Harry Potter: Legacy of the Sacred Temple

When a soul from another world crashes into the wizarding realm, he inherits Merlin's fifteen-century-old legacy—a Sacred Temple built to counter the darkest forces. But this transmigrator plays by his own rules. Dumbledore's Horcrux mission? Hard pass. Voldemort's brotherhood offer? Not interested in noseless allies. Instead, Grindelwald becomes his unlikely mentor, teaching forbidden magic that makes even Slytherin's ghost question his life choices. In a world where canon crumbles and ancient powers awaken, one irreverent outsider will rewrite the fate of magic itself.
