Diagon Alley pulsed with raw, arcane energy.
To most first-year students, the winding street with its crooked shops and flickering wand-lights was a wonder. But to Harry, it was a map of living code—an overlay of circuits and systems only he could see, thanks to his ever-active Mana Lens spell. Leylines snaked beneath the cobbled roads. Floating glyphs shimmered atop archways. Buildings weren't just structures—they were enchanted nodes, some old as the Founders, others glitched with fragmented energy.
And Diagon Alley was lagging.
Harry noticed it the moment he passed the apothecary: a flicker in his peripheral HUD, a hiccup in mana stability. Something was wrong in this magical district's core logic. But he wasn't here to debug it. Not yet.
He had one mission today—get a wand.
The usual shops zipped past him: robes from Madam Malkin's, books from Flourish and Blotts, a boring pewter cauldron. He used the inventory interface to store everything. A click, a pulse, and even his shopping list vanished into his digital pocket dimension.
But as he approached Ollivanders, his mana pool shuddered.
Waves of old, ancient magic pulsed from the crooked little wand shop like soundless bells. Harry's lenses lit up with crimson warning edges.

He pushed the door open.
It was cool and dark inside. Boxes towered up to the ceiling in precarious stacks. Dust motes floated in shafts of light. But Harry wasn't looking at the shelves.
He was scanning the man behind the counter.
Ollivander turned, silver eyes locked onto his.
"Ah," he murmured. "Mr. Potter. I wondered when you'd arrive."

Harry's HUD struggled to read the wandmaker. It was like trying to scan bedrock.
Ollivander didn't wait. "Step forward, boy. Let's find your wand."
The measuring tape wrapped itself around Harry's limbs, reading his every detail. He caught the underlying spells—old code, clunky but functional. Harry could probably optimize it, if he wanted to.
Wands began flying from the shelves.
The first wand—Beechwood and dragon heartstring—exploded in sparks.
The second fizzled like a glitched firework.
The third—the famous one—fit like a redstone torch to a repeater.
Holly and phoenix feather. Eleven inches. Supple.
Magic surged through Harry's veins. The lights brightened. Air shimmered.
[Item: Wand (Phoenix Core)]
[Binding: Partial – Compatibility: 57%]
[Error: Core Conflict with Player Interface]
[Suggested Action: Rebuild Using Mod Framework]
Harry's lips thinned.
"It doesn't fit," he said flatly. "Too many legacy bindings."
Ollivander froze. "You understand wand logic?"
"I understand systems. This one's running on outdated code."
The old man gave him a look that was somewhere between offended and intrigued. "Explain."
Harry opened his hand.
A flicker of his spellbook appeared—transparent but full of raw, modular glyphs. The Ars Nouveau interface opened in the air. Ollivander gasped.
"You're… you're weaving custom spell architecture."
"I need a wand that channels my own code. Not just traditional magic."
For a moment, the shop was deathly silent. Then the wandmaker turned and beckoned.
"Come with me."
He led Harry down a spiral staircase hidden behind a false shelf. At the bottom lay a sub-basement workshop—nothing like the pristine shop above. This was cluttered, filled with vials, crystals, metals, runes etched on every surface. A messy coder's dream.
"This is where I build experimental wands," Ollivander said. "Wands the Ministry has forbidden. Hybrids."
Harry walked past staves made of obsidian and glowing crystals, a half-finished wand wrapped in spider silk, and something that looked suspiciously like a command block fragment fused to a unicorn horn.
Ollivander watched him. "You'll need to design your wand."
Harry pulled up his crafting interface and began mentally assembling components.
Handle: Dark Oak – resistant to overload
Conduit: Silver-threaded Sourcewood
Core 1: Phoenix Feather – legacy compatibility
Core 2: Source Gem + Glyph of Focus – for mana integration
Binding Agent: Enchanted Thread + Stabilized Quartz Dust
He fused them in his mind, each step glowing with precision.
[Crafting: Twin-Core Wand]
[Compatibility: 98%] [Mana Sync: Enabled]
[Spell Protocol: Custom/ArsNouveau v3.1.4]
When he grasped the wand, it responded like a neural link.
The shop shuddered with magical pressure. A ripple of leyline energy pulsed out from the workshop, causing lanterns to flicker.
Harry pointed the wand at a nearby candle and silently thought: Ignite.
Blue fire flared.
No incantation. No flourish. Just thought.
"By Merlin…" Ollivander whispered. "You've rewritten wand functionality."
Harry didn't respond. A new icon had appeared in his HUD:
[Perk Unlocked: Spellweaver]
Wands now function as dual-channel conduits. +20% casting efficiency. Can store and execute code-sequence spells.
As they returned upstairs, Harry paused by the shop door.
"There's a broken toy shop four doors down," he said. "It's not really broken. Just unstable."
Ollivander's eyes narrowed.
"You saw that?"
Harry nodded. "It's not a shop, is it?"
"No," the old man said slowly. "It's a modder's gate. Long abandoned."
Harry smiled faintly. "Not for long."
Outside, the alley buzzed with magic, but Harry no longer walked like a boy. His wand hung comfortably in his hand, humming with power.
His next objective awaited.
The magical world had rules. But rules could be rewritten.
And Harry Potter—Herobrine's heir—was ready to start patching the code.
