Chapter 35
1. The secret gathering at the edge of the Forbidden Forest
As the setting sun bathed the Forbidden Forest in amber, Hailey Leicester crouched beside the roots of a giant sequoia, a Vibranium stopwatch ticking steadily in her palm. Only when the second hand passed the seventh mark did the tip of Harry Potter's Nimbus 2000 broom pierce the mist-four minutes and seventeen seconds later than agreed, enough time for her to complete three magical frequency spectrum scans with her Vibranium analyser. The Leicester family crest engraved on the metal casing gleamed coldly in the twilight. Her father had made it especially for her from Vibranium offcuts, saying it could "measure the heartbeat of time in the magical world." Her fingertips brushed the inscription inside the lid, "Gears never turn blindly," and she remembered the diagram her father had drawn in his letter last week: "When a stopwatch resonates with magic, time becomes the most honest witness."
"Sorry, sorry!" Harry swung off his broom. The tail of the Nimbus 2000 was still vibrating rapidly, and the Vibranium Balance Ring she had welded onto its handle last week shimmered faintly. "Captain Wood insisted I get extra dive practice. He said to use the mirror Golden Snitch from last time as a live target-" His hair was tousled by the wind, and the lightning scar on his forehead glowed faintly red in the sunset, like an unhealed magical burn. Hailey noticed a new patch on his cuff. Its crooked stitches were clearly the result of a hasty repair, and it reminded her of the boy beside the rubbish bins on Privet Drive who had used breadcrumbs to do arithmetic.
"A live target, really?" Eileen Ronier emerged from behind the ferns. Nutmeg powder she had failed to brush off clung to her panda hairpin, and crystals from a splash of Mandrake syrup she had secretly brewed that morning still clung to its edge. "My brother says if you sprinkle version 2.0 of our family's 'headwind spice' during Quidditch practice, a broom will be as steady as if it were nailed to the ground!" She shook an engraved clay jar, and the sweet, spicy scent of agave nectar and nutmeg gathered into an amber cloud in the air, startling three Thestrals preening one another on a branch into flight. At the smell, Hailey suddenly remembered the warmth of her mother making ginger tea in the kitchen, steam and spices filling the entire manor.
Hermione Granger adjusted her hair. The parchment bookmark in her copy of Outline of the History of Magic fluttered noisily in the wind, and the edges of its pages were densely covered with magical frequency spectrum notes in Vibranium ink. "Hailey, are you sure it's safe here? I was looking things up in the library just now and found that Dark Magic ran out of control in the Forbidden Forest in the fourteenth century. The frequency of the magical residue back then was the same as what you detected..." She spoke rapidly, unconsciously twirling the end of her braid, a habit she had when she was nervous. Hailey noticed the dark circles under her eyes; she had clearly stayed up all night researching.
"A 180-hertz dark magic pulse, right?" Hailey interrupted, tracing an arc on the Vibranium analyser's screen. The instrument emitted a faint hum that resonated strangely with the distant rustling of the Whomping Willow. "That was the frequency the instrument showed when Professor Quirrell demonstrated the Banishing Charm in Dark Magic Defence Class the week before last. But did you notice? The faint green light leaking through the gap in his turban while he cast the spell was exactly the same colour as the Ageing Potion Professor Snape ruined in Potions Class, as if he'd boiled ten pounds of spinach down to ink." She remembered how Snape had watched Quirrell then, like a hawk watching its prey, only to look away quickly when a student asked a question.
Ron Weasley suddenly pointed at a distant thicket, strawberry jam he had secretly helped himself to that morning still on the tip of his nose. "Shh! I think something's moving!" All five fell silent at once. Eileen's panda hairpin flashed alarm red, like a sweet under an Engorgement Charm; Hailey's Vibranium bracelet vibrated rapidly, its gears striking her wrist bone painfully as metallic cold crept along her veins towards her heart. Only when a mottled Thestral ran off, swishing its tail, did everyone breathe a sigh of relief. Ron patted his chest theatrically, and his wand slipped from his robe and landed with a soft patter on the fallen leaves. When Hailey bent down to pick it up for him, she found dark green slime on its tip-venom found only deep in the Forbidden Forest.
