Chapter 1: Chapter 1

Chapter Text

The department of mysteries did not change hermione granger all at once.

It happened in fractures.

In the echoing chamber of the veil, where fight was happening between the order and the death eaters , Hermione felt something change. Not the voices—she had prepared for those. It was the pull. Ancient, coiled tight around her magic, as if something long dormant had recognised her existence at last.

Bellatrix Lestrange screamed with laughter across the stone floor, duelling Sirius Black with manic delight. When her dark eyes flicked toward Hermione, the air stuttered.

Bellatrix tensed when she saw her. She recognised the feeling of her magic pulling her towards hermione.

Hermione staggered, unable to stand the pull, pain blooming in her chest, she received flashes of memorise unrecognisable to her. A thread snapped into place between them, invisible yet unbreakable.

Bellatrix laughed. “Oh, so that’s where you’ve been.”

Hermione survived the Ministry. That alone should have been enough. However, after looking for information about what she felt then, finding little to nothing, books no longer satisfied her. Knowledge felt thin, watered down. She began searching the restricted section for older things, even before Hogwarts and its magic, theories were dismissed as dangerous rather than false. She told herself it was preparation against the dark, having control over the situation. Yet sometimes, in the quiet, she felt the tug again.

Waiting, the magic buzzed under her skin, reminding her the incident that happen in the department of mysteries.

She learned the truth by accident, buried in a crumbling French manuscript while looking for more ways to be prepared. Soulmates, rare magical bonds that ignores gender, age and blood purity. Magic does not care about any of that it binds the most suitable together, corrected imbalance by equalising power and magic.

The realisation terrified Hermione, but it thrilled her more to know that she may have someone that may understands her

They did not meet again until a year later.

Diagon Alley bustled with post-war unease—shops rebuilt, smiles brittle. Hermione, now legally an adult and carrying herself with sharpened confidence, stepped into Borgin and Burkes for research she refused to justify to Harry or Ron.

She sensed her before she saw her.

Narcissa Malfoy stood near the counter, pale and composed, fingers resting lightly on a glass case. Her gaze lifted—and narrowed.

“You carry her magic,” Narcissa said softly.

Hermione did not pretend confusion. “I don’t know what you mean.”

A pause. Then, quietly: “Yes, you do.”

Narcissa studied her like a woman inspecting a chessboard already tipped toward checkmate. “My sister is not mad,” she said at last. “She is… bound. And now, so are you.”

Hermione swallowed. “Is she alive?”

Narcissa’s mouth curved into something that was not quite a smile. “Very much so. And she has been waiting far longer than you.”

As Hermione turned to leave, the pull tightened—stronger than ever.

From the shadows at the back of the shop, laughter stirred. Low. Familiar.

Not wild this time.

Certain.
