November 28, 1992.
Curfew had settled over Hogwarts like a heavy, velvet shroud. In the high reaches of the castle, the torches burned with a low, rhythmic pulse, their flames turning a deep, molten gold as they fought back the encroaching chill of the Scottish winter. Most of the heavy oak doors were shut tight, and the portraits dozed within their gilded frames, occasionally muttering in their sleep or shifting positions in their painted beds.
Orion Blackheart moved through the corridors with the silent, predatory grace of a creature that had spent its childhood in the literal shadows of Knockturn Alley. Behind him, four shadows followed, their footsteps echoing with a frantic, uneven rhythm against the ancient stone.
Tobias Finch was whispering far too loudly, his voice vibrating with a mix of excitement and sheer terror. "I still don't understand how you found a place like this, Orion. I've spent two months mapping the third floor and I haven't seen so much as a hidden broom closet."
"I didn't 'find' it, Tobias," Orion replied, his voice a calm, resonant anchor in the dark. "The castle provided it."
"That sounds extremely suspicious," Tobias snorted, nearly tripping over the hem of his robes.
Elliot Moor glanced nervously over his shoulder, his eyes wide behind his glasses. "If Filch or Mrs. Norris catches us this far from the tower, we're dead. I can already feel the points leaving the hourglass."
Cassian Rowle scoffed quietly, his hands stuffed into his pockets. "You worry far too much, Elliot. Fear is a waste of metabolic energy."
"I worry the exact correct amount for a first-year wandering the halls after midnight," Elliot insisted.
Adrian Shah walked beside Orion at the front of the group, his analytical mind already cataloging the route. "You're certain this room exists as a physical space? Not just a localized hallucination?"
"Yes," Orion said.
"And it manifests based on specific requirement?"
"Precisely."
They turned a corner on the seventh floor and arrived at a long, seemingly empty corridor. On the opposite wall hung a massive, somewhat absurd tapestry of Barnabas the Barmy, who was depicted in a frozen state of panic while attempting to teach a group of very confused trolls how to perform a ballet.
Tobias blinked, staring at the woven threads. "…Why are the trolls wearing tutus? Is that a historical fact?"
"Focus," Cassian muttered, nudging him forward.
The wall across from the tapestry was a blank expanse of stone—no door, no handle, no visible seam. Elliot looked around, his heart rate audible in the silence. "Orion? There's nothing here but dust and bad art."
Orion didn't answer. He simply began to walk. He focused his mind on the need for a sanctuary—a place to train, a place where the "Alliance" could sharpen its teeth away from the prying eyes of the staff. He walked past the blank wall once. Then he turned and walked past it again, his Starfall Yew wand humming in his pocket in resonance with the castle's ancient magic.
On the third pass, the stone began to shift. With a low, grinding sound that felt like a tectonic plate moving, a heavy wooden door slowly manifested in the center of the wall.
"…Okay," Tobias whispered, his jaw dropping. "That is the coolest thing I've ever seen. Hogwarts is a miracle."
Orion pushed the door open. Warm, golden light spilled out into the cold corridor. Inside was an enormous, vaulted chamber that seemed to defy the physical dimensions of the tower. High, arched ceilings were lit by floating lanterns that cast a soft, steady glow. The floor was a smooth, polished stone, marked with three large, circular dueling platforms. Racks of practice equipment lined the walls—shields, training dummies, and enchanted targets that drifted lazily through the air like captive ghosts.
Cassian stepped inside, his dark eyes Scanning the room with a grim, strategic approval. "This is… perfect. A fortress within the school."
"Then we should use the time wisely," Orion said, stepping onto the central dueling platform.
The sparring began with a frantic energy. Tobias was the first to draw his wand, his sandy hair messy with excitement. "Flipendo!" he shouted, firing a blue-white jolt of kinetic energy.
Orion shifted his weight, a micro-adjustment of his hips that let the spell skim past his shoulder with an inch to spare. "Too direct, Tobias. You telegraph your intent with your shoulders."
His wand flicked—a sharp, lazy movement. "Rictusempra."
the charm struck Tobias in the chest, the silver flash knocking him backward onto the padded edge of the platform. "I wasn't ready!" he protested, laughing and gasping for air simultaneously.
Cassian stepped forward, his style much sharper. He fired a rapid sequence of jinxes—Stupefy, Expelliarmus, and a stinging hex that moved with vicious speed. Orion responded smoothly, his motions economical and fluid. He didn't waste energy on large movements; he used the "current" of the room to pivot. Eventually, with a perfectly timed disarming charm, Cassian's wand was plucked from his hand as if by an invisible bird.
