May 7, 1993.
The Ravenclaw common room had become a tomb of scholarship. It was nearly midnight, and the usual hum of intellectual debate had long since surrendered to a heavy, suffocating silence. The fire in the marble hearth had burned down to a rhythmic, dying orange pulse, throwing skeletal shadows against the stone walls that looked like reaching fingers. Outside, the silver light of a Gibbous moon filtered through the tall, arched windows, painting the blue velvet armchairs in ghostly, desaturated hues.
We were scattered around one of the large circular study tables, a scene of academic and physical exhaustion. Tobias Finch had a massive volume on Medieval Hex-Breakers open in front of him, but his chin was resting in his palm, and his eyes were glazed over with a look of profound boredom. Elliot Moor was already lost to the world, his head pillowed on his arms, his soft snores the only rhythmic sound in the room. Cassian Rowle was leaning back in his chair, lazily flipping a silver sickle between his knuckles—clink, clink, clink—the sound of a strategic mind idling.
I sat slightly apart, my back straight, reviewing a stack of potion notes from the latest Potions Club session. But my mind wasn't on the ratios of moonstone to hellebore. My "Thestral-sight" was active, and I could feel the "Endings" vibrating in the masonry. The castle was screaming in a frequency only I could hear.
Adrian Shah was not at the table. He had been missing for six hours, buried somewhere in the deepest recesses of the library.
Tobias let out a long, theatrical sigh that practically ruffled the pages of his ignored book. "I'm telling you, Orion... we're wasting our time. We're chasing a ghost that doesn't want to be found."
Cassian didn't stop the coin's movement. "Doing what, Tobias? You haven't turned a page in forty minutes."
"Thinking!" Tobias shot back. "I am thinking about how much I hate mysteries that don't involve a reward. We've been trying to solve the puzzle of the Chamber for months, and we still have exactly zero data points that make sense."
Elliot let out a muffled groan into his sleeve without lifting his head. "I second the motion. The thinking is currently causing a localized headache."
"Adrian is still out there," I noted, my voice sounding older than the boy sitting in the chair. "He doesn't waste energy on lost causes. If he's still researching, there is a thread to pull."
Tobias rubbed his face, his sandy hair standing up in frantic tufts. "That's exactly what worries me. Adrian's 'threads' usually lead to five-hundred-page essays and a distinct lack of sleep."
The heavy oak door of the common room groaned open.
Adrian Shah stepped inside. He didn't look like a student who had just spent six hours in a library; he looked like a man who had just finished mapping a battlefield. He wasn't tired. He was Target-Locked. His arms were full of books—massive, leather-bound tomes that looked like they hadn't been checked out since the seventeenth century.
Cassian's coin-flipping stopped. He sat up, his dark eyes narrowing. "…Well, that looks ominous. Did you find the library's obituary section, Adrian?"
Adrian crossed the room without responding, his boots striking the stone with a rhythmic, purposeful sound. He reached the table and dropped the stack.
THUD.
The impact was heavy enough to make the inkwells rattle. Elliot jerked awake with a yelp of alarm, nearly falling out of his chair. "What—is it the monster?! Is it here?!"
Adrian sat down, pulled the top book toward him, and opened it to a heavily bookmarked page. His expression was one of absolute, clinical certainty.
"I believe," Adrian said, his voice a low, vibrating frequency, "I finally know what the 'Monster' in the Chamber of Secrets is."
The atmosphere at the table shifted instantly. The exhaustion vanished, replaced by a sharp, predatory focus. Even the air in the common room seemed to grow colder as we leaned in.
Adrian turned the book around so the rest of us could see.
Spanning across the two-page spread was an illustration of a nightmare. It was a serpent, but one of impossible proportions. Its scales were depicted as thick as dragon-hide, a deep, necrotic green. Its head was crowned with a series of jagged, bone-like ridges, and its eyes... even in the drawing, the eyes were a terrifying, glowing amber.
Tobias frowned, his bravado wavering. "…A snake? We're being hunted by a giant garden snake?"
Adrian shook his head, his finger tapping the title at the top of the page. "A Basilisk."
I felt a sharp prickle along my spine. My "Deers of Death" intuition flared—a recognition of a predator that sat at the apex of the void.
"The Basilisk is one of the most dangerous magical entities ever recorded," Adrian continued, his tone that of a professor giving a lecture on a death-curse. "It is an 'Artificial Apex Predator.' Traditionally bred by hatching a chicken's egg beneath a toad. It is a biological weapon of the Dark Arts."
Elliot blinked, his face turning grey. "That sounds... that sounds like something the Ministry would have a lot of paperwork against."
"It's a Class A non-tradeable creature, Elliot," Cassian noted, his pureblood training surfacing. "Having an egg is an automatic sentence in Azkaban. But how dangerous is it? Really?"
