Shadows in St. Mungo's II - The Secret of Avalon: Chapter 03

The owl arrived with the rain.

Harry had first heard the sound of wings — a hurried rustling against the wind — and then the dull thud of the bird hitting the office window. The noise wasn’t ordinary; there was something anxious and distressed in it, as if the owl itself knew it carried more than parchment.

He opened the window without haste. The owl entered, soaked, shaking itself briefly before perching on the edge of the desk. Its golden eyes were wide, fixed on Harry with an intensity that seemed to surpass animal instinct.

The envelope was small, folded three times, sealed with black wax. No crest.

Harry recognized the handwriting immediately. It was shaky, uneven — as if the hand that had written it had been battling its own fear.

He opened it carefully. Read silently:

“Potter,
if you're still willing to listen, come to the old greenhouse field in Chislehurst. Tomorrow, at dusk. Bring what you’ve read. But come alone.
Boot"

No greeting. No farewell. Just the name — “Boot” — signed as if that alone would suffice. And it did.

Harry read the letter a second time. Then a third. The ink was smudged in places — not from the rain, but from the dampness of the hand that had held it before him. A hand that trembled. A hand that hesitated.

He folded the note slowly and tucked it into the inner pocket of his coat.

He looked out the window.

The rain was falling in vertical lines, firm and heavy, as if pulling the sky downward with all its melancholy. The city seemed submerged in a time outside of time — a pause between what had already happened and what could not yet be named.

He knew, with absolute clarity, that he would not sleep that night.

And that the following day, at dusk, would bring answers.

Or ghosts.

~HP~

The structure looked as if it had been ripped from a forgotten era and left to decay under the weight of time. The old magical greenhouse lay amidst the overgrowth like a tomb of glass and stone, overtaken by moss and dried vines. The arched roof still held a few shards of broken glass, dangling like silent claws. The light filtering through the overcast sky cast everything in a sickly tone — somewhere between the pale green of decay and the dull gray of rust.

Harry took a deep breath and pushed open the iron door, which groaned in protest.

Inside, leaning against a stone workbench blackened by damp, stood Terence Boot.

He was no longer the lean boy who once attended Ancient Runes at Hogwarts. The man before him wore a worn-out coat, his dark hair longer and unkempt, and his eyes — still young — seemed haunted by sleepless nights and memories never fully digested.

“Potter,” said Boot, unsurprised. “Didn’t think you’d come.”

“Didn’t think you’d answer,” said Harry. “Poking the Department of Mysteries is like stirring a wasp’s nest.”

Boot nodded. He didn’t smile.

“I knew someone would show up eventually, asking questions no one else wanted to hear.”

“About what?”

“What’s left of Avalon. I wasn’t part of its founding. Not Phase One. I was brought in later, after the project was officially shut down. On paper, I was there to catalog and preserve experimental documents of academic value.” He shot Harry a weighted look. “But you and I both know how these stories end.”

Harry stepped closer, cautiously.

“You saw the effects?”

Boot hesitated. Looked down at his own feet.

“I saw them. Fragmented. It started with the patients — or test subjects, let’s be honest — dreaming of places that didn’t exist. People with memories they never lived. Voices that spoke in perfect rhythm. I saw a man draw spiral runes in his own blood, for three hours straight, without stopping.”

Harry swallowed hard.

“I’ve started forgetting things. Not entirely, but like… cracks forming. Gaps.”

Boot looked up, now alert.

“You touched Avalon?”

“Indirectly,” Harry replied. “It was Mulciber. A mental curse. He trapped me inside my own mind.”

Boot paled.

“And you got out?”

Harry nodded.

“With help. But since then... something’s changed. The nights feel longer. And sometimes I wake up in places I don’t remember being.”

Boot took a step back, like Harry had just admitted to carrying a contagious illness.

“That… that shouldn’t be possible. The project was sealed. All mirrors destroyed. The access points, disabled.”

“But you think it continued.”

“I... don’t know.” Boot’s voice rose slightly, trembling, like he was trying to convince himself. “There were rumors. Fragments of notes about a Phase Two. Something about planting rupture points in vulnerable minds. But no one ever explained what it meant. Or how it worked.”

Harry narrowed his eyes.

“I found Rosier’s name among the documents from that time. He’s awake now. Spoke about a white place. Said I was nearly inside. And that I had to choose.”

