December came to Hogwarts in layers of gold and silver.
Frost glazed the windows of the Great Hall each morning, so that sunlight spilled through like pale fire. The smell of pine and cinnamon floated in every corridor, and enchanted snow drifted lazily from the ceiling of the main hall, vanishing just before it touched the tables.
The castle had always been magical, but at Christmas, it felt alive.
Hermione's revision schedules decorated the tables long after she had gone — precise, color-coded charts for "efficient holiday review." She'd left for home three days before the feast, worrying aloud about the lack of magical libraries in Oxfordshire and pressing an extra quill into Harry's hand "in case Ron eats yours again."
Ron had replied through a mouthful of toast, "Oi, that was one time."
Without Hermione, the Gryffindor common room grew louder, messier, and undeniably happier.
Fred and George strung garlands of self-lighting holly over the fireplace. Seamus set his quill on fire twice while trying to write Christmas cards. Neville accidentally enchanted his own slippers to shuffle around the dormitory by themselves.
Harry found himself in the middle of it all — watching, laughing, and realizing that this was what holidays were supposed to feel like. Warmth. Laughter. Belonging. The opposite of the cupboard.
He helped Hagrid haul Christmas trees into the Great Hall, his breath misting in the cold air. Each tree was three times his height and smelled of fresh resin and forest mornings.
Hagrid's booming voice echoed through the hall. "Lovely, aren't they? Don' think I've ever seen the place look finer. Dumbledore'll be chuffed."
Harry smiled. "It's beautiful."

By the time the last students left for the holidays, Hogwarts had grown quiet.
Harry and Ron were among the few who stayed. The castle without noise was strange — the kind of peaceful that came from being old and self-contained.
That night, Harry and Ron fell asleep in front of the fire after a snowball fight in the courtyard. The flames cast soft, flickering shapes on the walls, and the tower smelled faintly of pine needles and toffee.
When Harry woke the next morning, the fire had burned low, and the common room was filled with early light — and presents.
The Christmas tree in the corner sparkled with gold baubles, and at its base, piles of gifts waited like colorful secrets. Ron was already tearing into one, laughing at a pair of violently orange sweaters from his mother.
"Look, Harry! Mum's at it again — 'R' for Ron, and I bet yours has an 'H.'"
Harry grinned, pulling open his own box to find exactly that: a hand-knitted green jumper with a large gold "H" on the front and a bag of fudge that smelled suspiciously of treacle.
"Best jumpers in Britain," Ron said proudly. "Mum makes them every year."
Harry smiled and tried to speak, but his throat was tight. No one had ever made him a Christmas present before in this life.
Under the tree, though, something else caught his eye — a small, plain package, almost shy among the bright ribbons. There was no tag, only a folded piece of parchment resting on top.
He picked it up and unfolded the note.
Your father left this in my possession some time ago.
It is time it was returned to you. Use it well.
— A Friend.
His fingers trembled slightly as he unwrapped the package.
A silvery fabric spilled out — soft, flowing, almost liquid in its texture. The light caught on it like water over moonstone. When he lifted it, the world behind it seemed to vanish.
The Invisibility Cloak.
Harry's breath hitched. He remembered this — the weight, the shimmer, the way it caught the air. A thousand memories pressed at the edge of his mind, though they weren't really memories from this life. They were echoes — a boy sneaking through corridors, a dragon in a tower, a kiss of moonlight on stone floors.
He ran his hand through the fabric, and for a moment, the world felt still.
Ron peered over his shoulder. "Blimey. That's brilliant, that is. Who'd give you something like that?"
Harry folded the cloak carefully. "Someone who knew my dad."

Christmas dinner that night was everything the Dursleys' holidays hadn't been: warm, loud, and full of laughter.
The Great Hall glowed with enchanted candles; golden plates refilled themselves before you even thought about seconds; and Dumbledore wore a hat shaped like a stuffed dragon that actually breathed smoke.
"Best hat yet," Ron whispered. "Do you think he practices?"
Harry laughed. For once, he didn't care about mysteries or destiny. He was just a boy surrounded by laughter, good food, and light.
When the feast ended, and the others drifted off to bed, Harry lingered, staring up at the enchanted ceiling. Snowflakes fell in perfect silence, disappearing inches above his head. The castle seemed to hum softly around him — old, protective, eternal.