Adrian flipped to a section titled Ocular Terminations. "Direct eye contact with a Basilisk doesn't just blind you, Cassian. It causes Instantaneous Biological Cessation. Total termination of the life-force. You don't even have time to scream."
The table went silent. Tobias stared at the illustration as if it might lung off the page. "…Well, that is officially the most horrifying thing I have ever heard. Why aren't we all dead? If there's a giant 'Instant-Death' snake wandering the halls, why are there only statues in the infirmary?"
Elliot sat up straighter, his mind finally catching up to the logic. "Orion... Adrian is right. Why are they only petrified?"
Adrian opened a second book—a smaller, more modern volume on Magical Optics—and laid it beside the first.
"Because," Adrian said, his eyes gleaming behind his glasses, "no one has actually looked the monster in the eye. Not directly."
He began to list the attacks, his voice counting down the variables of a lethal equation.
"Colin Creevey. He was holding his camera. He didn't look at the snake; he looked at the viewfinder. The lens and the silver-nitrate of the film acted as a filter. It turned a 'Termination' into a 'Suspension'."
Cassian nodded slowly, the pieces of the puzzle clicking into place. "That explains why the camera melted. It took the brunt of the magical discharge."
"Justin Finch-Fletchley." Adrian continued. "He saw it through Nearly Headless Nick. The Basilisk's gaze passed through the semi-transparent essence of a ghost first. It weakened the signal. Justin was petrified, and the ghost... well, he's already dead. He just absorbed the energy and went into stasis."
Tobias blinked, looking impressed despite his fear. "…So Justin got lucky because a dead man was standing in the way."
Adrian nodded. "And Hermione Granger." He slid a piece of parchment across the table—a copy of a nurse's log. "I checked the reports from Madam Pomfrey. Hermione was found holding a small hand-mirror. She was using it to look around corners. She saw the reflection, not the source."
Elliot stared at Adrian in awe. "You figured all of that out? From the library?"
"The data was there," Adrian said. "It just needed a framework."
I leaned forward, my silver eye reflecting the orange embers of the fire. "And the girl from 1943, Adrian? Did you find the 'Ending' that started the cycle?"
Adrian opened the final book—the oldest one in the stack. Its pages were yellowed and smelled of damp earth and funeral incense. "Fifty years ago, one student died. A girl named Myrtle Warren."
Cassian squinted at the name. "…Myrtle? That sounds familiar. Isn't that the name of the girl who haunts the second-floor bathroom?"
Tobias's eyes widened. "Moaning Myrtle! The one who throws water at everyone!"
"Yes," Adrian said grimly. "She died in that bathroom fifty years ago. Hagrid was blamed, but the cause was never officially recorded. If you ask her... I suspect she'll tell you she saw a pair of big, yellow eyes near the sink."
Silence fell over the table once more. We looked at each other—five boys who had just realized they were living in a hunting ground.
Elliot slowly leaned back, his voice a shaky whisper. "So... let me get this straight. There is a sixty-foot death-snake living in the walls of the castle. It's been there for a thousand years. And it's been hunting us since October."
Adrian nodded. "And the most important part? It travels through the Plumbing."
Cassian rubbed his chin, his strategic mind visualizing the castle's architecture. "The pipes. That's how it gets between floors so fast. It doesn't need the corridors."
"The plumbing system is the nervous system of the castle," I added quietly. "It connects every room, every floor, every dungeon. We are essentially living inside the monster's burrow."
Tobias let out a long, jagged groan. "Fantastic. Absolutely brilliant. Hogwarts is basically a giant snake-tunnel. I am never going to the bathroom again. I'm just going to hold it until June."
Cassian smirked, but it was a cold, sharp thing. "Look on the bright side, Tobias. At least we know what to look for now. A mirror isn't just for vanity anymore; it's a life-saving device."
"There is no bright side to a giant death-serpent, Cassian!" Tobias hissed.
Adrian closed the heavy books with a final, echoing thud. "There is one final detail we cannot ignore."
We all looked at him.
"A Basilisk of that age and power does not act on its own," Adrian said, his voice dropping to a conspiratorial level. "It is a bound creature. It requires a command. It requires a Speaker."
I felt the "Deers of Death" within me recognize the finality of the statement. The beast was the weapon, but there was a hand on the trigger.
"Someone is controlling it," I whispered. "The Heir of Slytherin."
The fire crackled one last time and died, leaving the room in the cold, silver light of the moon. Outside, the dark waters of the Black Lake pressed silently against the castle walls. And somewhere deep beneath our feet, within the lead pipes and the ancient stone, something enormous was moving.
It was hunting. And now, we knew its name.
The Alliance sat in the dark, five silhouettes against the stars, realizing that knowing the truth didn't make the castle any safer. It just meant we knew exactly what the ending would look like when it finally arrived.
