Chapter 13: Mnemonic Locket Completion
The Hogwarts library was a labyrinth of secrets, its towering shelves casting long shadows that danced across the stone floor in the flickering light of enchanted lanterns. The air was heavy with the musty scent of aged parchment, the faint creak of leather bindings, and a sweet, dusty undertone that clung to Alex Sterling's robes as he hunched over a cluttered table in the Slytherin study corner. His quill scratched softly against a scrap of parchment, the ink glistening wetly under the dim glow. Around him, stacks of obscure tomes—Cognitive Preservation Charms, Runic Matrices for Memory, and a dog-eared copy of Ancient Enchantments—formed a fortress of knowledge, their pages yellowed and curling at the edges. His Slytherin tie hung loose, the knot slightly askew from hours of fidgeting, a mundane ritual to ease the knot of insecurity in his chest. "Hermione's brain is a bloody supercomputer. If I don't finish this locket, she'll bury me in every class."
Alex's fingers traced the blueprint of the Mnemonic Locket, a delicate lattice of runes etched in his mind by the Artificer's Enigma system. The locket was his edge, a tool to amplify his recall and keep his meta-knowledge plausible without screaming "cheat." His rivalry with Hermione wasn't just pride—it was survival. One slip, and her razor-sharp mind would sniff out the system's glow behind his eyes. He chewed his lip, the faint taste of ink lingering from an accidental brush against his quill, and leaned closer to the parchment, the scent of old paper grounding his focus.

He'd spent days poring over Cognitive Preservation Charms, a dense text that smelled faintly of mildew, its pages brittle under his touch. The book described a feedback mechanism to stabilize memory enchantments, preventing mental overload. Alex scribbled a note, adjusting the rune sequence to incorporate a subtle loop that would filter information flow. "Stable, efficient, no brain-fry. Perfect." His hand cramped, a dull ache from hours of writing, but the system hummed approval, its interface glowing faintly in his vision.

The locket's core was a teardrop-shaped moonstone, its pale surface catching the lantern light like a trapped star. Alex had swapped the base metal from silver to a quartz-copper alloy, the materials chosen for their magical resonance. Quartz, with its crystalline clarity, was sympathetic to data storage, holding memories like a Pensieve. Copper, warm and conductive, ensured a steady flow of Aetheric Essence (AE), binding the enchantment without fraying. He sketched the alloy's rune matrix, a spiral of interlocking sigils that pulsed faintly in his mind. The parchment crinkled under his elbow, the sound sharp in the library's hush.
A shadow fell across the table, the air shifting with the crisp scent of new parchment and ink. Hermione Granger stood there, her arms laden with books, her bushy hair haloed by the lantern's glow. Her brown eyes narrowed, flicking to Alex's parchment with a scrutiny that made his stomach lurch. She set her books down with a deliberate thud, the sound echoing like a challenge.
"Still tinkering with your mystery project, Alex?" Her voice was low, laced with suspicion, her fingers tapping the spine of Standard Book of Spells, Grade 1. "Those runes aren't in any first-year text. I saw you with Runes of Resistance yesterday—sixth-year material. Care to explain?"
Alex's heart skipped, but he leaned back, forcing a lazy grin to mask the panic. He slid his elbow over the parchment, the movement casual but deliberate, and tugged his tie straighter, a nervous tic to buy time. "She's too damn sharp. Deflect, now."
"What, Granger, jealous I'm outpacing you?" His tone was teasing, his smirk practiced. "Just designing a self-writing quill. I'm calling it the 'Granger-Solver'—saves me from your endless lectures."
Hermione's eyes rolled, but the suspicion lingered, her lips pursing as she leaned closer, her shadow swallowing half the table. "Very funny. But you're dodging. Perfect Potions scores, knowing exactly how to stop a troll, and now this? You're hiding something, Sterling, and I'm not buying the 'natural talent' act."
Alex's fingers twitched, brushing the cool edge of the moonstone in his pocket. He leaned forward, his voice dropping to a playful drawl. "Maybe I just study when you're busy memorizing Hogwarts: A History. Or maybe, just maybe, I'm giving the world's smartest witch a run for her Galleons. Nervous yet?"
Her jaw tightened, a flush creeping up her cheeks. "Not nervous. Curious. And I will figure out your trick." She spun on her heel, her robes swishing, leaving the scent of her ink-stained fingers lingering in the air.
Alex exhaled, his shoulders sagging as the tension drained. "Close call. She's a bloodhound." The system chimed softly, acknowledging the successful deflection.

The library's silence pressed in, the distant creak of a shelf settling like a warning. Alex packed his notes, the parchment crinkling, and headed to the Slytherin dorms, his mind already on the crafting session. "Time to finish this. No more delays."
The Slytherin dormitory was a cavern of shadows, the green glow of the Black Lake filtering through the thick windows, casting rippling patterns across the stone walls. The air was cold, tinged with the metallic tang of lake water and the faint musk of old leather. Alex sat cross-legged on his bed, the heavy emerald curtains drawn tight, cocooning him in a private world of magic and strain. The moonstone and quartz-copper casing lay before him, their surfaces cool against his palms. His wand rested on his knee, its wood worn smooth from constant use, a grounding anchor as he prepared to weave the locket's enchantment.

