Dimensional Runes of Hogwarts

When Arthur Cole, a modern scholar obsessed with the occult, accidentally activates the ancient runes of Kamar-Taj, he tears through the dimensional barrier and falls into the world of Harry Potter, but loses the pages of his notebook containing key spells. With only his remaining magical theories and a unique gift of "dimensional affinity," he becomes the most special student at Hogwarts: his wand can cast both Lumos and the golden sparks of Kamar-Taj.

Here, in Ravenclaw's star dome, he reconstructs the truth of magic:

Using runes to analyze the Seraphim Shield, the shield spell that amazed Flitwick;

Using wizard magic to tame dimensional energy, he bound a mutated Acromantula deep in the Forbidden Forest;

The game with Hermione Granger - she could decipher his "Raven's Shadow" handwriting, but she couldn't see through the afterimage of the New York Sanctuary that flashed in the mirror when he gazed into the Mirror of Erised.

When Voldemort obtained the lost forbidden notebook, the twisted power of the dark dimension eroded the wizarding world: Nagini transformed into a multi-eyed snake, the Killing Curse was wrapped in scarlet energy, and spatial cracks seeped out of the walls of Hogwarts...

On the night of the final battle, Arthur stood in the ruins of the Great Hall. The runes carved on his wand were no longer any known runes—the "Seal of Creation," a symbol that blended the essence of magic from two worlds. Hermione's voice pierced the battlefield: "This time, your wisdom must burn for everyone."

——When the dimensional laws of Kamar-Taj collide with the wizard's blood magic, who is the real "heretic"?
