The Star Hub and Spice Code for Two
"This gear is stuck too tight!" Hailey lay across the workbench, her nose almost touching the vibranium ring. Moonlight slanted through the attic skylight, silvering her eyelashes. Her father wore welding goggles and held a magical crystal in his tweezers, blue light from the weld flickering across his lenses. "Did you memorize Metals and Magical Conductivity like I asked last time? On page three, where it talks about vibranium alloys..."
"I remember!" Hailey's hand, welding torch raised, hung in midair as she caught the sweet scent of caramel pudding wafting up from downstairs. Her mother was baking her favorite rum-flavored kind. Ever since work had begun on the Star Hub Necklace, Mr. and Mrs. Leicester had taken turns keeping watch in the attic, calling it "family craft time" when they were really there to stop her from melting her wand into the gears.
"Secure the Star Orbit Array first, then set the crystal." Her father tapped the back of her hand with his tweezers. "Just like sewing a button on your teddy bear. Line up the patterns." Hailey stuck out her tongue, suddenly remembering the embarrassing time when she was nine and had sewn Nini's wool sock into a magic pouch. She had stuffed three lemon drops inside, and the pouch had turned into a popping candy bomb so sour it made your eyes water.
When the first gear clicked softly into place, a shadow suddenly swept past the window. It was Eileen's owl, with a little paper packet wrapped in bay leaves tied to its leg. Hailey hurriedly pulled off her goggles and nearly dropped the welding torch into the cauldron. "It must be the Ceylon cinnamon she just got her hands on!" A crookedly written note fell out of the packet: Hailey! I stole Dad's Persian saffron. Want to try the spice thread tomorrow? Beside the signature was a drawing of a butterfly being poked with a wand, with an unidentified liquid dripping from its wings.
"Eileen's after the Potions cabinet again." Her father shook his head with a smile and rummaged through the toolbox for some waterproof magic wax. "Her mother said all the nutmeg in the kitchen turned into glowing balls last week. The House-elf thought she'd wandered into a ghost cave." Hailey imagined Eileen tiptoeing up to steal the spices and couldn't help laughing, but just then, she accidentally let the magical crystal roll into a crack in the floor.
"Merlin's beard!" She lay down and felt around the floor, and her fingertips suddenly touched a cold piece of metal. It was a page from her father's old experiment notes, bearing a few lines in his untidy handwriting: When magic becomes a measurable wavelength, the boundary between Muggles and wizards is merely resonance at different frequencies. Hailey's heart skipped a beat. She remembered the fragment of a Prophecy book she had dreamed of the night before; its twisted writing seemed to bloom into gear-shaped flowers beside those words.
At noon the next day, Eileen shot into the Leicesters' garden like a cannonball, two or three rose petals caught in her blond hair and a bulging silk bundle in her hands. "Look! I stole Dad's mithril scales, and..." She lifted a corner of the bundle with an air of mystery, revealing half a turmeric root wrapped in gold leaf. "Potions-grade turmeric from Indonesia! Smell it-it's three times as strong as the stuff from a Muggle supermarket!"
Hailey quickly ushered her under the rose trellis and sat her down. When Nini came over with a silver tray, Eileen greeted her at once with a sweet smile. "Good morning, Nini! Your bow looks so pretty today!" The House-elf's walnut-shaped face flushed bright red, and she nearly knocked over the crystal pitcher of iced lemonade as she turned around-clearly, she was still bothered by the time she had choked on lemon juice three years ago.
"Let's test the spice thread first." Hailey spread things out on the workbench, where twelve different colors of silk thread lay arranged. "The one we made with gum arabic last time was too sticky. When I pulled it apart, it nearly tore my sleeve off." Eileen nodded and pulled a small bottle engraved with vines from her bag. "How about agave nectar? I read in Potions Basics that a Sticking Charm can produce a wonderful reaction with plant sugars."
The moment the agave nectar dripped onto the silk thread, the whole length suddenly glowed fluorescent green, like a magic snake brought to life. Hailey was quick enough to tap it with her wand and cast a Freezing Charm before it could wrap itself around Eileen's butterfly hair clip. "Merlin above!" Eileen exclaimed. "If you used that to tie up a cauldron, I bet even a Blasting Curse couldn't blow it open!"
"But the color's too conspicuous." Hailey frowned and pinched the thread between her fingertips. "If we pull out a fluorescent green clasp in Defense Against the Dark Arts, Snape could snap our wands into matchsticks." Eileen's eyes suddenly lit up, and she rummaged through her bag for a little amethyst bottle. "Try this! I mixed a bit of a Colour-Fading Charm into blueberry juice. Yesterday, I turned my brother's toad sky blue."
The mixed thread turned a soft smoky gray. Hailey stuck a length of it to her father's old pocket-watch chain and gave it a gentle tug. The thread didn't budge, but it fell off on its own when she touched it with magic. "Perfect!" She and Eileen high-fived, only to accidentally knock over the bowl of magical crystals. Thirty crystals rolled all over the floor, glowing pale green in the sunlight like fireflies caught in a Full Body-Bind Curse.
