The stones of Hogwarts still smelled of ozone and grief. Elara Vance ran a gloved finger over a scorched patch of wall near the Great Hall, the granite rough and flaking under the fine dragon-hide. Six months. Six months since the battle, and the castle still bore its wounds like an old soldier. She understood the sentiment.
Before pushing open the heavy oak doors, she stopped. Her fingers, still resting on the frame, tapped. *One. Two. Three.* A quick, precise rhythm, a nervous habit she’d never managed to break. It didn’t *do* anything, she knew that. But not doing it felt like walking under a ladder while breaking a mirror. Unwise.
Hermione Granger was waiting just inside, looking thinner than in the *Prophet* photographs. The war had sharpened her, carving away the last of her schoolgirl softness and leaving something keen and severe in its place. There were no pleasantries.
“Vance. Thank you for coming on such short notice.” Her voice was flat, efficient. She gestured for Elara to follow. “The damage is… extensive. We’re cataloguing everything recovered from the detritus. Your expertise is in runic decay patterns, correct? Specifically with silver enchantments.”
“Among other things,” Elara said, her own voice quiet. She fell into step beside Granger, her boots making soft sounds on the flagstones. They passed tapestries of ridiculously valiant-looking Gryffindors battling creatures that had clearly been embellished by the weaver. Honestly, the lack of subtlety in this part of the castle was an affront to good taste. Give her the cool blues and bronze of Ravenclaw Tower any day. At least there, one could think without being assaulted by primary colours.
“We have a particular artifact that has resisted preliminary diagnostics,” Hermione continued, her pace brisk. She didn’t seem to notice Elara’s brief flicker of disdain for the decor. “Standard revealing charms dissipate before contact. Even Professor Flitwick was unable to get a reading.”
That got Elara’s attention. Filius Flitwick forgetting more about Charms than most wizards ever learned. If he couldn’t scan it, the object wasn’t just damaged; it was actively hostile to inquiry. “Where was it found?”
“The base of the Astronomy Tower.”
They descended into the dungeons. The air grew colder, cleaner, scented with damp stone and something vaguely herbal. It was a relief. Here, the magic felt old and settled, not scarred and raw like the upper floors. Hermione stopped before a nondescript storeroom door, identical to a dozen others they’d passed.
“He’s waiting inside,” Hermione said, a slight, unreadable tension entering her voice. She didn’t elaborate on who ‘he’ was. She simply pushed the door open into a small, cold chamber lit by a single, shivering globe of cold light.
And there he was.
Severus Snape stood with his back to them, examining a row of carefully labelled jars on a high shelf. He was not dead. The shock of it was a physical blow, knocking the air from Elara’s lungs. The papers had been so certain. Nagini. The Shrieking Shack. A hero’s, or at least a martyr’s, end. Yet here he was, clad in his customary black, looking no more spectral than usual.
He turned, his eyes sweeping over Elara in a familiar, dismissive appraisal. “Vance. You were recommended.” His voice was the same low drawl, dripping with the same lack of enthusiasm she remembered from her N.E.W.T. Defence classes.
“Professor,” she managed, her throat suddenly dry.
“I am a professor no longer,” he bit out. “Granger, you may leave us. Your… optimism is not required for this.”
Hermione gave a tight, frustrated nod, shot Elara a look that was impossible to decipher, and departed, pulling the heavy door shut behind her. The click of the latch was deafeningly loud in the sudden silence.
Snape gestured with his chin toward a small, velvet-lined crate on a central table. “The artifact is there. Do not touch it directly. Report your findings. Do not speculate.”
Elara took a breath, pushing aside the thousand questions threatening to spill out—about his survival, his presence here, his role in this new, recovering world. She was a professional. She had a job to do. That was all that mattered. Tapping her temple three times with her index finger, a barely conscious motion, she approached the table.
Inside the crate lay a silver music box. It was small enough to fit in her two hands, its surface intricately etched with floral patterns and a winding border of what looked like Elder Futhark runes. It was dented on one corner, the lid slightly ajar, and a dark, spidery network of cracks radiated from the point of impact. It looked like a child’s toy. Sentimental tat, most likely, dropped in the chaos of battle.
“It has a name?” she asked, pulling on a fresh pair of gloves and retrieving a delicate set of silver probes from her satchel.
“It does not.”
Of course not. Elara set up her workspace with practiced efficiency, laying out probes, lenses, and a small, folded cloth. First, the basics. She would try her own diagnostic, a custom variant designed not just to reveal, but to map the flow of residual magic. It was a gentle, inquisitive charm, less a battering ram and more a curious whisper.
“*Speculum Vestigium*,” she murmured, tracing a complex pattern in the air with her wand. A thin, sapphire-blue thread of light spun from its tip, hovering for a moment before drifting lazily toward the music box.
Then it happened. Or rather, didn't happen.
About a foot from the silver surface, the blue thread of magic just… stopped. It didn’t fizzle out, it didn’t shatter, it didn’t reflect. It was consumed. One moment it was there, a vibrant line of inquiry, and the next it was gone, leaving not even a spark.
Elara stared. That was not possible. Magic could be blocked, redirected, or overwhelmed. It could not simply be annihilated. It had to go somewhere.
“As Granger stated,” Snape’s voice was dry from the corner of the room. “It resists.”
“It doesn’t resist, Professor,” Elara said, her eyes narrowed in concentration. “It… eats.”
This was no longer a simple repair job. This was an investigation. An instinct, honed over years of dealing with cursed and malicious objects, told her to stop. To pack her things, report her findings, and leave. But another, deeper part of her—the part that had sorted her into Ravenclaw, the part that couldn't leave a puzzle unsolved—rebelled. She had been hired to do a job.
She took a different approach. On her own initiative, she put her wand aside. If magic wouldn’t talk, perhaps metal would. She selected her finest probe, a silver needle no thicker than a strand of hair, designed to test material integrity without disturbing enchantments.
“What are you doing?” Snape’s voice was sharp.
“A physical test. If the magical structure is actively hostile, I need to know if the physical structure is stable.” She didn’t wait for permission. Leaning closer, she brought the tip of the probe to the edge of a single, deeply carved rune near the box’s hinge. A Sowilo rune. Sun, or power.
The instant the silver probe touched the silver rune, the world went wrong.
The air in the room plunged, a sudden, bone-aching cold that had nothing to do with the dungeons. The floral etchings and the runes on the box flared with a nauseating, corpse-green light. It wasn’t a glow that illuminated; it was a glow that devoured. The light from her wand, still lying on the table, seemed to bend inward, sucked toward the box. The shadows in the room didn’t retreat from the green light, they deepened, growing thick and heavy.
And the sound. There was no music. There was only a low, discordant hum that vibrated not in her ears, but in the bones of her skull. It was the sound of a string stretched too tight, a moment from snapping.
A presence bloomed in the room, vast and ancient and utterly without pity. It wasn't in the box. The box was merely a keyhole, a crack in the wall through which something monstrous was peering. Elara snatched her hand back as if burned. The silver probe fell from her numb fingers, clattering onto the stone floor.
The green light vanished. The cold receded. The hum stopped.
There was only the box, sitting silently on its velvet bed. It looked exactly as it had before. Dentures. Cracked. Inert. But the air was different now, the silence charged and watchful. She hadn’t fixed a broken thing. She had knocked on a door she should never have known existed.
