If Professor Lupin's Defense Against the Dark Arts class was a breath of fresh spring air, then Severus Snape's Potions class was a suffocating plunge into an icy, stagnant swamp. The dungeon air felt five degrees colder than usual, and the silence was so brittle it threatened to shatter at the slightest sound of a stirred cauldron.
The reason for the Potions Master's particularly foul mood was no secret. The story of Neville Longbottom's Boggart—a version of Snape wearing a vulture-topped hat and a moth-eaten lace dress—had reached every corner of the castle. It was the kind of legendary humiliation that didn't just fade; it fermented.
Now, Snape stalked the aisles like a wounded manticore. His black robes billowed behind him with predatory intent, and his eyes searched for the slightest deviation from his instructions to dock points. Anyone brave (or foolish) enough to let the name "Lupin" slip within earshot was met with a gaze so venomous it could have melted lead.
In the midst of this academic minefield, only two Ravenclaws seemed immune to the fallout.
The first was, naturally, Allen Harris. Snape had tried to bait him multiple times, hovering over his cauldron and critiquing the precise angle of his chopped valerian roots. But Allen was a machine. His movements were fluid, his timing was impeccable, and his potion was always a perfect, shimmering example of the textbook ideal. Snape eventually seemed to realize that trying to catch Allen in a mistake was a waste of his limited spite.
The second was Michael Corner. To the surprise of many, Michael had a genuine, intuitive knack for the delicate chemistry of brewing.
Since the incident where they'd stood their ground against Malfoy to protect Luna, Michael had effectively tethered himself to Allen's social circle. Allen found the dark-haired boy to be an interesting study. Michael was undeniably flamboyant—he walked with a bit of a strut and had a reputation as a serial romantic, having cycled through several "eternal loves" in the span of a few months. Yet, underneath the boasting and the girl-chasing, Michael was fiercely loyal. He had a sense of responsibility that made him a reliable ally, and in the brewing room, he was a silent, focused professional.
"He's a bit of a peacock," Allen mused one afternoon, "but at least he knows how to keep his feathers out of the fire."
With the social and academic foundations of the term settled, the time had finally come for the project Allen had been planning since the train ride: the official Ravenclaw Patronus Training.
Logistics, however, had been a hurdle. You couldn't exactly practice a Patronus without something to trigger the need for one. That's where Maggie, Allen's devoted House-elf, came in.
Through the invisible, interconnected web of the Hogwarts House-elf network, a search had been conducted. It didn't take long. House-elves saw everything that happened in the shadows of the castle.
"Master Allen, a discovery has been made!" Maggie announced one evening, popping into existence with a crisp snap. "Fanta found a squatter in the North Tower attic. A Boggart, hiding in a moth-eaten wardrobe."
She giggled, though her large eyes remained wide with a lingering trace of shock. "Fanta was very brave, Master. When she opened the door, the Boggart turned into Headmaster Dumbledore, and he... he tried to give Fanta a pair of wool socks!"
In the world of House-elves, being handed clothes was the ultimate horror—the threat of being cast out. But Fanta had channeled her inner Ravenclaw, slammed the cabinet shut, and dragged the vibrating piece of furniture all the way down to a secure room near the kitchens.
"Maggie, you and Fanta have been incredible," Allen said, truly impressed by their efficiency. "I couldn't have managed this without you."
To show his gratitude, Allen made a trip to the kitchens. He didn't go empty-handed. He brought a large hamper of specialty pastries his mother, Mrs. Harris, had sent from home. The result was a near-riot of joy. The Hogwarts elves were so touched by the gesture that they collectively vowed to keep the Ravenclaw training sessions supplied with an endless stream of hot cocoa and snacks.
By Sunday evening, the excitement in the Ravenclaw common room reached a fever pitch. At eight o'clock, the Flitwick's Charms classroom had been transformed. Desks were pushed to the walls, creating a wide, open arena. At the far end sat the old wooden cabinet, which let out an occasional, ominous thump as the Boggart within grew restless.
