The morning of December 24th dawned crisp and bright over Hogwarts, the kind of winter day that made the castle's ancient stones gleam like polished marble under a thin dusting of snow. Students hurried through the corridors with flushed cheeks and excited chatter, their breath forming little clouds that mingled with the floating candles. For most, today was the last full day before the Christmas holidays, but for Sullivan and his growing inner circle, it was something far more significant—the official launch of the Magic Phone to the wizarding public.
Sullivan stood in his office, adjusting the collar of his formal professor robes. The dark fabric was embroidered with subtle silver runes that caught the light, a custom touch he had added himself. In his hand, he held the very first mass-produced unit, its sleek black casing warm from the enchantment that kept the battery charged. The screen glowed softly with the Flying Feather logo—a single black raven feather that shimmered with iridescent hues when tilted.
Tonks watched him from the doorway, her hair a vibrant shade of festive green streaked with silver tinsel. She wore her Auror robes open over a casual sweater, the anti-curse ring still gleaming on her finger. "You look nervous," she teased, stepping inside and closing the door behind her. "The man who faced a vampire count and built an empire in six months is nervous about selling phones?"
Sullivan chuckled, but there was a flicker of genuine tension in his eyes. "It's not the phones. It's everything that comes after. Once this launches, there's no going back. The Ministry will want answers, the pure-blood families will sniff around for profit, and Voldemort's people will start paying attention. We're lighting a match in a room full of fireworks."
Tonks crossed the room and slipped her arms around his waist, resting her chin on his shoulder. "Then we'll handle the fireworks together. You've got me, Yuna, Lupin, Teemo, and the kids in Raven's Feather. Plus, Dumbledore's watching your back—for now."
He turned and kissed her forehead, savoring the familiar scent of her shampoo mixed with the faint ozone of her recent Auror training. "You're right. Let's make history."
Down in the Great Hall, the Christmas Eve feast was already underway, but the usual holiday cheer had an extra layer of buzz. Word had spread like Fiendfyre that Professor Sullivan would be demonstrating the Magic Phone publicly after dinner. Students from every house were whispering, some clutching small pouches of Galleons they had saved or borrowed from parents. Even the ghosts were floating closer than usual, their translucent forms flickering with curiosity.
At the staff table, Dumbledore sat with his usual serene smile, but his eyes held a spark of genuine interest. McGonagall was chatting animatedly with Flitwick, both clearly excited about the new communication tool that had already revolutionized their staff meetings. Snape, as always, looked like he had swallowed a lemon, but even he couldn't hide the faint curiosity in his gaze whenever Sullivan's phone buzzed with a new message. Sprout was showing Pomfrey a small potted plant that could be monitored remotely via the device, and Hagrid was practically bouncing in his oversized chair, boasting to anyone who would listen that he had been one of the first to test it.
Sullivan took his seat, and the hall gradually quieted as students noticed him. He waited until the desserts had been served—Christmas puddings, mince pies, and treacle tart—before standing. A simple Sonorus charm amplified his voice across the vast room.
"Students, staff, and friends," he began, "tonight marks the beginning of something that will change how we connect as witches and wizards. For centuries, we've relied on owls for messages, Floo powder for urgent talks, and patience for everything else. Today, that changes."
He held up the Magic Phone, and the screen projected a massive holographic display above the staff table. Gasps and murmurs filled the hall as students saw their own faces reflected back at them in real time. Sullivan tapped the screen, and the image switched to a live feed from the Raven's Feather group chat.
"Meet the Magic Phone," he continued. "It lets you send instant messages, share photos and short videos, and soon—play games with friends across the country. No more waiting days for an owl to arrive. No more hoping your letter doesn't get lost in a storm. This is communication at the speed of magic."
He opened the FlyMessage app and typed a quick note: "Happy Christmas Eve, Hogwarts!" The message appeared on the projection, and every student who had already received a prototype phone (mostly Raven's Feather members and a few early testers) felt their devices buzz. Cheers erupted as they showed their friends the live message.
Fred and George stood on their bench, waving their phones like trophies. "We helped build the chess game!" Fred shouted. "You can play against anyone with a phone—right now!"
The hall exploded with excitement. Even the Slytherins, usually more reserved, were leaning forward with interest. Gemma Farley, sitting with her house, looked radiant as she demonstrated the device to a group of curious fourth-years. Cedric Diggory was showing Hufflepuffs how to take photos, and Alice Lavine was quietly explaining the basics to a cluster of Ravenclaws.
