"So, the vultures have finally decided to join the party," Allen muttered, his wand snapping up in a fluid, practiced motion.
He didn't need to shout for attention; the entire compartment was already paralyzed, every eye fixed on the nightmare in the doorway. The towering, cloaked figure seemed to sense the collective defiance. That rotted, translucent hand, which had been reaching for the door handle, suddenly twitched and vanished back into the bottomless depths of its black robes.
"Allen... what is that? What is that thing?" Hermione's voice was a thin, jagged wire of terror. She didn't realize she was doing it, but her fingers dug into Allen's arm with bruising force, jerking his wand hand downward just as he was beginning to focus.
"Dementor!" Allen hissed, trying to stabilize his aim.
But it was too late to preempt the attack. The creature tilted its hooded head back, and a long, wet, gurgling rattle echoed through the small space. It wasn't just breathing; it was feasting. It was pulling every scrap of warmth, every memory of a mother's hug or a summer breeze, out of the air and swallowing it whole.
The temperature plummeted. It wasn't just cold; it was a physical weight, a frost that started in the marrow and moved outward. Beside Allen, Harry made a horrible, strangled sound. His eyes rolled back, showing only the whites, and he crumpled from his seat like a puppet with its strings cut, his body hitting the floor and beginning to convulse in a silent, terrifying fit.
Hermione let out a strangled shriek, falling to her knees to grab Harry's shoulders. Ginny was shaking so hard her teeth were audibly chattering, her breath coming in shallow, panicked gasps. Ron had retreated into the furthest corner of the seat, hugging his knees and whimpering, "Not here, stay away, please stay away..." even as Neville stood rooted to the spot, his face a mask of sheer, helpless vacancy.
The Dementor didn't move. It stood in the threshold, slowly swiveling its hidden face from left to right, scanning the room with a sense of predatory curiosity, as if searching for a specific flavor of despair.
Allen bit his lip until he tasted copper. He needed a memory. Not just a good one, but something powerful enough to act as a shield. He thought of the first time he had successfully brewed a complex potion, the pride in his father's eyes, the warmth of the Great Hall...
"Expecto Patronum!"
A burst of silver mist exploded from his wand. It wasn't a full creature yet—more of a shimmering, ethereal shape that resembled a Phoenix in mid-flight—but it was enough. The light was blinding in the pitch-black compartment. The Dementor recoiled as if struck by physical heat, its cloak billowing as it glided backward into the corridor and vanished into the fog.
Allen slumped against the wall, his lungs burning. He didn't waste a second. Reaching into his pocket, he pulled out the slabs of Honeydukes chocolate he'd bought earlier and began breaking them into chunks.
"Eat. All of you, eat it now!" he commanded, shoving a piece into Neville's trembling hand and pressing another into Hermione's palm. He popped a square into his own mouth, and the effect was instantaneous. It was like a spark hitting a hearth; a golden warmth flooded his chest, spreading down to his numb toes and fingertips.
Just as the color began to return to Harry's deathly pale face, a piercing, high-pitched scream echoed from further down the train. It was a sound of pure, unadulterated female terror.
Allen's heart skipped a beat. He knew that voice.
He dumped the rest of the chocolate into Neville's lap. "Keep him warm. Don't let him stop eating," he barked at Hermione before charging out into the corridor.
The scene outside was a descent into hell. The narrow hallway was a sea of black cloaks. Dementors were drifting in and out of compartments like ghosts in a graveyard, their presence turning the windows into sheets of ice. And there, trapped near the junction of the next carriage, was Penelope Clearwater.
She was backed against a window, four of the soul-sucking monsters closing in on her. Her wand was out, but her hand was shaking so violently she couldn't even form a basic spark.
"Expecto Patronum!" Allen roared, his voice echoing over the howling wind outside.
This time, there was no hesitation. Driven by a fierce, protective rage, the silver mist coalesced into a brilliant, solid form. A Phoenix, its wings spanning the width of the corridor, erupted from his wand with a silent, majestic cry. It didn't just drift; it charged.
The four Dementors around Penelope didn't just retreat—they fled. They seemed genuinely terrified of the silver bird, scattering like smoke in a gale as the Phoenix circled Penelope in a protective loop of light.
Allen reached her side in three long strides, his hand catching her before she could collapse. He fumbled a piece of chocolate into her mouth, his fingers brushing her cold lips.