"Back to the point." Harry crouched and used a twig to draw Quirrell's outline on the fallen leaves. The sound of the twig scraping through the decaying foliage was remarkably like the Dursley family's ancient typewriter. "We all think there's something suspicious about the cloaked figure drinking Unicorn Blood in the Forbidden Forest, but Hailey, you said..." He hesitated, clearly still coming to terms with last night's frightening scene in the forest.
"I think Professor Quirrell is the mastermind." Hailey kept her voice low. Her serious face was reflected in the Vibranium stopwatch in her palm, and the words her father had engraved inside the lid appeared and disappeared. "The week before last, Quirrell came to sit in on Potions Class. When Snape taught the Smell-Masking Charm, he specifically asked Quirrell to demonstrate, and black smoke started pouring out of Quirrell's turban. That's a classic sign of conflicting spells, like putting a mint sweet in hot cocoa, but Snape said it was an 'execution error.' Don't you think that's strange?" She remembered the quick glance Snape had cast towards her seat, a look as sharp as a Vibranium scalpel, which had softened instantly when their eyes met.
2. A magical argument based on cross-dimensional logic
"Oh! I remember now!" Eileen suddenly clapped her hands, spilling a little spice from the clay jar onto her new turmeric-yellow wizard's robe, where it formed a speckled pattern. "My family's Potions handbook says garlic only drives away low-level vampires, but Quirrell deliberately covered himself in garlic paste. Isn't he obviously disguising himself as a 'victim of Dark Magic'? Like when my brother hid frogspawn in the sugar jar to trick Mum, only to be chased by bees for three streets!" She grew more excited as she spoke, and the jewel on her panda hairpin flashed red, just like a sample from the magical fireworks shop in Diagon Alley. Hailey noticed the nutmeg powder on her cuff and remembered the absurd time when, as children, the two of them had used their wands to make milk tea in the Leicester Manor cellar, adding Moonstone Powder instead of starch and turning the whole pot of drink fluorescent green.
Hermione pushed up the glasses she rarely wore and quickly wrote in her notebook, the scratching of her quill against parchment mingling with the sound of a distant stream. "That makes sense! Hailey, do you have any specific data on the spell conflict you mentioned? The magical frequency deviation, for example?" She opened Advanced Charm Theory, which had a Vibranium bookmark tucked inside. Half a dried turmeric petal fell from between the pages; it was the test version of a "magic stabilising charm" Hailey had given her last week. Hailey pulled up the analyser's historical data. The waveform on the screen looked like an angry snake, its scales flashing a dangerous red.
"Three hundred and fifteen hertz against 180 hertz, a deviation of as much as forty-three percent." Hailey enlarged the waveform. "That's like mixing Butterbeer and Dragon Blood and drinking them. It would be strange if they didn't explode. My dad says a frequency difference like that is like using a Muggle spanner on a magical screw: sooner or later, you'll strip the threads." She remembered her father always humming an off-key Muggle folk song as he adjusted Vibranium components in his attic laboratory, saying, "Magic and machinery both need their parts to mesh precisely." Harry's green eyes lit up like fluorescent fungi suddenly glowing deep in the Forbidden Forest. "And on Halloween night, a hole was burned in Snape's robe. He said a Troll did it, but Quirrell also said he was attacked by a Troll at the time-isn't that too much of a coincidence? I remember Aunt Petunia always making all sorts of excuses when she burned the bread, but there were always scorch marks on the oven door handle." He rubbed the patch on his cuff unconsciously, his knuckles turning white from the pressure.
"More than a coincidence!" Hailey opened her leather notebook. Parchment was attached inside with Vibranium tape, and traces of turmeric powder still clung to the edges of the tape. "I compared the date Hagrid received the dragon egg with Quirrell's 'sick leave' records. They matched exactly. Even stranger, while Quirrell was pretending to be ill, Snape took over Dark Magic Defence Class and specifically taught us 'how to recognise signs of unusual magic.' He even drew a diagram of a 'shadow' on the blackboard, and it looked exactly like Quirrell's outfit, right down to the way the folds curved, as if they'd been measured with a ruler!" She remembered how hard Snape had tapped the blackboard with the tip of his wand, shaking the chalk dust into gear shapes, while Ron secretly drew a pig wearing a turban underneath.