"We need a name for the clasp." Eileen chewed on the shaft of her quill and drew more than a dozen gear designs on a piece of parchment. "How about 'Magic Quick-Access Clasp'? Too tacky. 'Star Orbit Mithril Pendant'? Sounds like a suit of medieval armor." Hailey looked at the sundial outside the window, where sunlight was casting a fan-shaped shadow from its gnomon onto the grass, and suddenly remembered the "resonant frequency" in her father's notes. "How about 'Star Hub'? A hub for stars, and it has the sense of a gear, too."
Eileen's eyes lit up. "Add 'Energy Conversion'! Star Nexus Energy Conversion Necklace—it sounds like glowing magical machinery!" The two were high-fiving in celebration when Mrs. Leicester appeared with a tea tray, her moon-phase pendant swaying gently against her chest. "What magical machinery are you discussing?" Hailey hurriedly covered the crystals with her sleeve, but her mother only smiled and set down a strawberry tart. "Remember to leave a secret compartment in the necklace for sugar cubes. I see you sneaking snacks every time you do crafts."
By the time the last magical crystal was set into a gear, it was late at night. Hailey stood before the mirror, looking at the clasp, now a finished necklace, glowing faintly against her collarbone. Eileen had traced the initials "H.L" along the edge of a gear in gold dust, and tiny turmeric-yellow spots decorated the wings of the butterfly design, made with turmeric powder mixed with a Hardening Charm. "Time to test the waterproofing." Her father handed her a spray bottle. "It's always raining near the Whomping Willow at Hogwarts. I don't want you losing your wand on your first day."
The moment the mist from the spray bottle touched the necklace, Hailey felt a sudden chill against her chest. The magical crystals blazed, and the gears began to turn on their own, flinging the droplets into tiny rainbows. Eileen clapped excitedly. "It's like a miniature magic fountain! Hailey, you're a genius inventor!" But Hailey noticed the pride in her father's eyes behind his lenses. His gaze reminded her of the first time she had successfully levitated a feather, when she was a little over seven; her mother had smiled and stroked her head just like that.
"Now it's time to give the necklace a scent." Eileen took out a carved wooden box containing twelve kinds of dried spices. "I tried basil leaves with rosemary, but that smelled too much like kitchen seasoning. Lavender and mint smelled like a fragrance for pajamas..." She suddenly held up two slices of dried ginger. "Let's try this! You said the ginger tea you drank in Guangdong in your previous life could keep the cold away. If we mix ginger and lemongrass, we'll have a 'cross-dimensional friendship fragrance'!"
Watching how serious she was, Hailey suddenly remembered the times they had roasted marshmallows with their wands in their secret base. Eileen had always burned the marshmallows black, yet insisted that "it's a Potions carbonization reaction," and in the end they had been left sharing the strawberry jam Nini had secretly stashed away. "Lemongrass first, then sprinkle in the ginger powder." She took the wooden spoon and deliberately tapped the back of Eileen's hand with the tip of her wand. "If you turn it into spicy perfume, I'll swap your butterfly hair clip for an onion pendant."
When the fragrance, a mixture of fresh citrus and spice, filled the attic, the Star Hub Necklace suddenly gave a soft hum. The fluorescent butterfly on the gear fluttered its wings as though about to take flight, as if sniffing the spices in the air. Eileen grabbed Hailey's wrist in excitement. "Do you feel it? The magic and the fragrance are resonating! It's like... like a wand and a spell working perfectly together!" Hailey responded just as joyfully and promised to make Eileen an identical necklace in a couple of days. It would be a symbol of their friendship!
Late that night, Hailey lay in bed, touching the Star Hub Necklace around her neck. Outside the window, a flock of owls swept past, bearing moonlight on their backs. A low whistle sounded from somewhere in the distance—the night train in the Muggle world. She recalled her father's words about "frequency resonance" earlier that day and suddenly felt that she was like the necklace, connected to both the star orbits of the wizarding world and the gears of the Muggle world.
"Nini," she whispered into the darkness, "do you think Hogwarts will have a cauldron suitable for making ginger tea?" The House-elf's snores came from inside the wardrobe, accompanied by a faint scent of caramel pudding. Hailey smiled, and as she turned over, she heard the necklace's gears turning softly, like some secret quietly at work.
Perhaps the "sacrifice" in the Prophecy was only an equation, and she was using the gears and spices of the Star Hub Necklace to solve it and find her own answer. After all, in this world where magic and science intertwined, nothing was more reassuring than inventing magical items with her friend and family, then giving them their own special scents. As for what the future held-Hailey touched the crystal necklace, feeling the emerald magic pulsing inside it—she was ready, in any case, to use cross-dimensional wisdom to brew her own warmth and light in the castle of Hogwarts.