"Azkaban guards..." Penelope gasped, the chocolate beginning to work its magic. She clung to his arm, her knuckles white. "Allen, why are they here? They aren't supposed to leave the island!"
Allen didn't answer. He was watching the shadows. The Dementors hadn't left the train; they were regrouping. Dozens of them were drifting toward their position, drawn by the light of the Patronus. Perhaps they were angry at being denied their meal, or perhaps the rarity of a Phoenix Patronus had piqued their dark curiosity.
A dense, suffocating mass of black silk began to surge toward them.
"Allen!" Penelope shivered, the cold returning with a vengeance. The air around them began to crystallize into a thick, grey mist.
"Stay behind me, Penelope! Think of something—anything that makes you feel alive!" Allen gripped his wand until his palm hurt. He could feel the despair trying to take root in his mind, whispers of every failure and every fear he'd ever had.
"Back away! None of us are the man you're looking for. Move!"
The voice came from behind them, steady and authoritative. Professor Lupin had appeared, his own wand raised high. He looked ancient and frail in the flickering light, but his eyes were hard as flint.
The Dementors didn't budge. They seemed determined to test the limits of the wizards before them.
"Expecto Patronum!" Lupin shouted.
A silver shape shot from his wand—a wolf, lean and powerful, which began to snap at the heels of the encroaching shadows. It was a strong Patronus, but even the wolf struggled against the sheer number of Dementors now flooding the carriage.
Allen felt the fatigue deep in his bones, but he couldn't stop. "Expecto Patronum!"
The Phoenix flared back into existence, its silver feathers shedding sparks that hissed as they hit the icy floor. Beside him, he felt Penelope shift. She was no longer just clinging to him; she was standing tall, her face set in a look of grim determination.
"Expecto... Expecto..." she whispered, her brow furrowed. "Expecto Patronum!"
A wisp of silver smoke drifted from her wand, hanging like a thin veil between them. It wasn't much, but it was a start. She looked at Allen, her hand finding his. The contact seemed to ground her, injecting a final surge of warmth into her soul.
Something shifted. The silver mist from her wand didn't just fade; it began to spin, growing brighter and more solid by the second until a brilliant silver animal leaped into the air.
It was a fox. It was sleek, nimble, and blindingly bright, darting between the legs of the silver wolf and the wings of the Phoenix. The three Patronuses worked in a perfect, synchronized dance of light, driving the darkness back, inch by agonizing inch, until the Dementors finally broke. They turned and seeped through the cracks of the doors and windows, vanishing back into the rainy night.
The silence that returned was heavy, broken only by the sound of their ragged breathing. The silver fox trotted back to Penelope, looking up at her with intelligent, glowing eyes before it slowly dissolved into mist.
"A fox," Allen teased, his voice shaky but warm. "Cunning and quick. That's very you, Penelope."
Penelope laughed, a sound of pure relief, though she didn't let go of his hand. "And you? A vain, immortal bird that refuses to stay down? Pot calling the kettle black, Harris." She reached out to where the fox had been, a look of profound joy on her face.
"Remarkable," Professor Lupin said, stepping forward. He was leaning slightly against the wall, looking even more exhausted than before, but his gaze was fixed on Allen.
"Professor? Is something wrong?" Allen asked, feeling a strange weight in the man's stare.
"To produce a corporeal Patronus at thirteen is... unheard of," Lupin said softly. "But that's not what strikes me most." He paused, his eyes reflecting the dim light of the corridor lamps. "In the modern world, I only know of one other wizard whose Patronus takes the form of a magical creature. Albus Dumbledore. And his, as you might know, is also a Phoenix."
Lupin took a step closer, his expression solemn. "A Phoenix doesn't just represent light, Allen. It represents rebirth, sacrifice, and a power that cannot be extinguished. Dumbledore is the greatest wizard of our age. To share that symbol with him... it says a lot about what you might become."
Penelope beamed, her eyes shining with a pride that was almost proprietary. She had never doubted Allen's trajectory, but hearing it from a Professor—from a man who clearly knew his way around a wand—was the ultimate validation.
Allen's smile was modest, though his mind was racing. He'd heard similar things from Ollivander when he'd first held his wand. Part of him wondered if all great wizards were just told what they wanted to hear to keep them on the path of the 'Light,' but looking at Lupin's honest, tired face, he decided to take the compliment at face value.
"Thank you, Professor," Allen said gently. "I'll try to live up to the comparison. But for now, I think we all just need more chocolate."