Dumbledore stood, his voice calm but carrying the same magical amplification. "A most remarkable invention, Professor Sullivan. I believe this will bring our world closer together in ways we have never imagined. Ten points to Ravenclaw for innovation and forward thinking."
The Ravenclaw table cheered loudly, but the real celebration was just beginning. Sullivan had arranged for a limited number of phones to be sold right there in the Great Hall—fifty units at the introductory price of forty-five Galleons each. The line formed almost instantly, stretching from the staff table all the way to the doors. Students from every house jostled for position, Galleons clinking in their pockets.
Sullivan, Lupin, and Teemo had set up a small booth near the entrance. Teemo, dressed in his sharp green explorer outfit, handled the transactions with surprising efficiency, his tiny hands flying as he counted coins and handed over the devices. Lupin managed the line, keeping order with his calm, authoritative presence. Sullivan himself demonstrated the phones to the first buyers, answering questions and showing off features like the camera and group messaging.
A young Gryffindor girl named Lavender Brown was one of the first in line. She clutched her Galleons tightly, eyes wide. "Professor, can I really talk to my friends in Hufflepuff without waiting for an owl?"
"Instantly," Sullivan confirmed, showing her how to add contacts. "And you can send photos too. Here—take a picture of the hall and send it to your friend."
Lavender did so, and when her Hufflepuff friend's phone buzzed a moment later with the image, the girl squealed with delight. The excitement spread like wildfire. Within an hour, all fifty units were sold, and students were already forming groups to play with their new devices.
As the feast wound down, Sullivan stepped aside to check his own phone. Messages were pouring in from across Britain and even a few from America via the limited international connection he had set up with Yuna's help. Stewart had sent a short note: "Phones are flying off the shelves here. MACUSA wants another five hundred by New Year. Name your price."
Sullivan smiled and replied: "Two hundred for now. We're still scaling production. Focus on building the network infrastructure—servers, repeaters, security. The hardware is just the beginning."
Yuna's message came next, accompanied by a photo of her in her Auror robes, holding up one of the phones with a proud grin. "The American launch party is set for next week. Stewart wants you here in person. I want you here too. Miss you, Su."
He typed back quickly: "I'll be there. Save me a dance—and a private moment after the party."
Her reply was instant: a string of heart emojis and a single word: "Promise."
Tonks, who had been helping at the sales booth, slipped her arm through his as the last students filtered out. "You did it," she said softly, her hair shifting to a soft rose gold that matched the holiday lights. "They love it. The whole school is buzzing."
Sullivan pulled her close, kissing the top of her head. "We did it. But this is only the beginning. Tomorrow, the real work starts—expanding the network, securing partnerships, and keeping an eye on Quirrell. Voldemort won't stay quiet forever."
Tonks nodded, her expression turning serious for a moment. "I'll be right beside you. And Yuna too, when she's here. We've got your back."
They walked together through the emptying hall, the floating candles dimming as the house-elves began to clear the tables. In the distance, students were still clustered in groups, heads bent over their new phones, laughing and chatting in real time. The wizarding world was changing, and Sullivan was at the center of it.
Later that night, in the privacy of his office, Sullivan sat at his desk with the Moonstone server orb floating before him. The unicorn blood inside glowed steadily, powering the nascent network. He had connected fifty test devices so far—mostly Raven's Feather members and a few trusted professors—and the system was holding stable.
He opened the admin panel and began refining the code. Security was the top priority. He added layers of encryption using ancient rune sequences that even Dumbledore would have trouble cracking. Then he expanded the app store, adding a simple news feed that pulled from the Daily Prophet and other sources. It was crude, but it was a start.
A soft knock interrupted him. Tonks slipped inside, wearing nothing but one of his spare shirts. "Still working?" she asked, her voice low and inviting.
Sullivan set the orb aside and pulled her onto his lap. "The network can wait a few hours. Right now, I need to celebrate properly."
She kissed him deeply, her hands sliding under his robes. The night passed in a blur of passion and whispered promises, the Magic Phone forgotten on the desk as they lost themselves in each other.

The next morning, Sullivan woke early. Tonks was still curled against him, her hair a soft lavender in the morning light. He slipped out of bed carefully, dressed, and headed to the factory in Hogsmeade.
Lupin and Teemo were already there, overseeing the morning shift. Production was steady at thirty-eight phones per day, and the stockpile was growing. Sullivan checked the quality of the latest batch, then sat down with Lupin to discuss expansion.