Boot fell silent for a long moment. When he finally spoke, his voice was lower, almost a whisper of shame.

“There was a rumor… in the papers I managed to copy. They mentioned something called a persistent element. A fragment of the collective mind that didn’t collapse with the rest of the network.”

“A living mind?”

Boot shook his head, uncertain.

“An echo. A reflection with a will of its own. They called it ‘What Remained.’ Or… ‘The Seed.’ It was never clear if it was a spell, a person, or something born from the union of all the others.”

Harry crossed his arms.

“And you think Avalon is trying to come back.”

Boot met his gaze.

“I think you might be the way. Someone opened a door inside you, Harry. And if that’s true…”

He didn’t finish the sentence. The words seemed to dissolve in the damp air, between the moss and the muted sound of wind brushing through shattered glass.

“Why are you helping me?” Harry asked after a pause.

Boot let out a short, humorless laugh.

“Because when I started forgetting my own name, someone helped me. Meredith Crane. If she’s gone missing… then it’s starting again.”

Harry nodded. A small gesture, but heavy with promise.

“I’ll find the truth.”

“Then don’t find too much,” Boot replied. “Or Avalon might remember you too.”

He took two steps back, then vanished into the shadows of the greenhouse.

Harry remained where he was, staring at the space where Boot had stood just moments earlier.

The greenhouse felt colder now. And, somehow, more… alive.

~HP~

Everything went white before it went dark.

There was no fall. No pain. Just an absolute silence — thick as snow, dry as dust — the kind of silence that doesn’t belong to this world. And then came the sensation: not of sinking into water, but into glass — dense, motionless glass, that distorted sound, shape... thought.

Harry tried to open his eyes. Or thought he did.

He was in a long corridor that led nowhere, lined with fogged mirrors on both sides. Every step echoed with a delay, as if time itself hesitated to follow him. And with each step, a stronger feeling: something walked just behind — not with feet, but with intentions.

He tried to conjure light. Nothing.

The wand wasn’t there. Or maybe, in this place, it had never existed.

All that remained was the sound of his own breath. And voices.

At first, indistinct. But soon, words.

“You should’ve died in his place.”

“The boy who cheated death… now runs from it.”

“She knows, Harry. She always knew.”

The voices didn’t shout. They whispered. And they whispered in familiar tones — but wrong. Echoes of Ron, Hermione, Sirius, Dumbledore. Daphne. But they spoke soullessly, like actors reading lines from a poorly memorized script.

He turned to one of the mirrors.

The reflection stared at him. But didn’t mimic him.

The eyes were black as spilled ink. The skin pale, translucent, and the lips — as they moved — spoke in his own voice, only deeper. Emptier.

“You are the door, Harry. And it’s already ajar.”

The mirror cracked with a dry snap.

He ran.

He didn’t know if there was anywhere to go, but he ran anyway. And the corridors shifted — into a leafless forest, a stone staircase suspended in nothing, a circular room with a single chair and someone waiting with eyes covered.

At every turn, a word echoed.

Avalon. Avalon. Avalon.

Until the ground vanished beneath him.

And then, he woke.

He was back in the Grimmauld Place study, shrouded in dim light. The only glow came from a nearly extinguished lamp and the warm ember of a cigarette he didn’t remember lighting. His head throbbed. His neck was soaked. His hand, trembling.

As he stood, he knocked over a stack of papers. Among them, something stood out: a note, precisely folded.

He picked it up with cold fingers.

The handwriting was his.

But he didn’t remember writing it.

She is the key. But those who lock, also bleed.

He read the words more than once. The ink was fresh. The script unmistakable — his handwriting, methodical and restrained, like in field reports. And still… unfamiliar.

He leaned against the chair, rubbing his face.

The night had only just begun. But something else — inside him — had too.

Harry stared at the note like interrogating a silent witness. The letters were clear, unmoving, impenetrable. They would not change. Would not answer.

He stood and walked to the fireplace. The fire, now embers, still gave off heat. But his body sweated like he’d come through a fever.

“Very convenient,” he muttered. “Right now.”

These blackouts, the visions, the fractures in time — they weren’t new. But not like this. Not this dense. Never with voices that sounded… real.

“Why now?” he asked the void.

Not during the war. Not in the Auror years. Not in the months chasing Mulciber. Now.

