March 13th, 1993, Hogwarts Corridors, 4:15 PM
Luna and Astoria moved through the corridors with purpose, the torn page from Hermione's hand clutched carefully in Luna's fingers. The castle felt different now—darker, more oppressive, as though the very stones knew something terrible was unfolding within their walls.
"Professor Flitwick's office is this way," Astoria said, her usual composure firmly back in place despite the tremor Luna had noticed in her hands. "He'll know what to do. He always does."
They found the tiny professor in his office, surrounded by stacks of parchment and a teacup that looked comically large in his diminutive hands. He looked up as they entered, his expression shifting immediately from mild curiosity to sharp attention.
"Miss Greengrass, Miss Lovegood. You both should be in your common rooms. The Headmistress was quite clear—"
"Professor, we've discovered something important," Astoria interrupted, which was so unlike her that Flitwick's eyebrows rose. "About the monster. About the attacks."
She quickly explained what Luna had found—the parchment in Hermione's grip, the information about basilisks, the theory about pipes and reflected images. Flitwick listened intently, his expression growing graver with each word.
"A basilisk," he breathed. "Of course. The King of Serpents. That would explain the petrifications, the lack of deaths..." He stood abruptly, his chair scraping against the floor. "This information must reach Professor McGonagall immediately. Well done, both of you. Truly exceptional work. Now, you must return to—Miss Lovegood?"
Astoria turned. The space where Luna had been standing was empty.
"Luna?" Astoria's voice pitched higher. She rushed to the doorway, peering out into the corridor. "Luna!"
The hallway stretched in both directions, populated only by moving portraits and the occasional suit of armour. No sign of the blonde Ravenclaw girl.
Panic clawed at Astoria's chest. 'How could she just disappear? We were right here, I was talking to Professor Flitwick for barely two minutes, she was right there—'
"Miss Greengrass, calm yourself," Flitwick said gently, though his own expression was troubled. "Perhaps Miss Lovegood went to inform another professor? You know how she is...rather... unconventional in her methods."
Astoria forced herself to breathe. Yes. That made sense. Luna was always wandering off, always following invisible creatures or pursuing some tangent that made perfect sense to her and confused everyone else. She'd probably spotted a Nargle or a Wrackspurt or some other imaginary thing and decided to chase it whilst simultaneously alerting another teacher.
'She's fine,' Astoria told herself firmly. 'She's just being Luna. Air-headed, distracted Luna who can't stay focused for more than five minutes.'
But the knot in her stomach didn't loosen.
Three Minutes Earlier
Luna had been listening to Astoria explain their findings to Professor Flitwick when movement caught her eye—a flash of red hair disappearing around the corner, moving with unusual purpose.
Ginny Weasley.
Something about the way the younger girl moved made Luna's instincts prickle. It wasn't Ginny's usual timid shuffle. This was purposeful, almost mechanical, like a puppet being pulled by strings only she could see.
Luna knew she should stay with Astoria. She knew they should inform the professors together. But those grey eyes had caught something the others would miss—the way Ginny's hands clutched a black book to her chest, the way her lips moved soundlessly, the way she walked as though in a trance.
Luna's pursed her lip, memory the day of at Flourish and Blotts resurfaced. She and Ethan had witnessed Lucius slipped that book to Ginny, yet her Teacher said nothing and so was she. She knew that Teacher had his reasons, and that would be anything pivotal, an pranks perhaps.
However with, how things had been since since she set foot in Hogwarts up to when Harry's telling what the book was about. Luna couldn't help but connect the dot.
Ginny was the Heir, yet her Teacher, a true seer at that, should had have learning a things or two about that book, the moment he laid eyes on it. 'Why didn't Teach interfere? What was he planning?'
However, Luna decided to throw such problematic questions to the back of her head. 'Now is not the time'.
With that, Luna's feet carried her into the corridor, following the distant figure of Ginny Weasley. The younger girl moved quickly, taking turns that led deeper into the castle, away from the common areas, away from people.
Luna followed at a careful distance, her mind cataloguing oddities: Ginny didn't look around, didn't check for observers, didn't hesitate at corners. She moved with the surety of someone being guided.
Or controlled.
'Harry,' Luna thought. 'I should get Harry. Ron. Someone.' But Ginny was moving faster now, and if Luna lost sight of her, they might never find where the diary was leading her.
The corridors grew colder. Damper. They were descending, Luna realised, heading toward the lower levels of the castle. Toward the dungeons. Toward...