Ron suddenly burst out laughing, revealing front teeth stained yellow by jam. "So Snape was pointing out the important bits for us? Like how my mum always 'accidentally' drops the right answers on the floor before an exam, only for my dad to use them to wrap fish!" The emotion-sensing sweet in his pocket suddenly melted, sticking to the fabric in a comical smiley face. Hailey had made it with Muggle boiled sweets and magical pectin, and it could change shape according to fluctuations in cognition. Tiny golden bubbles were still rising along its edges. Hermione shook her head helplessly, though she couldn't stop the corners of her mouth from lifting. "Ron, your comparisons are always so... vivid."
"And there was the Quidditch Match," Hailey said. She took out a Vibranium ruler, began arranging fallen leaves, and then marked the position of the stands. The ruler's markings gleamed silver in the sunset. Her father had made it by combining parts from an old pocket watch with a Muggle ruler, saying, "You need accuracy when measuring magic too." "When the Bludger was chasing Harry, I timed it with my stopwatch: during the twelve seconds Quirrell spent casting a spell at the edge of the pitch, Snape simultaneously 'tripped himself,' blocking Quirrell's view for eleven and a half seconds, just long enough to send the Bludger off course." She drew a timeline, and the shadow of the Vibranium ruler crossed the trail of Harry's broom on the ground, forming a perfect cross. "Look: 'Quirrell casts a spell → Snape falls → the Bludger changes direction.' That millisecond-level overlap was no accident. It was even more precise than my mum timing her soft-boiled eggs."
Hermione's quill flew across the parchment, the splattered drops of ink solidifying into miniature gears in the moonlight. "When Snape took points, he said it was for 'using magical metal in the stands,' but Vibranium is a Ministry of Magic-certified material. He was deliberately using a vague school rule to hint that we should interrupt the spell! Like when my dad says 'it's time to wash the dishes' in Latin, but actually wants to watch the Quidditch final."
3. Cross-dimensional tracking of dark green magic
"So Snape's been like a magical version of a Muggle agent all along?" Ron's question made everyone struggle not to laugh. The emotion-sensing sweet in his pocket turned into a question mark, and fine droplets seeped through its frosted surface, just like the beads of sweat on his forehead when he was nervous.
"More like a double agent." Hailey stood, pointing the Vibranium analyser towards the depths of the Forbidden Forest. The cursor on its screen looked like a restless firefly. "My father once said the most dangerous gears are often hidden in the most conspicuous places. Tonight, we'll go into the Forbidden Forest and use this equipment to find the truth." She shook the metal box in her hand. Inside was a specially made Leicester family Vibranium beacon, its edges engraved with intricate gear patterns. Her grandfather had forged it with the magic of his entire life, saying it could "hear the sound of fate turning." Harry gripped the handle of his Nimbus 2000. The Vibranium Balance Ring on the broom handle resonated with Hailey's bracelet, making a faint ticking sound, just like the old mantel clock striking the hour at the Dursley family's home.
At midnight, the Forbidden Forest was like a sleeping beast. The air was thick with what seemed to be the lingering metallic sweetness of Unicorn Blood, mingled with the faint hum of the Vibranium beacon. Hailey's Vibranium compass spun wildly before its needle finally stopped in front of a clump of glowing Venomous Tentacula. Hailey cut a little off one tip with a knife, and venom from the tip dripped onto the Vibranium watch casing with a hiss. "Right here! This is where Quirrell drank the blood last time." She remembered the dying unicorn's mournful cry, a sound that had pierced her eardrums like a silver needle. Even now, the memory made the hairs on the back of her neck stand on end. Hermione raised the Vibranium spectrometer, and dark green magical ripples immediately appeared on its screen, with tiny serrations along the edges of the waveform. "Look! This frequency is exactly the same as the Ageing Potion in Snape's Potions Class! It's like the dark green yarn my grandmother uses to knit sweaters, with pills in exactly the same places." As she spoke, the spectrometer's backlight revealed the bloodshot whites of her eyes; she had clearly stayed up researching.
Following Eileen's instructions, Ron scattered spice that could resonate with a Patronus over the ground, moving as clumsily as an owl learning to fly. A miracle happened—the powdered spice gathered in the air into a winding ribbon of light, the exact dark green of Snape's robes. Its flowing movement looked remarkably like spinach soup simmering in the Hogwarts Kitchens. "Follow me!" Harry tightened his grip on his wand. The tail of his Nimbus 2000 traced a silvery-blue light through the mist, and the Vibranium Balance Ring on its handle resonated ever more strongly with Hailey's bracelet, reminding her of a Muggle wind chime she had played with as a child, which rang crisply whenever the wind blew.