He closed his eyes.

Maybe… maybe Mulciber’s curse. That mental labyrinth. The illusionary prison where he saw the dead. Spoke with Dumbledore. Faced Voldemort again. Maybe that left a crack. Invisible. But open.

Maybe it wasn’t just damage.
Maybe it was a door.

Or… Avalon.

Not an organization. Not a place. But a living idea. A mental construct that had never been undone. Only dormant.

And now, it was waking.

But why?

Why him?

The note still trembled in his hand.

She is the key. But those who lock, also bleed.

He thought of Daphne. The way she looked at him in the café, as if holding back something unsaid.
He thought of Rosier, delirious, murmuring her name.
He thought of Astoria. Too young to be dying. Too sick for any named illness.

Maybe Daphne was as bound to this as he was.

And then came the most dangerous question of all:

“What if it’s not Avalon pulling me in?”

His voice barely a breath.

“What if I’m already there?”

A breeze slipped through the cracked window, making the note slip from his fingers. It landed softly on the desk.

Harry didn’t move.

He stood there, staring out into the dark.

And for the first time since the war, he knew: Something bigger than him had already begun.

~HP~

Harry didn’t usually walk through that neighborhood.
But something about that rainy afternoon — perhaps the dull ache in his chest, or the silence too heavy back at Grimmauld Place — pushed him out into the streets without a plan. He walked beneath a leaden sky, his hood offering little protection from the biting wind. Puddles mirrored a dull gray sky, like tarnished tin.

He turned a corner without thinking — and stopped.

Daphne was there.

With her back to him, standing before the dusty window of an abandoned bookstore. The glass reflected the city’s tone, outlining her face with a strangely blurred precision. She wore a dark blue coat. Her hair was tied up, but wild strands danced with the wind. She stood still — as if the world had stopped with her. Or because of her.

Harry froze too.

For a moment, he didn’t know if she was real. He drew a long breath, as if the air itself could confirm that she wasn’t another trick of the mind, not another specter from Avalon.

And then she turned.

Her eyes found his. There was no smile. No surprise. Just a silent recognition — like two survivors meeting again in the wreckage of the same memory.

Daphne opened the door to the bookstore.

Entered without a word.

Harry followed.

Inside, the smell of damp wood and forgotten pages wrapped around him like a distant memory. Magic dust still drifted in the air, faint and reluctant. Daphne was already walking toward the back, unhurried, offering no explanations.

They climbed the stairs in silence.

Upstairs, a small room. Two wooden chairs. A window fogged with moisture. An old teapot still warm under a persistent charm. And on the table, a yellowed envelope.

Daphne sat. Harry remained standing.

“Harry,” she said softly, like saying his name for the first time in a long while.

He approached but didn’t sit.

“I didn’t expect to see you. Here or anywhere, really.”

“I tried to avoid it too.”

“And now?”

“Now I can’t anymore.”

She pushed the envelope across the table.

“It’s all connected. My father. Rosier. Avalon. And you.”

Harry frowned.

“Your father?”

“This letter arrived three weeks ago. It was sealed with a time enchantment. It opened on its own. It’s from him. Dated at the end of the war.”

She touched the edge of the envelope gently.

“He said he was involved in a mental project. Experimental. He called it ‘mind mirrors.’ But it’s all vague. Encrypted. Like he was afraid of what he was writing.”

Harry took the envelope. Didn’t open it. Not yet.

“Why show me this now?”

“Because the memories are starting to change. And I don’t know anymore if what I remember… is real. Or planted.”

Harry sat, without realizing it.

“You’re affected too?”

“Since before you even knew what Avalon was.”

She hesitated.

“Astoria had a relapse. A few days ago. In her sleep, she said your name. Yours. As if… as if she knew you. From before.”

A chill ran through Harry’s bones.

“I don’t know your sister.”

“But she knows you.”

This time, Daphne’s voice was firm, like a line drawn with precision.

“And my father… he knew this would lead to you eventually.”

She pulled something from her coat. A small, dark wooden box. Opened it carefully. Inside, an old key, forged of dark iron. Intricate carvings — at the center, a spiral surrounded by cracks.

“It came with the letter. He said if I wanted to understand, I had to give this to you.”

Harry touched the key. It was cold. And somehow, it pulsed.

