My Heavenly Money System in the Wizarding World

Reborn into a London orphanage, William Granger knew a secret: he was a 'Muggle' in the legendary Harry Potter world. No magic, no golden finger—just a seven-year-old boy facing an uncertain future in a world of wizards. Until, a golden coin materialized in his dreams. The 'Money of the Heavens' wasn't just a lucky charm; it was an innate spiritual treasure capable of condensing merit, luck, and faith into cosmic currency. Its true power? A 'Trading in the Heavens' function, allowing William to buy anything from any world, even the formidable 'Lord of Mysteries' Beyonder powers! His first purchase: Sequence 9: Apprentice, granting him abilities no wizard could comprehend. Now, as Hogwarts's letter looms, William must navigate a magical world unprepared for a 'Muggle' who can literally purchase divine authority. But what happens when his secretive ascent begins to ripple through the very fabric of the Wizarding World… and his new sister, Hermione, starts showing signs of an equally unnatural talent?