Adrian was next. He bowed with a scholar's grace, and Orion returned the gesture. Their duel was a masterpiece of control. Spells cracked together in mid-air, flashes of red and blue light bouncing off the stone walls like trapped lightning. Elliot watched with wide eyes, while Tobias sat on the floor, somehow having acquired a biscuit from the folds of his cloak.
"Ten sickles on Orion," Tobias said, munching happily.
"You're betting on the obvious outcome," Cassian noted, watching the way Orion's silver eye seemed to track the spells before they were even cast.
As the clock neared one in the morning, the far wall of the chamber began to shimmer. The Room of Requirement, sensing the need for a greater challenge, began to shift the stone.
Three figures appeared on the opposite platform. They weren't people; they were magical simulations, perfectly formed and terrifyingly still. Professor McGonagall. Professor Flitwick. And Professor Snape.
The simulated Snape stepped forward. Even as a construct of magic, his expression was one of cold, academic disdain. He raised his wand in a stiff, predatory line.
"Oh, this should be good," Cassian whispered, his arms crossing.
Orion stepped onto the platform again. He felt the Thunderbird static rising in his blood, the "Star-blessed" energy of the Starfall Yew wand vibrating in his palm.
"Begin," the room seemed to whisper.
The simulated Snape moved first. "Sectumsempra—no, a cutting hex," Orion corrected himself mid-thought. The red beam shot forward with vicious speed.
Orion didn't use a standard Protego. He reached into the celestial architecture of his mind. "Aegis Astra!"
A shield blossomed in front of him. It wasn't a translucent blue dome; it was a fragment of the Night Sky. A thin, shimmering plane of starlight formed in the air, deep indigo and flecked with tiny, glowing sparks of white. When the cutting hex struck it, the spell didn't just stop; it was absorbed into the "nebula" of the shield and scattered like harmless dust.
Tobias blinked, nearly dropping his biscuit. "…Did he just conjure a galaxy?"
The Snape-construct attacked again. A rapid-fire Stupefy followed by a localized atmospheric hex. The simulation fought like a master, relentless and precise. Orion stepped back as another shield formed—this one thinner but brighter, threads of silver light weaving together like the constellations of a star-map.
Celestial Shielding (Aegis Astra): Unlike traditional defensive magic which creates a physical or energetic barrier, celestial shielding creates a localized "void." The incoming spell is not blocked, but rather "lost" within the astronomical distance simulated by the caster's mindscape.
For several minutes, the air in the Room of Requirement crackled with the violence of the duel. Orion was matching the rhythm—spell, shield, counter-strike. The silver veins in his wand were glowing with an intense, pulsing light.
Then, the Snape-simulation changed tactics. It used a feint, a weak jinx that forced Orion's shield to flare bright white, and then slipped a high-velocity Stunning Spell past the edge of the barrier.
Orion twisted, but he was a fraction of a second too slow. The red light struck him square in the chest. He was thrown backward, sliding across the polished stone as his celestial light dissolved instantly.
Silence filled the room. The simulated professors vanished back into the stone. Orion sat up slowly, rubbing his chest where the spell had impacted.
Cassian let out a low, appreciative whistle. "You lasted longer than I expected. You actually held the line against a master simulation."
"You almost had him," Tobias grinned, helping Orion to his feet.
"Almost," Adrian corrected calmly. "But the failure was in the transition between the shield and the counter. The starlight takes a moment too long to recalibrate."
Elliot looked amazed. "Orion... that shield. I've never seen magic that looked like that. It looked like... like the Astronomy Tower."
Orion brushed the dust from his robes, his expression neutral, but his mind was already replaying the duel in slow motion. He saw the exact millisecond where his defense had fractured. He felt the weight of the Starfall Yew and the way it had hungered for more power.
"I need to work on the anchor points," Orion said quietly. "If the stars move, the shield moves. It needs to be stationary."
The boys gathered around him, their curiosity overriding their exhaustion. They had seen something tonight that wasn't in the textbooks.
As they slipped back through the darkened corridors toward Ravenclaw Tower, their footsteps echoing in a synchronized, purposeful rhythm, Orion looked up through a window at the real sky. The stars above shimmered in quiet approval.
He hadn't won the duel, but he had survived it. And in a world where the Chamber of Secrets was open and the "Ending" was hunting, survival was the only grade that mattered.
"Next week," Orion whispered to the dark. "We go again."