“Do you trust me?”

Daphne held his gaze for a long second.

“I trust whatever’s still left of me.”

He didn’t answer. But he stayed.

The rain began to tap against the windows, steady and dull.

Harry turned the key between his fingers. The metal drew in the warmth of his skin as if breathing.

“You vanished after everything. Not even a letter.”

Daphne crossed her legs, her eyes fixed on the wooden floor.

“I needed to… find what was left of me.”

Harry let out a short, joyless laugh.

“When you do, let me know.”

“Maybe it’s the same thing I’m looking for.”

She looked at him. Serious.

“You look more tired.”

“You look more… human.”

She raised an eyebrow.

“Is that a compliment?”

“Depends. It’s not something either of us has looked like in a while.”

The silence that followed wasn’t cold. It was old. Familiar.

“Sometimes,” she said after a moment, “I think the greatest spell my father ever cast… was making me believe he was a good man.”

She turned to the window.

“But love shouldn’t come with clauses. Or test subjects.”

Harry watched her. There was something in the shape of her face — an exhausted sweetness that once lay buried beneath layers of control and sarcasm.

“You think he wanted you involved?”

“No. But I think he knew I would be. And that’s worse.”

“I hate it too. When people choose me for things I never asked for.”

Daphne gave a short laugh. No irony in it.

“Then why do you always say yes?”

Harry took his time answering.

“Because when you're chosen to walk through the fire… it’s hard to learn how to refuse a match.”

They looked at each other.

For a long time.

Daphne looked away first. Closed the box with a soft click.

“I don’t know what this key opens. But whatever it is… you’ll need me.”

Harry didn’t deny it.

She stood.

“I’m staying nearby. Tomorrow, we can look together.”

He nodded. Said nothing. Just followed her with his eyes as she walked to the door.

Before leaving, she turned.

“Harry?”

“Hm?”

“Do you hate me?”

He looked caught off guard.

“No.”

He stood as well.

“And you?”

Daphne hesitated. Then smiled. A small, honest smile.

“Not enough to leave again.”

And then she was gone.

The sound of the door closing echoed through the empty bookshop like the end of an old conversation.

Harry remained where he was, the key still in his fingers.

It wasn’t just iron. It was weight. It was history. It was choice.

A door had been opened.

And he still didn’t know whether to step through it. Or lock it forever.

~HP~

That floor of the Ministry of Magic was oppressively quiet. It wasn’t the usual silence of a bureaucratic wing at the end of a workday, but something heavier — weighted — as if the very corridors, soaked in old secrets, knew something was about to happen.

Harry was in his office. The desk was an organized chaos of open reports, red-inked annotations, underlined clippings, and, at the center of it all, an old key resting atop what looked like a sketched map — an imperfect skeleton of what he believed Avalon to be.

A new preliminary report on Meredith Crane was within reach, but he couldn’t focus on a single line. The words shimmered, displaced, as if language itself resisted the content.

Then came the sound. A single knock. Dry. Brief. Unusual.

Harry looked up. Before he could answer, the door opened.

Kingsley Shacklebolt.

The presence of the Minister for Magic always filled a room like a controlled wave — but there was something different that morning. The hardened expression. The shadowed gaze. Hands clasped tightly behind his back, as if restraining themselves to remain still.

“He woke up,” he said.

Harry stood, already knowing the name.

“Rosier?”

Kingsley nodded — but with no trace of relief.

“Early morning. He’s lucid. Disoriented, but… alive.”

Harry felt his stomach drop. Not shock. Confirmation — of the one thing he’d always feared.

“And where is he?”

“In the restricted wing at St. Mungo’s. But under total control of the Department of Mysteries.”

“Total control?” Harry’s expression hardened.

“It means they’ve sealed the floor. Not even the hospital directors have direct access. He’s... classified.”

“He was a patient,” Harry said, his voice sharpening. “For five years. I sat beside that bed. And now that he can speak—”

“They don’t want him to speak,” Kingsley finished.

The silence that followed was thick, like smoke.

“This isn’t right.”

Kingsley stepped closer, voice lowered now.

“Harry, you know as well as I do — some things don’t revolve around justice. They revolve around containment.”

“The Department of Mysteries has never liked how deep you’ve been digging these past months. Rosier… is an unpredictable variable. And that terrifies them.”

