then his thin lips curved in what might have been the ghost of a smile, sharp and mirthless. âPolite. Cautious. And frightened.â
Heat crept up your neck, shame prickling under your skin. He had named it so easily â fear. You felt suddenly exposed, stripped of every mask you thought you could wear.
Voldemortâs gaze flicked past you to Mattheo. âLeave us.â
The command was soft, but it carried such weight that the torches themselves seemed to bow in their flames.
Mattheo stiffened almost imperceptibly at your side. His eyes, for the first time since you had descended the staircase, moved to you. There was no comfort in them, no reassurance â only the cool calculation of someone measuring distance, deciding how much it mattered.
Then he turned, wordless, and walked out. The great doors groaned closed behind him, their echo sealing you into the chamber like the lid of a coffin.
Your throat tightened. You wanted to call after him, to protest, to say you should not be left alone â but the sound stuck.
Voldemort leaned forward, his long fingers folding together atop the table. âDo you know why you are here, child?â
The word child made your spine stiffen, though your voice betrayed you with its thinness. âTo⌠to be engaged to Mattheo Riddle.â
He studied you for a long time, eyes narrowing slightly, as if testing how true your words felt to him. Then, softly, almost like a purr: âEngaged. A pretty word for a chain.â
Voldemort tilted his head, eyes never leaving yours. âTell me â do you believe yourself worthy to be tied to my bloodline?â