Alex closed his eyes, the system's blueprint flaring in his mind—a glowing lattice of runes, each line precise and demanding. Weaving AE was like threading a needle through a storm, every rune requiring perfect focus. He felt the essence drain from his core, a warm, liquid pull that left his chest hollow. The moonstone began to hum, a faint blue glow pulsing from its center, while the copper alloy warmed, its surface shimmering like molten sunlight. His temples throbbed, a dull ache spreading as Cognitive Strain (CS) climbed, the system's warning flashing red.
[Cognitive Strain Increasing: 35%. Warning: Prolonged Weaving May Cause Overload]
"Almost there. Just the stabilization rune." Sweat beaded on his forehead, the air growing heavy with the coppery scent of magic. His hands trembled, the moonstone's glow flickering as he etched the final rune, a complex spiral that locked the enchantment in place. Pain lanced through his skull, sharp and blinding, but he pushed through, his will a taut wire. The glow flared, then faded, the locket now a dull silver with a cloudy quartz heart, its surface cool and inert.

Alex collapsed onto his pillow, the wool scratchy against his cheek, his breath ragged. The headache ebbed slowly, leaving a strained elation in its wake. "It's done. I did it." He fumbled for the locket, slipping it around his neck, the cool metal a comforting weight against his skin. To test it, he whispered a query, his voice barely audible in the dorm's silence.
"Main component of a non-Newtonian flying carpet adhesive?"
The answer snapped into focus, clear as a Pensieve memory: Tamarind Gum, for elastic shear-thickening under stress. The knowledge wasn't just recalled—it was understood, the locket amplifying his mind like a magical lens. He grinned, the ache in his temples forgotten. "This changes everything. Hermione, eat your heart out."
The Charms classroom buzzed with chaotic energy, the air sharp with the ozone tang of misfired spells and the faint burn of scorched feathers. Third-years darted between desks, wands waving as they practiced vanishing spells, their laughter mingling with Professor Flitwick's high-pitched corrections. Alex sat across from Hermione, his locket hidden beneath his robes, its cool weight a secret weapon. He adjusted his cuffs, a nervous tic, as Flitwick perched atop a stack of books, his tiny frame vibrating with enthusiasm.
"Now, class, a theoretical discussion!" Flitwick squeaked, his wand twirling. "Compare the Intent Threshold for a Body-Bind Curse versus a Levitation Charm. Miss Granger, begin."
Hermione straightened, her quill poised, her voice crisp and textbook-perfect. "A Body-Bind Curse requires a high Intent Threshold—directed malice to immobilize the target. A Levitation Charm, however, only needs focused concentration and a willingness to move the object. It's about emotional feedback, Professor."
Her confidence was a blade, sharp and unyielding. Alex felt the locket hum faintly, its magic stirring as he leaned forward, his tone smooth with competitive smugness. "Actually, Professor, I'd argue it's simpler. It's about Aetheric Symmetry. A Body-Bind Curse creates an asymmetrical AE flow, disrupting the target's magical integrity, which demands a high psychological cost. A Levitation Charm maintains symmetry, gently nudging the object's essence. Intent's just the lens, not the mechanism."
The room stilled, the chatter fading to a stunned hush. Flitwick's eyes widened, his wand pausing mid-twirl. "Mr. Sterling, that's… remarkable. That's from Runes of Resistance, a N.E.W.T.-level text. Where did you encounter this?"
Hermione's book slammed shut, the crack echoing like a gunshot. Her face flushed crimson, her eyes blazing. "That's impossible! No first-year could know that! You're cheating, Alex—there's no way you just knew that!"
The accusation hung heavy, the class's eyes darting between them. Alex's pulse raced, but he leaned back, his smile slow and deliberate, a Slytherin mask of charm. "Just a natural talent, Granger. Maybe spend less time memorizing and more time thinking outside the book."
Flitwick raised a hand, his voice sharp but amused. "Ten points to Slytherin for Mr. Sterling's insight, and ten from Gryffindor for that outburst, Miss Granger. Let's keep this civil!"
[CS Increased: 8%. Cognitive Strain: 51%. Warning: High CS Risks System Instability]
Alex's temples throbbed, the locket's recall taxing his mind. Hermione leaned closer as they packed up, her voice a low hiss. "Play your games, Sterling, but I'm watching you. I'll figure out how you're doing this."
She stormed off, her footsteps sharp on the stone floor, leaving Alex with a sinking feeling. "She's too close. I need to be smarter, or she'll crack me open." The locket was a triumph, but Hermione's probe was a ticking bomb, threatening his secrecy as the Stone plot loomed.