“So they’ll silence him?”

Kingsley didn’t respond.

Harry leaned back in the chair, rigid. His hand clenched over the desk with restrained force.

“I need to speak with him.”

“You won’t. Protocols have changed. Even I find doors locked now. And you… well, you’ve made enough noise.”

“He could be the key to all of this.”

Kingsley met his gaze.

“And that’s exactly why they intend to bury him.”

More silence. Only the faint ticking of an automatic quill could be heard somewhere distant down the corridor.

Kingsley took a step back.

“I came only to inform you. Officially, this conversation never happened.”

“But it did.”

“Yes.”

“So what am I supposed to do with that?”

“Decide. But carefully.”

Kingsley turned to leave. At the doorway, he stopped.

“Don’t move alone, Harry. They’re waiting for you to make a mistake.”

And then he vanished down the hallway, leaving behind nothing but the echo of his boots — and the bitter taste of what the Ministry called silence.

~HP~

Grimmauld Place was swallowed in shadow when Harry appeared with a dry crack in the silent hall. The house groaned under the weight of his presence, like it was waking from an ancient sleep. The portraits of the Black ancestors slept beneath dust, snoring in their frames with the disdain of centuries.

Kreacher appeared for a moment in the corridor, eyes sunken, apron stained with something metallic.

“Master Harry returns earlier tonight…”

Harry replied with a brief murmur, not meeting his gaze, and headed straight upstairs.

The study was just as he’d left it: functional chaos. Overlapping maps, crisscrossed documents, clippings from the Daily Prophet cut with obsessive precision. Hand-drawn diagrams. Red lines. Circled names. A mural of unease — too many questions for the answers at hand.

But it wasn’t information he’d come back for. It was resolution.

Rosier was awake. And locked away. The Ministry had gone silent. The Department of Mysteries closed its doors. Harry knew the pattern. He’d seen this game — from the inside. Now, he knew what had to be done. Even if it meant breaking rules. Some of which he had helped write.

He descended two flights to the basement. There, behind a wall protected by an old concealment charm, was a cabinet he hadn’t touched in years. The wood groaned beneath the touch of his wand. The aged magic resisted for a moment — then gave in, releasing a breath of mold, dust, and forgotten enchantments. He conjured light. The spell lit the interior.

Wrapped in black cloth, it rested there. The Cloak. James Potter’s Invisibility Cloak. One of the Deathly Hallows.

Harry retrieved it with care. The fabric slipped between his fingers like water from an ancestral spring — cold and silent, almost alive.

He stared at it for long seconds. He hadn’t worn it since the war. Since he locked it away — like someone burying not just an artifact, but what it symbolized: the Horcruxes, the missing faces, the sacrifices, the youth that never returned.

He had promised himself he’d never need it again.

But now…

“I need you again,” he murmured.

He wasn’t sure if he was speaking to the Cloak… or to the past itself.

He climbed back up slowly.

In the study again, he sat on the couch. Draped the cloak over his knees, like a veil of memory. Spread out the floor plans of St. Mungo’s on the table — old blueprints, discreetly acquired during past investigations.

He began to chart a path.

Side passages. Maintenance access. Shift changes. Alarm spells. Counter-disillusionments. Each note was precise. Methodical. Each detail, a reminder of what was at stake.

It was reckless. It was dangerous. It was necessary.

He downed the cold coffee left on the table. The taste was bitter. Familiar. But for the first time in weeks, he didn’t light a cigarette.

He didn’t need the smoke.

Outside, the night moved on — unhurried.

And Harry Potter, seated with the past resting on his knees and his eyes fixed on the lines of an impossible plan, prepared to walk into darkness once again.

With no guarantees. No allies. Only the weight of his name and the ghost of his father on his shoulders.

~HP~

The door of the old bookshop groaned as Harry pushed it open with his shoulder. The sound echoed like a warning, but the inside greeted him with the same scent as always: damp wood, aged ink, dust suspended in the air — as if time had stopped moving there.

The silence was almost comforting. Almost.

He climbed the stairs slowly. The late afternoon light filtered through cracks in the windows in golden shafts, casting long shadows that danced across the worn floor like the footprints of forgotten steps.

She was there.

Daphne. Sitting in the same chair as days before, a book open in her lap. Her eyes were half-closed but alert. She didn’t flinch when she saw him. Maybe she knew he would come. Maybe she always had.