Penelope Clearwater took the lead, stepping onto the raised platform with the poise of a natural leader. Her long legs carried her with an aura of authority that silenced the room instantly.
"Listen up, everyone," Penelope began, her voice carrying clearly to the back of the hall. "We're all aware of the black-cloaked guests currently loitering at our gates. The Dementors don't care about school rules or house points. If they decide to wander onto the grounds, we need to be ready. After talking with Professor Flitwick and the Headmaster, we've been given the green light for this. We are here to learn the Patronus Charm."
A wave of applause broke out. Even Luna Lovegood, who usually looked like she was listening to a radio station only she could hear, was clapping with genuine focus.
Penelope raised her hands for silence. "This isn't a hobby. It's a defense. And while I'm the Head Girl, there is only one person here who has actually gone toe-to-toe with a hundred of those things and walked away. Do we agree to let Allen Harris lead this program?"
"He's the only one for the job!" Edward shouted from the second row.
"Let's make it official," Penelope said with a faint smile. "A show of hands for Allen as our Lead Instructor?"
Every single hand in the room went up. Seventh-years, who usually looked down on juniors, didn't hesitate. They had seen the reports; they knew Allen was operating on a level far beyond his age.
Allen stepped forward, offering a graceful, slightly old-fashioned bow. "I'm honored by your trust," he said, his voice calm and melodic, projecting that classic British gentlemanly charm that always seemed to put people at ease. "I promise not to waste your time."
Penelope stepped back but remained on the platform. "I'll be handling the administration. Attendance is mandatory. If you miss three sessions without a legitimate excuse, your spot goes to someone on the waiting list. And before anyone asks—no, we aren't opening this up to other houses. This is for Ravenclaw, by Ravenclaw."
"Let the Gryffindors find their own hero!" someone joked, prompting a round of laughter.
"Alright, let's get to work," Allen said, stepping into the center of the room. "Before we face the cabinet, we need to understand the enemy. Can someone tell me exactly what we're dealing with when we see a Dementor?"
To everyone's surprise, Luna's hand was the first to shoot up. Allen nodded to her.
"They are the absence of light," Luna said, her voice airy yet strangely chilling. "They don't just take your happiness; they eat the memory of it. They leave you with the coldest parts of your life, making you feel like you'll never be warm again. And if they get close enough... they take the soul through the mouth. The Kiss. It's like being a hollow shell at the bottom of the ocean."
The room went quiet. Usually, people laughed at Luna's talk of Nargles and Blibbering Humdingers, but this description was uncomfortably accurate.
"That's... remarkably well put, Luna," Allen said, nodding. "Points to Raven—oh, wait. I keep forgetting I'm not wearing the robes for that yet." He shared an awkward grin with the class, drawing a few chuckles.
Penelope stood up to add weight to the explanation. "It's important to understand the biological horror of it. As long as your heart beats, you stay 'alive' after a Kiss. But there's no you left. No thoughts, no dreams, no recognition of your friends. You're just a biological machine waiting to stop. There is no recovery from a lost soul."
The gravity of the situation settled over the younger students. The Dementors weren't just scary monsters; they were a form of spiritual execution.
"Right," Allen said, sensing the mood dipping too low. "That's why the Patronus is vital. It's a projection of everything a Dementor can't touch—pure, concentrated joy."
With a flick of his wand, a stack of parchment handouts flew from the desk, guided by precise, invisible threads of magic. They glided through the air, landing softly in the hands of every student. The seventh-years watched the display with wide eyes; most of them still struggled to move more than two objects at once with that kind of grace.
"These handouts cover the theory and the incantation," Allen explained. "Read them. Internalize the feeling. We aren't just saying words; we're building a shield out of our best memories. Take five minutes to find your 'anchor' memory. It has to be strong. It has to be real. And most importantly, it has to be happy."
As the students hunched over their papers, the classroom transformed from a room of spectators into a room of scholars, each one searching their own past for the light they would need to face the dark.