Ginny stopped before a blank stretch of wall. Her lips moved, forming words Luna couldn't hear, and the wall rippled like water, revealing a dark opening that yawned like a mouth.
The Chamber of Secrets.
Luna's breath caught. She should run. She should scream for help. She should do anything except follow Ginny into that darkness.
But Ginny was her friend's sister. Ron's little sister. And something was terribly, horribly wrong with her. Luna couldn't just let her walk into danger alone.
'Stupid,' Luna thought as she stepped through the opening. 'This is exactly how people die in horror stories. The Nargles are definitely going to mock me for this.'
The passage sealed behind her with a sound like grinding stone.
Ahead, Ginny descended into shadow, the diary clutched to her chest like a lifeline. Luna followed, one hand trailing along the damp wall, her wand held loosely in the other.
The tunnel sloped downward, deeper and deeper into the earth beneath Hogwarts. The air grew thick and foul-smelling. Water dripped from somewhere unseen. And still Ginny walked, never slowing, never looking back.
Until suddenly, she stopped.
Luna froze, pressing herself against the wall. They'd reached a vast chamber—a cavern carved from living rock, with enormous stone serpents coiling up pillars that vanished into darkness above. The space felt ancient, malevolent, as though hatred had seeped into the very stones over centuries.
Ginny stood in the centre of the chamber, swaying slightly. The diary fell from her hands, landing with a soft thud on the stone floor.
Then she collapsed.
Luna started forward instinctively, but something grabbed her ankle—something that felt like icy fingers, like water made solid, like darkness given form. She looked down to see shadows coiling around her legs, pulling her down, and she had just enough time to think 'oh, this was definitely a mistake' before everything went black.
March 13th, 1993, Forbidden Forest, 4:47 PM
The forest had grown darker as Harry, Ron, and Draco followed the endless stream of spiders deeper into the trees. Fang whimpered constantly, pressing close to Harry's legs, and Harry didn't blame him. The forest here felt wrong—too quiet, too still, as though even the trees were holding their breath.
"I hate spiders," Ron muttered for the seventeenth time. "Why did it have to be spiders? Couldn't Hagrid have given us a clue involving, I don't know, rabbits? Nice, fluffy rabbits?"
"Because rabbits don't know anything about ancient monsters," Draco said, though his voice was tighter than usual. Even he looked unsettled by the massive webs beginning to appear between the trees, some spanning gaps wide enough to catch a horse.
The spiders led them to a clearing—if it could be called that. It was more of a hollow in the earth, surrounded by trees so massive and ancient they seemed to predate the castle itself. And everywhere, covering every surface, were spiders.
Hundreds of them. Thousands, perhaps. Bodies ranging from the size of dinner plates to the size of small dogs, all clicking and chittering in a chorus that made Harry's skin crawl.
"Hagrid," Harry called out, his voice steadier than he felt thanks to Ethan's Cogitation training. "We're looking for information about—"
Movement exploded around them. Spiders dropped from above, surged from below, moving with terrible coordination. Harry felt something like rope—no, silk, sticky spider silk—wrap around his arms, his legs. He heard Ron shout, heard Fang's terrified bark cut off abruptly.
The world tilted as he was lifted, carried by dozens of hairy legs toward the centre of the clearing. Through the chaos, Harry caught a glimpse of Draco diving sideways, his position near the edge of the group allowing him to dodge the initial capture. The blonde boy disappeared into the shadows between the trees.
'Good,' Harry thought as the spiders deposited him roughly on the ground beside Ron and a whimpering Fang, all three of them wrapped so thoroughly in silk they could barely move. 'At least one of us is free.'
The clicking grew louder, more excited, and then something massive moved in the darkness at the clearing's edge.
The spider that emerged was the size of a small elephant. Its body was grey and covered in thick, coarse hair. Eight legs, each thick as a young tree trunk, carried it forward with surprising delicacy. But most horrifying were its eyes—eight milky-white orbs that saw nothing, yet seemed to stare directly into Harry's soul.
"Aragog," Harry breathed, remembering Hagrid's stories about his "misunderstood" pet acromantula.
"Hagrid?" The spider's voice was a dry whisper, like wind through dead leaves. "Hagrid does not come to the forest anymore. Has he sent men to me?"
"He's in t-trouble," Harry said, fighting to keep his voice level. The Cogitation exercises helped, pulling his mind into focus even as primal fear screamed at him to panic. "The Chamber of S-secrets has been opened again. T-they've arrested Hagrid."
