Hogwarts: Sorry, I'm the Calamity!

Loer transmigrates into the Harry Potter world and awakens an absurdly powerful World Editor!

While all other wizards still follow the rules, Loer... chooses to become the rules themselves!

Spells? The Pen of Laws can rewrite the definition of any spell! Dark Magic? My Concept Imbuement can make "Scourgify" scarier than "Avada Kedavra"!

Dumbledore wants to teach him love and justice. Loer responds with a book on "Muggle Philosophy" that leaves the headmaster questioning his life. As he stares at the shattered Mirror of Erised, the White Wizard falls into deep thought.

Voldemort wants to tempt him into darkness. Loer simply treats the Dark Lord as "research material for the study of souls" and remarks that his form of existence is "full of low-level logical flaws."

Fleur: "I will follow you and witness the birth of a new world!"

Hermione: "Knowledge is the most effective weapon, and he... is knowledge itself!"

Years later, after Loer has single-handedly created a new golden age of magic, he simply says:

"I never wanted to rule the world. I just thought... this old version of yours has far too many bugs."