The five followed the ribbon of light to a giant sequoia. Several fragments of Vibranium lay scattered among its roots. One bore a faint snake-shaped pattern and had bite marks along its edge. "This is... Snape's button!" Ron picked up the piece of metal and examined it in the moonlight. "He really was here!"
Hailey's Vibranium bracelet suddenly hummed. Its gears resonated with the button as the bracelet absorbed Hailey's magic and the magic remaining in the button. In an instant, the bracelet vibrated again. Hailey channelled its power to form a small ball of magic in her palm, then directed the ball into the external lens of the Vibranium magic analyser. At once, a blurry image appeared in the air: a figure resembling Snape was using a wand to destroy a barrier Quirrell had set up. Dark green magic clashed fiercely with the purple-cloaked figure's dark magic, forming a shock wave visible to the naked eye, just like dough striking the board when her mother kneaded it. She saw that the path of Snape's wand was strikingly similar to her father's gestures when he adjusted Vibranium components, every movement precise to the millisecond.
"Is that Professor Snape? So Snape has been secretly trying to stop Quirrell all along?" Harry's voice was full of shock, his green eyes flickering in the image like two dancing flames. "Then why is he so harsh with us? He's noisier than the Dursley family's vacuum cleaner."
Hailey switched off the analyser, and the lingering glow illuminated her determined face. "Because real protection often comes with thorns. Like when my father uses a Muggle multimeter to test a wand core: it looks as though he's damaging it, but he's really looking for the best point of resonance. My mum once said real warmth is like ginger tea. You have to taste the spice before you can feel the sweetness." She remembered how, whenever her mother handed her ginger tea, she would always say deliberately, "Drink it while it's hot, or it'll turn bitter," though there was always honey settled at the bottom.
4. Breaking the deadlock across dimensions as gears mesh
After coming out of the depths of the Forbidden Forest, the five sat down to rest on the grass at its edge, each holding a turmeric scone Eileen had brought. Little gear patterns had been drawn on the scones in Vibranium icing. Hailey's Vibranium analyser showed that the frequency of dark magic in the Forbidden Forest had dropped by seventy percent. The waveform on its screen had smoothed out, like the breathing of a sleeping baby. Hermione put her notebook away. Its Vibranium bookmark gleamed silver in the morning light, with a turmeric-yellow silk cord Hailey had given her tied to its end. "We have to tell Headmaster Dumbledore about this. But how do we prove Snape is protecting us? We can hardly say, 'Because he takes points so gently.'"
"Show him the logical analysis we've put together," Hailey replied seriously as she ate a biscuit. "My father once said every magical puzzle can be solved with Muggle logic. Look-" She touched the tip of her wand to the notebook Hermione was about to put away, indicating that she should open it. Hermione turned to a blank page, and gold-stamped words appeared: "When pure blood activates the Vibranium gears, the chosen deadlock-breaker shall hear the echoes of the twin gears." The words flowed in the sunlight like liquid gold. Harry suddenly stood up, his Nimbus 2000 trembling slightly in his hand as the Vibranium Balance Ring on its tail resonated with Hailey's bracelet. "I understand! Snape is the 'twin gear.' He resonates with Quirrell in a seemingly hostile way, and his ultimate goal is to protect the Philosopher's Stone! Like when I used breadcrumbs to lay out arithmetic problems on Privet Drive. It looked like I was playing a game, but I was really memorising the multiplication tables."
"Like my family's spice scales." Eileen shook the empty clay jar, and the nutmeg powder remaining at the bottom glittered in the sunlight. "On the surface, they weigh medicinal ingredients, but every division conceals a different magical frequency. My dad calls it a 'trade secret.'" Hailey smiled, her dimples appearing and disappearing in the morning light, remembering how her mother always said that when she smiled, she looked like a little spoon holding sunshine. "What we need to do now is use this Vibranium equipment to find where the Philosopher's Stone is really hidden." She unfolded a map of Hogwarts drawn in Vibranium ink. Gear-shaped marks flashed at key locations. She had stayed up late drawing them with Vibranium powder her father had sent her, leaving her wrist aching for three whole days.