A ripple went through the assembled spiders—a wave of clicking that might have been distress or anticipation or hunger. Harry couldn't tell.
"The Chamber," Aragog said slowly. "Many years ago, they blamed Hagrid for its opening. Blamed me for being the monster within. We were both innocent."
"Then t-tell us what the real m-monster is," Harry pleaded. "Help us p-prove Hagrid's i-innocence."
"I was brought to Hagrid as an egg from a distant land," Aragog said, his blind eyes seeming to stare past Harry at memories long faded. "Hagrid was just a boy, but he cared for me, hid me in the castle. When the Chamber was opened, a girl died. They blamed Hagrid for keeping me. But the creature that truly lives in the Chamber..." The ancient spider's voice dropped to a whisper. "That creature is an ancient enemy of my kind. We spiders fear it above all others. I will not speak its name."
"A basilisk..." Harry said. It wasn't a question. The year involving Jasper and Osian, the year Harry began some preparation for the Wizarding World under Ethan had paid off.
Aragog's legs shifted, a movement that spoke of deep unease. "If you know its name, then you know its nature. Hagrid is innocent of unleashing it. He would never willingly harm students."
"Then let us go," Ron said desperately. "Let us go so we can prove it!"
"I cannot deny my sons and daughters their food when it comes to us so willingly," Aragog said, and there was genuine regret in his voice. "Goodbye, friends of Hagrid."
The old spider turned, retreating into his nest of shadows. The smaller spiders surged forward, clicking eagerly, mandibles working.
Harry's mind raced. They were going to die here, eaten by giant spiders in a forest clearing whilst Hermione lay petrified and whoever controlled the basilisk continued their attacks. He couldn't die. Not here. Not now. Not when Luna might be in danger, not when—
"INCENDIO!"
Fire blossomed at the clearing's edge—not the controlled flames of a proper spell, but a wild, roaring explosion that sent spiders scattering. Then smoke, thick and acrid, billowing across the hollow in choking clouds.
Through the chaos, Draco appeared, his wand smoking, his face set in grim determination. "Failed potion from last month," he gasped, tossing what looked like several more vials into the mass of spiders. "Seemed like a good time to test them."
The vials shattered, releasing more of the thick, choking smoke. Spiders clicked in confusion and rage, moving erratically.
"Arania Exumai!" Draco's wand slashed through the air, and the curse struck the spiders binding Harry. The silk dissolved, leaving him free to scramble upright.
Immediately, Harry's hands fumbled for his satchel, finding the silvery fabric. He threw it over Ron and Fang whilst Draco cast the spider-repelling curse again, buying them precious seconds.
"Fang, find the way out!" Harry commanded.
The boarhound, nose superior even in terror, bolted toward the trees. The three boys followed, stumbling through smoke and darkness, spiders clicking furiously behind them. Draco threw his last failed potion over his shoulder—this one exploded with a sound like a thunderclap, buying them a few more precious seconds.
They ran.
Trees whipped past. Roots tried to trip them. Spider silk caught at their robes. But Fang led them true, following the scent-trail back toward Hagrid's hut, toward safety.
They burst from the forest's edge as the last light faded from the sky, gasping and covered in web-silk and soot. Behind them, the clicking faded into the distance.
"Never," Ron panted, "again. Never. Again."
Draco collapsed against a tree, his expensive robes ruined. "Failed potions," he muttered. "Who knew they'd actually be useful?"
Harry wanted to laugh, wanted to cry, wanted to scream at the absurdity of being rescued by botched homework. But then he saw the figures approaching from the castle—Astoria Greengrass, running toward them with Professor Flitwick struggling to keep pace.
One look at Astoria's face told Harry something was terribly wrong.
March 13th, 1993, Hogwarts Grounds, 5:34 PM
"Luna's missing," Astoria gasped out, her cool facade completely shattered, she began retelling the whole thing from what Luna discovered up to the point when they decided to tell other professors. "Ginny too. We've been searching but they're gone, they just disappeared, I only looked away for a moment—"
The world seemed to tilt beneath Harry's feet.
Missing. Luna was missing.
Something cold and terrible unfurled in Harry's chest—not panic, though panic was there, screaming at the edges of his mind. Not fear, though fear gripped his heart like a vice. This was something darker, something primal and vicious that he'd never felt before.
Killing intent.
