What Does Hogwarts AU Mean?
Fic TypeA fusion AU placing another fandom's characters in the Hogwarts setting — sorted into houses, attending classes, playing Quidditch. One of fandom's standard borrowed-world templates.
Hogwarts AU in Practice
The Hogwarts AU became shared infrastructure the way only a generation-defining canon's setting could: the house system offers an instant personality framework (fandom arguments over which house a character belongs to are a genre of their own), the school calendar supplies structure, and the magic curriculum furnishes endless scene material. As a fusion template it ranks alongside daemon AUs and soulmate worlds — settings so widely borrowed they detached from their origin and function as common fandom property. Writers range from full immersion, with wand lore and house politics, to light cosplay where the castle is set dressing for a school romance. The template's usage has also become entangled with fandom's complicated relationship to the source's author, with some writers reframing or explicitly distancing their use of the setting — a live example of fandom renegotiating its inheritance.
Example usage
"The Hogwarts AU sorts the heist crew into all four houses and builds the entire third act around a rigged Quidditch final."
