Harry Potter and the Deep Freeze

The Work Begins

The sun was high over the sanctuary as Harry and his team gathered inside Nigrum Anima, the new black building that had appeared overnight. Its sleek, foreboding architecture still felt out of place within the golden glow of the dome, but its purpose was unmistakable: to push their research forward.

Around the large central hall, the specialized experimental rooms hummed faintly with magic, ready for use. Each sample retrieved from the Black Tower had been carefully placed in its designated space, waiting to reveal its secrets.

Harry stood at the center of the hall, his gaze sweeping over his gathered team: Luna, Neville, Draco, Fred, George, and Dudley.

"This is it," he began, his voice firm but calm. "We don't know why the dome created this building, but it's clear what it expects us to do. The Black Tower is tied to the frost, and these samples are tied to the tower. If there's any way to figure out what's coming—or how to stop it—it starts here."

Dividing the Tasks

Harry gestured toward the first experimental room, where the crystals from the tower were arranged on rune-covered pedestals.

"Neville, Luna, you'll focus on the crystals," he said. "Try to determine how they're connected to the magic of the tower—and what they can do."

Neville nodded, already flipping through a notebook filled with sketches and observations. "We'll start with resonance testing. If they're amplifying or releasing magic, we might be able to track their energy flow."

Luna smiled faintly. "And if they're holding secrets, we'll uncover them."

Harry turned to Draco. "You'll take the goblin blood and tendrils. Figure out if they're alive or if they're being sustained by the tower's magic."

Draco raised an eyebrow. "Dissecting strange magical materials isn't exactly my specialty, Potter."

"You're the best we've got for precision," Harry said firmly. "And I trust you to handle it."

Draco smirked. "Flattery will get you everywhere."

"Fred, George," Harry continued, looking to the twins. "The black vines are yours. See if you can isolate the mist they release and figure out its purpose."

Fred saluted. "You've got it, boss."

"And don't blow anything up," Harry added, eyeing them sternly.

"No promises," George said with a grin.

Finally, Harry turned to Dudley. "You'll help me with the structural samples—the moss, the stone, and anything else connected to the tower itself. If we understand how it was built, we might understand why it's here."

Dudley nodded, looking more confident than he had before. "Let's get to work, then."

The Crystal Lab

In the crystal lab, Neville and Luna carefully arranged their samples on a circular rune-carved table.

Neville tapped his wand against one of the crystals, sending a faint spark of light across its surface. The crystal glowed in response, its light rippling outward like a pulse.

"It's absorbing and amplifying magic," Neville said, jotting down notes. "But it's not storing it. It's releasing the energy back into the air."

Luna tilted her head, watching the light fade. "It's like it's breathing," she said softly. "Taking in magic and exhaling it."

Neville frowned. "If the tower is full of these, they might be part of its power source—or its defenses."

"Or both," Luna added. "Let's see how they respond to other spells."

The Blood and Tendrils

In the creature lab, Draco carefully examined a vial of goblin blood under an enchanted magnifier. The green liquid writhed faintly, as though still alive.

"It's reacting to magic," Draco muttered, frowning. "The more energy I direct at it, the more it moves. It's almost... parasitic."

He turned to the tendrils, which coiled faintly in their containment jar. Using enchanted gloves, he extracted one and placed it under a diagnostic charm.

The tendril twitched as the spell took effect, its faint glow pulsing in response.

"These things are feeding off the tower's magic," Draco realized. "They're symbiotic—part of the tower's ecosystem."

The Black Vines

Fred and George were in their element in the alchemical lab, poking and prodding at the black vines that exuded their strange mist.

"Careful with that," Fred said as George used a pair of enchanted tongs to hold a thorny segment over a flame.

The mist shimmered in the air, refracting light like a prism.

"It's not toxic," George said, leaning closer. "But it's definitely enchanted. Watch this."

He waved his wand through the mist, and the air around it froze briefly before returning to normal.

"It's reacting to heat and movement," Fred said. "Probably meant to slow down anything that gets too close."

"Think we can weaponize it?" George asked, grinning.

"Let's isolate it first," Fred replied. "Then we'll talk."

The Structural Samples

In the resonance chamber, Harry and Dudley examined the glowing moss and pieces of the tower's stone walls.

"The moss is radiating low-level magic," Harry said, holding a diagnostic orb over the sample. "It's like a magical battery, storing energy over time."

"And the stone?" Dudley asked, pointing to a shard of the dungeon wall.

Harry placed the shard on a rune-covered platform, which pulsed faintly in response. The stone began to glow, its surface rippling with energy.

"It's alive," Harry said quietly. "The tower isn't just a building—it's a living construct. Everything inside it is part of a system."

Dudley frowned. "So, the tower's not just a dungeon. It's... growing?"

"Maybe," Harry said. "Or maybe it's preparing for something. Either way, we need to figure it out before it's too late."

The Magical Vehicles in Action

Meanwhile, outside the Nigrum Anima, Fred and George took one of the magically powered carts for a test run.

"These things are brilliant," Fred said as the cart glided smoothly over the sanctuary's grounds.

"They're fast, quiet, and enchanted to carry heavy loads," George added. "Perfect for hauling samples—or sneaking around."

The cart hummed softly as it returned to the entrance of the Nigrum Anima, where Fred and George jumped out with wide grins.

"Best invention yet," Fred said.

"Let's see if we can make them fly," George suggested.

"Not yet," Harry said, stepping outside with a faint smile. "Let's figure out the Black Tower first."

As the day wore on, the team continued their work, the samples revealing fragments of the Black Tower's secrets. The Nigrum Anima had become the heart of their research—a place where magic and science met to confront the unknown.

But as Harry stood in the resonance chamber, watching the stone shard glow faintly under his spell, he couldn't shake the feeling that the tower was watching them in return.