The thought that Luna might be hurt, might be in danger, might be facing the same fate as Hermione or worse—it ignited something in Harry that burned hotter than fire, colder than ice. If anything had happened to her, if anyone had harmed her, Harry would make them pay. He would make them suffer. He would—
'Control,' Ethan's voice whispered in his memory. 'Emotion without discipline is just noise. Use it. Channel it. Don't let it control you.'
The Cogitation training clicked into place like a key in a lock. The killing intent didn't disappear—it burned there, cold and patient—but Harry's mind cleared around it. His thoughts moved like gears shifting seamlessly, each piece of information clicking into place with crystalline precision.
Aragog had mentioned a girl dying the last time the Chamber was opened.
A girl.
Moaning Myrtle.
Myrtle died fifty years ago in a bathroom.
The same bathroom where Harry had found Tom Riddle's diary.
The Chamber's entrance was in that bathroom.
"I know where they are," Harry said, his voice flat and cold enough that even Draco took a step back. Ron and Astoria were staring at him with something like fear in their eyes, but Harry didn't care. All that mattered was Luna. Finding her. Saving her. Making sure she was safe.
"Mr. Potter," Flitwick began, "you cannot possibly think to—"
"Moaning Myrtle's bathroom," Harry interrupted. "That's where the entrance is. That's where the girl died fifty years ago. That's where they'll be."
He started toward the castle at a run. Behind him, he heard Ron and Draco scrambling to follow, heard Astoria explaining rapidly to Flitwick about the Moaning Myrtle part, heard the tiny professor beginning to organise a response.
But Harry couldn't wait. Every second mattered. Every moment Luna was down there alone was a moment too long.
He was halfway across the entrance hall when someone stepped out from behind a pillar—someone with perfectly coiffed hair and robes of turquoise silk, carrying an oversized trunk.
Gilderoy Lockhart, attempting to flee.
"Ah, Potter!" Lockhart said with forced cheerfulness. "Terrible business, this Chamber nonsense. I've just received an urgent summons from the Ministry and I'm afraid I must—"
"Expelliarmus!"
The disarming charm wasn't one Harry had fully mastered—it was supposed to be beyond second-year level. But fuelled by cold fury and desperate need, the spell ripped Lockhart's wand from his hand and sent it clattering across the stone floor.
Lockhart gaped. "I say! That's hardly—"
Harry levelled his own wand at the Defence professor's chest. "Y-you're coming with us. Into the Ch-chamber."
"Now see here, I'm a busy man, I have responsibilities—"
"You're a f-fraud and a coward," Harry said, each word precise and cutting. "But you're also an adult with a w-wand. We might need that. So you're coming. M-move."
"Potter," Draco said quietly from behind him, "we should wait for the other professors—"
"Luna doesn't have t-time." Harry's wand didn't waver. "Mr. Lockhart. Move. N-now."
Something in Harry's voice—that cold, terrible certainty—made Lockhart's protests die in his throat. The man retrieved his wand with shaking hands and allowed himself to be herded toward the stairs.
"I'm going to tell Flitwick and McGonagall where you've gone," Astoria called after them. "Don't do anything stupid!"
"Too late," Ron muttered, but he stayed at Harry's side, his own wand drawn.
Draco hesitated, then turned to Astoria. "Help them organise the professors. We'll delay if we can, but if Harry's right about the location..."
"Go," Astoria said. "Keep them alive until the adults arrive."
The boys ran.
March 13th, 1993, Moaning Myrtle's Bathroom, 5:52 PM
Myrtle was delighted to have visitors, especially since they were asking about her death.
"Oh yes!" she said, her ghostly form bobbing excitedly. "It was right here, in this very stall! I was crying because Olive Hornby had been teasing me about my glasses, and then I heard a boy's voice speaking a strange language, and I opened the door to tell him to go away because it was a girls' bathroom, and then..." She gestured dramatically. "I died! Just like that! All I saw were two great big yellow eyes."
"Where?" Harry demanded. "Where did you s-see the eyes?"
"Over there, by the sinks."
Harry rushed to the indicated sinks, examining each one frantically. There—on the side of one copper tap was a tiny engraving, almost invisible unless you knew to look for it. A snake, carved with such delicate detail that its scales seemed to shimmer.
Harry pressed his forehead against the cool copper, willing his mind to translate, and hissed: "Open."
The tap glowed with brilliant white light and began to spin. The sink moved, sliding sideways to reveal a massive pipe, wide enough to slide down, disappearing into darkness below.
"Good Lord," Lockhart breathed.