"The underground chamber!" all five said in unison. The hum of the Vibranium equipment formed a strange harmony with the morning birdsong, much like pots and pans clattering as Mother made breakfast in the kitchen. Hailey remembered the final sentence in her father's letter: "When all the gears begin to resonate, even prophecy will make way for you." She looked down at the Vibranium bracelet on her wrist. Its gears were still slightly warm, residual heat from resonating with Snape's button.
5. An unspoken mission and a cross-dimensional alliance
On the way back to the castle, Hailey's Vibranium bracelet suddenly began ticking in a regular pattern. It was a safety signal from her father in Morse code, three short beats and one long one, the same rhythm he had tapped on her headboard at bedtime when she was little. She looked up at the Astronomy Tower, where Dumbledore stood on the balcony, his silver beard billowing in the morning breeze and a lemon sweet in his hand refracting rainbow light in the sun. Ron suddenly stopped. The emotion-sensing sweet in his pocket had taken the shape of a handshake, and strawberry jam from his breakfast still clung to its surface. "Don't you think we've gone from being spectators in the magical world to being the ones breaking the deadlock? Like the first time I won a Quidditch Match, I felt like I could fly."
"Because we've learned to look at problems in different ways." Hermione pushed up her glasses. The Vibranium notebook shone in the crook of her arm, and the little gear she had drawn in ink on its cover had worn somewhat blurry. "Just like Hailey said, magic isn't black and white. It's countless gears meshing precisely, and without any one of them, it can't turn." Harry tightened his grip on the Vibranium compass Hailey had handed him. The chill of the metal came through his fingertips, just like moonlight on a winter night on Privet Drive. "Thank you, Hailey. If you hadn't used these Muggle things..."
"They're not Muggle things. They're cross-dimensional tools." Hailey corrected him and handed Hermione the analyser housed in the Vibranium stopwatch casing. The fluorescent light inside reflected her confident smile, and the words her father had engraved inside the lid appeared and disappeared in the shadows. "Remember, when you hear gears ticking, it isn't a warning of danger. It's the prelude to breaking the deadlock, like when my mum makes ginger tea and the kettle starts bubbling: it means it'll soon be ready to drink." Eileen suddenly pointed at the sky, her panda hairpin turning bright green with excitement. "Look! Those owls are flying in formation!"
Everyone looked up to see four or five owls circling in the shape of a Vibranium gear, their silvery-blue feathers glittering in the sunlight like a moving magical painting. A Leicester family Vibranium message tube was tied to the lead owl's leg, and the family crest engraved on its surface turned gently in the wind. "That's a Leicester family signal," Hailey said softly. Her Vibranium bracelet resonated with the gear in the sky, producing a pleasant hum identical to the sound of Vibranium components wearing into place that she had heard in her father's laboratory as a child. "It should be Father. He may have noticed or discovered something. So, you see, it's as if they're telling us that a cross-dimensional alliance has formed, whether on this side or the other. Now, the next gears are ours to mesh."
As the five entered the castle gates and parted to return to their dormitories, Hailey and Eileen happened to encounter Snape coming towards them from the other end of the corridor. His black robes cast a long shadow across the stone floor, like a streak of solidified ink. When he saw the Vibranium bracelet on Hailey's wrist, his step faltered almost imperceptibly. A trace of complicated emotion Hailey had never seen before flashed through his usually mocking eyes, as quickly as a Vibranium gear turning through an instant. "Miss Leicester, Miss Roniel." His voice was as cold as ever, like well water deep in the Forbidden Forest. "Ten points from Hufflepuff for using magical metal items in the Forbidden Forest."
Hailey and Eileen exchanged a glance. Though they didn't know how he had found out they had gone into the Forbidden Forest, they both smiled in silent understanding. Eileen's panda hairpin trembled gently, scattering a few tiny specks of nutmeg powder. "Yes, Professor." Hailey bowed her head, and the Vibranium stopwatch ticked faintly inside her cuff. She had secretly adjusted it to the rhythm of her father's favourite Muggle folk song. "We'll be sure to take care next time. We promise to be even more precise than the Ageing Potion you brewed."
Snape gave a cold snort, swept his black robes around him, and turned to disappear at the end of the corridor. Hailey watched him go and suddenly remembered something her father had said: "The most silent gears often bear the heaviest load as they mesh." She gripped the Vibranium bracelet on her wrist. Its gears resonated with her heartbeat, sounding the prelude of a cross-dimensional deadlock-breaker between the ancient stone walls of Hogwarts.
