Hogwarts always had moods.
Harry remembered that from before — the way staircases liked or disliked you, how the portraits whispered more at night, how the castle seemed to breathe with the weather.
But this time, the castle didn't just shift around him.
It watched him.
And it felt alive.
⸻
It started small — a hum underfoot during breakfast one morning.
Harry brushed it off as nerves.
But by lunchtime, as he walked past the Great Hall's tall windows, he felt it again — a faint vibration in the stone beneath his palm, like the pulse of something sleeping too long.
He stopped, fingers pressed to the wall.
A few students gave him odd looks. Ron called, "You alright, mate?"
"Yeah," Harry said absently, but he didn't move his hand.
The wall was warm.
A deep, low warmth, like the echo of sunlight caught in rock.
For an instant, a whisper brushed the edge of his mind — not words exactly, but tone.
Curious. Awake.
Then it was gone.
He exhaled slowly. "Okay. That's new."
⸻
A few days later, Harry and Hermione were in the library, halfway buried under Charms homework.
Hermione was muttering, "It's Wingardium Leviosa, not Leviosar," when Harry's quill began to shake.
He frowned. "Did you feel that?"
"Feel what?"
"The table."
Before she could answer, the quill lifted — not much, just an inch — and began to hover.
No wand. No charm. Just raw will.
Harry froze.
Hermione's jaw dropped. "Harry—"
"I didn't mean to!"
"Put it down!"
"I'm trying!"
The quill spun, wobbling in midair, then shot upward and smacked the ceiling with a faint plock.
It stayed there, trembling.
Hermione's whisper turned shrill. "Harry!"
He clenched his fists, focused on the rhythm — heartbeat, breath, let go—
The quill fell neatly into his hand.
Silence.
Then, faintly, Hermione said, "You're a menace."
Harry grinned, sheepish and exhilarated. "A menace with range, though."
Hermione's glare softened into reluctant amusement. "You're lucky Madam Pince didn't see that."
"Yeah," he said, twirling the quill between his fingers. "Feels like the castle did."
⸻
That night, the castle answered.
Harry had gone for a late walk — something about the air felt heavy, humming again with that same strange rhythm.
He found himself in a corridor he didn't recognize, the stones older and darker than the rest of the castle.
His steps echoed faintly, and with each echo came a note, faint but distinct, like soft music in the walls.
He turned a corner — and stopped.
There, where there had been blank wall a moment ago, stood a door.
Not ornate. Plain oak, silver handle, no markings.
He hesitated.
He should go back.
But curiosity — that old, dangerous instinct — tugged stronger.
He pushed it open.
The smell of dust and candlewax greeted him.
Inside was a circular room lined with carved stone — runes swirling like vines along the walls, a faint shimmer of gold light tracing their edges.
And in the center, an empty pedestal.
Harry stepped closer.
The carvings glowed softly as he approached, reacting to his presence.
He could feel them hum under his skin.
He whispered, "What are you?"
The light brightened.
A wordless sound — something between breath and thought — filled the air.
And then, just for a heartbeat, he saw them: four faint silhouettes, made of magic, flickering like ghosts in a dream.
A man with wild hair and a knowing smile.
A woman crowned in light.
A tall figure in armor.
And one with a serpent coiled around his arm.
The Founders.
The image vanished as quickly as it came.
The runes went dark.
The door behind him shuddered — as if gently urging him out.
Harry stepped backward, heart pounding.
When he looked again, the room was gone.
Just a solid wall of stone.
⸻
The next day, Dumbledore stopped him after breakfast.
"Harry," he said quietly, "walk with me."
They strolled along a high balcony overlooking the courtyard.
The morning light spilled gold through the arches, and for a while, Dumbledore said nothing.
Finally, he asked, "You've felt it, haven't you?"
Harry hesitated. "The castle? Yeah. It's… awake."
Dumbledore's eyes twinkled, but his tone was grave.
"Hogwarts is very old. It remembers every student who has ever lived within its walls. But some it remembers more strongly than others. You, my boy, seem to have stirred it deeply."
"I didn't mean to," Harry said, uneasy.
"Oh, I think you did," Dumbledore replied gently. "Not intentionally, perhaps. But you are… attuned to it. Your magic resonates with the castle's own rhythm."
Harry frowned. "It showed me something. The Founders, maybe. Just… shadows."
Dumbledore stopped walking.
The light caught his spectacles, turning them gold.
"I would be careful where curiosity leads you, Harry. Hogwarts rewards bravery — but it does not always protect the brave from what they awaken."
Harry nodded slowly.
But inside, that same thrill — curiosity, hunger, wonder — refused to quiet down.
⸻
That night, Harry couldn't sleep.
He went to the window and looked out across the castle grounds — the lake glimmering silver, the towers breathing faint light.
Somewhere deep inside those walls, he knew, something was awake — something old, powerful, and curious about him.
He reached out a hand, palm pressed to the cool stone beside his bed.
For a moment, he thought he felt a heartbeat — not his, but the castle's.
He whispered, "I don't want to break you. I just want to understand you."
The wall warmed faintly beneath his hand, as if in acknowledgment.
Harry smiled — nervous, small, but real.
He had no idea what he'd just started.
But Hogwarts, it seemed, was listening.
And so was something else — something far older, waiting in the dark beneath its stones.