That night, when the world was asleep, Harry lay awake with the cloak folded beside him.
The note burned faintly in his pocket. Use it well.
He hesitated — only for a heartbeat — then stood, draped the cloak around his shoulders, and disappeared.
The sensation was familiar and strange all at once: a cool tingle across his skin, as though he were walking through moonlight that obeyed his thoughts. He moved silently through the corridors, the castle's torches flickering to life in his wake, guiding him like friendly stars.
He didn't know where he was going until he reached the disused classroom — the one with the tall, dust-covered mirror against the far wall.
The Mirror of Erised.
He stepped closer, his heartbeat filling the quiet. His reflection looked back — small, messy-haired, wrapped in moonlight. And then it changed.
Behind him appeared two figures: a woman with red hair that shimmered like fire, and a man with untidy black hair and glasses. Their eyes were warm, their smiles soft and alive. His parents.
Harry's breath caught. He reached out — the glass was cool under his fingers. "Mum," he whispered. "Dad."
They smiled, and his father raised a hand in greeting. His mother's expression was tender and proud and heartbreakingly alive.
Tears blurred his vision. He hadn't realized how much he needed to see them — not photographs, not ghosts, but them.
He didn't know how long he stood there.
When the tears finally slowed, he noticed something else. Behind his parents, further in the reflection, were other faces — older, war-worn, but familiar. He saw Sirius, grinning. Remus, solemn and kind. The members of the Order. And further still… himself. Older. Standing beside them as an equal.
The vision wavered. His parents stepped closer, smiling, and for a terrible moment, he thought he could walk through the glass and join them.
"Beautiful, isn't it?"
The voice came softly behind him.
Harry spun around. Dumbledore stood at the door, hands clasped loosely, his eyes glimmering like melted stars.
"I—I didn't hear you," Harry said, his voice rough.
"I have had some practice at moving quietly," Dumbledore replied with a small smile. He stepped forward, studying the mirror. "The Mirror of Erised," he said gently. "It shows us nothing more or less than the deepest, most desperate desire of our hearts."
Harry swallowed. "I can see my parents. And… other things. It's like it knows everything I've ever wanted."
Dumbledore nodded slowly. "The happiest man in the world would look into this mirror and see only himself, exactly as he is. But very few of us are that content."
Harry stared at the glass. "It feels… dangerous."
"Ah," Dumbledore said softly, "you are wiser than most. Yes, it is dangerous. Dreams have a way of comforting us when we should act instead. Many have wasted away before this mirror, unable to leave its illusion."
Harry hesitated. "Professor… have you ever looked into it?"
The old man's eyes flickered — not away, but through the glass, to something Harry couldn't see. "Yes," he said quietly. "I have. And I saw what I once believed I wanted. What I had lost. But life, Mr. Potter, has a way of teaching us that longing is not the same as living."
They stood in silence. The mirror reflected them both now: a boy of eleven and an old wizard with half a century of choices behind him.
Harry whispered, "Sometimes I think about changing things. Making everything right."
Dumbledore smiled faintly. "And sometimes, that is precisely what must be done. But remember this, Harry — even the greatest wizards cannot see all consequences. To change the world, you must first understand it. And to understand it, you must live in it."
Harry's eyes burned. "But what if it's already too late to fix it?"
Dumbledore placed a gentle hand on his shoulder. "Then you start again — as you have."
Harry looked up sharply. Dumbledore's eyes twinkled with knowing amusement, but he said nothing more.
The Headmaster turned to leave, pausing at the door. "It does not do to dwell on dreams and forget to live, Harry. This mirror will be moved tomorrow. Promise me you will not seek it again."
"I promise," Harry said softly.
"Good." Dumbledore smiled. "Now — Merry Christmas."
And then he was gone, leaving only the faint scent of lemon drops and old parchment.
⸻
Harry stood before the mirror one last time. His parents smiled, their faces shining faintly through his tears.
"I'll make you proud," he whispered.
He turned away, the cloak heavy on his shoulders, and slipped silently back to Gryffindor Tower.
As he lay in bed, the last words of Dumbledore echoed in his mind.
To change the world, you must first understand it.
He wrote them down in his notebook, underlined twice.
Outside, snow drifted past the window — soft, endless, and full of promise.