"You first," Harry said, gesturing with his wand.
"Me? But surely—"
"Go. N-now."
Lockhart, with the terrified look of a man realising he'd badly miscalculated, climbed into the pipe. Harry heard his scream fade as he slid down into darkness.
Ron met Harry's eyes. "Together?"
"Together."
They jumped.
The pipe was slick and steep, turning and twisting like a monstrous slide. Harry's shoulder scraped against stone, his robes caught on something sharp, and then he was falling, tumbling out of the pipe onto damp ground.
He landed badly, rolling to absorb the impact. Around him, the space was vast and dark, lit only by the faint phosphorescence of what looked like bones scattered across the floor.
Small bones. Child-sized bones.
Ron landed beside him with a grunt. Further ahead, Lockhart was scrambling to his feet, his perfect hair dishevelled, his silk robes filthy.
The man's face twisted from fear to calculation to something desperate. Before Harry could react, Lockhart lunged forward and grabbed Ron's wand from his grip.
"Right then," Lockhart said, backing away quickly. "I think I'll just be taking this basilisk's skin here"—he gestured to what was indeed an enormous shed snake skin nearby—"back up to the castle as proof of my heroic victory. You boys stay here, try not to get eaten, and remember: I'm Gilderoy Lockhart, award-winning author and—"
"Expelliarmus."
Harry's voice was cold. Clinical. The spell hit Lockhart with the force of a battering ram, sending the man flying backward into the tunnel wall. He hit with a sickening crack and slumped to the ground, unconscious.
Harry calmly retrieved Ron's wand and handed it back to his friend.
"Blimey, Harry," Ron breathed. "You didn't have to—"
The ceiling groaned. Cracks spider-webbed across the stone where Lockhart had impacted. Then, with a rumbling crash that seemed to shake the very earth, a section of the tunnel collapsed, tons of rock and debris cascading down between Harry and Ron.
When the dust settled, they were separated by an impenetrable wall of rubble.
"Harry!" Ron's voice was muffled, distant. "Harry, wait! We need to dig through, we need to—"
"Take care of Lockhart," Harry called back. "Get help. I'm going on."
"Harry, don't be stupid! You can't face a basilisk alone!"
But Harry was already moving, running deeper into the tunnel, an orb of light bobbing ahead of him. Luna was down here somewhere. Ginny too. And nothing—not walls of stone, not giant serpents, not ancient Dark wizards—was going to stop him from finding them.
The tunnel opened into a chamber so that the light barely touched the far walls. Enormous stone serpents coiled up pillars that vanished into shadow above. The floor was slick with water and something that looked disturbingly like slime. The air reeked of decay and old magic.
And there, at the far end of the chamber, was a massive door carved with intertwining serpents.
Harry didn't hesitate as he focused on the carved snakes, and hissed in fluent Parseltongue: "Open for the Heir of Slytherin."
The serpents moved, their stone bodies sliding apart with a grinding sound that echoed through the chamber. The door swung open, revealing the true Chamber of Secrets beyond.
Harry stepped through.
The Chamber was even more magnificent and terrible than he'd imagined. Serpents coiled everywhere—carved into walls, wrapped around pillars, their mouths open in silent screams or hisses. Green light filtered down from somewhere high above, giving everything a sickly underwater glow.
And there, lying motionless on the cold stone floor, were two figures.
Luna. Ginny.
Harry's heart stopped. He was running before conscious thought could catch up, dropping to his knees beside Luna's still form. She was pale, so pale, and her chest barely moved with shallow breaths. Beside her, Ginny looked even worse—almost translucent, as though she were fading away.
Relief and terror warred in Harry's chest. They were alive. Unconscious, but alive. Some bruises marked Luna's arms, and Ginny's robes were torn, but they were alive.
Harry reached out to check Luna's pulse, his hands shaking, when he felt it—that same presence he'd felt in his first year, when Quirrell had turned around to reveal Voldemort's face on the back of his head. That cold, malevolent attention that made his scar burn.
Slowly, Harry stood and turned.
A figure stood near the far wall, emerging from shadow. Tall, dark-haired, aristocratically handsome. Tom Riddle, or the memory of him, looking exactly as he had in the diary's vision but somehow more real, more solid.
He was clapping. Slowly. Mockingly.
The sound echoed through the Chamber like the ticking of a clock counting down to something terrible.
"Hello, Harry Potter," Tom Riddle said with a rather creepy smiled. "I've been waiting for you."