"We need more workers," Lupin said. "The current team is stretched thin. I've got a list of reliable people—some Muggle-borns, some half-bloods who need steady work. They're good with their hands and loyal."
Sullivan nodded. "Hire them. Double the shifts if you have to. We'll need at least a hundred units a day by January if we want to meet the American demand."
Teemo, who had been polishing a finished phone, looked up. "Master, Teemo can help more. Teemo is strong with cleaning charms and can keep the factory spotless so no dust interferes with the runes."
Sullivan ruffled the little elf's head. "You're already doing more than enough, Teemo. But if you want to take on more responsibility, I won't stop you. Just remember—you're free. You can choose your own path."
Teemo's eyes shone with gratitude. "Teemo chooses to stay with you, Master. Teemo is happy here."
The morning passed in productive chaos. By noon, Sullivan had approved the hiring of fifteen new workers and finalized the design for a second production line. The factory was no longer a small operation—it was becoming a true industrial hub for magical innovation.
As he prepared to return to Hogwarts for afternoon classes, a message from Rita Skeeter arrived: "Article is ready. Front page tomorrow. You're going to be famous, boss."
Sullivan smiled. The pieces were falling into place faster than he had anticipated. The Magic Phone was no longer a prototype—it was a revolution. And he was only getting started.

Back at the castle, Sullivan found himself surrounded by students the moment he stepped into the corridors. News of the launch had spread like wildfire, and everyone wanted to know more. He answered questions patiently, demonstrating features and promising that more units would be available after the holidays.
In the staff room, the other professors were buzzing about the device. Flitwick was already using his to coordinate Charms club meetings, and Sprout had set up a group for greenhouse schedules. Even McGonagall admitted it was "remarkably efficient" for sending notices to the Gryffindor common room.
Snape, of course, was the exception. He stood in the corner, arms crossed, watching the excitement with his usual scowl. Sullivan approached him, holding out a phone.
"Peace offering," Sullivan said. "No strings attached. You can use it to coordinate with the other Heads or just ignore it completely. Your choice."
Snape stared at the device for a long moment, then took it with a grunt. "If it explodes, I'm blaming you."
Sullivan laughed. "Fair enough. But try sending a message to the staff group. It might make your life easier."
Snape pocketed the phone without comment, but Sullivan noticed the faint twitch of his lips. Progress.
The rest of the day passed in a blur of classes and planning. Sullivan taught his Muggle Studies lesson on modern communication technology, using the Magic Phone as a living example. The students were rapt, taking notes and asking questions that showed real engagement.
That evening, as the castle settled into a peaceful quiet, Sullivan sat in his office with the Moonstone server floating before him. He had increased its capacity again, and now it could handle up to two hundred devices without strain. The network was growing, and so was his influence.
A soft knock at the door announced Tonks. She entered, carrying a tray of food from the kitchens. "You skipped dinner again," she scolded lightly. "Eat something before you turn into a ghost like Binns."
Sullivan pulled her onto his lap, kissing her deeply. "I've got a better idea for dinner."
The night passed in warmth and laughter, the Magic Phone forgotten on the desk as they lost themselves in each other. Outside, snow began to fall softly over Hogwarts, blanketing the castle in a peaceful white. The wizarding world was on the cusp of change, and Sullivan was the one guiding it.

The days leading up to Christmas were a whirlwind. Production at the factory reached forty units per day, and the stockpile grew steadily. Sullivan spent his spare time refining the network server, adding security layers and testing new features with the Raven's Feather team.
On Christmas Eve, the official launch finally arrived. Sullivan stood in the newly expanded Flying Feather Experience Store in Hogsmeade, surrounded by a crowd of eager witches and wizards. The store had been transformed into a festive wonderland, with floating lanterns, enchanted snow falling gently from the ceiling, and a large projection screen showing the Magic Phone in action.
Lupin and Teemo handled the sales, while Sullivan gave a short speech. "This is more than a device," he said. "It's the beginning of a connected world. Welcome to the future."
The crowd cheered as the first customers stepped forward. Phones flew off the shelves faster than they could be stocked. By the end of the day, every unit was sold, and orders for the next batch were already pouring in.
As the sun set, Sullivan stepped outside for a moment of quiet. Tonks joined him, slipping her hand into his.
"You did it," she said softly.
"We did it," he corrected, pulling her close.
In the distance, the lights of Hogwarts twinkled like stars. The castle stood as it had for centuries, but the world around it was changing. Sullivan looked up at the sky, the first stars appearing, and felt a quiet sense of purpose.
The revolution had begun. And he was only getting started.