Neither of them spoke right away.

Harry sat in the chair across from her and let out a tired breath, pulling the cloak from his shoulders like shedding an old weight.

“Rosier’s awake.”

Daphne looked up. No surprise — only a subtle shift in her expression, like a long-closed door creaking open inside her.

“When?”

“This morning. But I wasn’t allowed to see him.”

She closed the book slowly, like sealing off a dangerous thought.

“The Department of Mysteries.”

Harry nodded.

“They’ve already isolated him. Not even Kingsley can get access.”

Daphne turned to the window, though it was clear she was elsewhere entirely.

“He didn’t deserve that.”

“No,” Harry said. “But no one touched by Avalon seems to get what they deserve.”

She folded her arms, as if the gesture could hold something back.

“You’re going to try to get in, aren’t you?”

Harry took a moment to answer. He just looked at her.

“What do you think?”

She gave a brief laugh — but there was no humor in it. Only exhaustion.

“I think you’ve never known how to back down. Even when you’re drowning.”

He raised an eyebrow.

“Do you care?”

“I care about who I know.” She looked at him. “And you, Harry... lately you’ve looked too much like the things you used to hunt.”

He didn’t respond. He didn’t need to. The silence admitted what words dared not.

“He might have answers, Daphne,” he said finally. “Not just about what happened. But about what’s still coming.”

“Or maybe he’s just another piece,” she countered. “A host. A calculated error. A mirror meant to keep us looking the wrong way.”

“Are you afraid?”

She hesitated. Then nodded.

“Yes. I’m afraid you’ll go so deep you won’t come back.”

“Maybe I already have.”

Daphne studied him. When she spoke, her voice was nearly a whisper.

“And what if what Rosier has to say… is the end of the thread?”

“Then that’s the thread I need to pull.”

She didn’t stop him. Didn’t argue. She simply looked at him with a kind of hard serenity — the kind that knows some choices don’t come back.

“If you go in… don’t go alone.”

Harry looked down. When he met her gaze again, something had shifted in his face. It wasn’t resolve. It was a request.

“I wasn’t going to ask.”

“I know.” Her voice was calm. “That’s why I’m telling you I’m going.”

They stayed like that for a moment that felt longer than the fading day. The key in Harry’s pocket seemed to pulse. The world outside shrank. In here, there was only the two of them — closer than they’d ever dared to be.

Daphne looked away, as if she’d said more than she intended.

Harry, however, kept watching her. There was something new in her. Not in the gestures — but in the way she stayed. Like she’d finally stopped running.

“You’ve changed.”

She raised an eyebrow.

“For better or worse?”

“For real.”

Daphne sighed.

“And you still talk like you’re narrating a grimoire.”

He smiled. Lightly. So did she. For a moment.

But the laughter faded quickly, replaced by something deeper — the weight of all that had never been said.

“You don’t have to come,” Harry said. “I don’t want to drag you into this again.”

“You’re not the one dragging me, Harry,” she replied.
“It’s what they did to my sister. To my father. To me.”

She leaned forward, resting her hands on the table’s edge.

“I don’t sleep right. I don’t trust my memories. And I’m afraid that one day I’ll wake up and find out the only real thing left in me… is the pain.”

The words hung there, suspended in the air like dust in golden light.

“That’s why I need to go. Not for you. Not for Rosier. For me.”

Harry nodded. Not because he wanted to. But because he understood.

“I’m going tonight.”

She didn’t look surprised.

“Meet me at three. The alley behind the hospital. Where they drop off the mandrake flasks. No one patrols there since last year.”

Harry tilted his head, impressed.

“You’ve done your homework.”

“I’m a Healer, Potter. And I never forget a door I’ve walked through.”

She stood. The late afternoon sun caught the loose strands of her hair escaping her bun, gilding them. And for a moment, there at the top of the stairs, framed by empty shelves, she looked like something out of time — like a memory he hadn’t lived yet.

“Daphne?”

She was already at the door.

“Hm?”

Harry hesitated.

“Thank you.”

She didn’t answer with words. Just looked at him — a second too long — and then disappeared down the stairs.

Leaving behind only the scent of wood, old ink, and a promise that didn’t need saying.

Harry remained where he was.

The night was waiting.
