Мой мир перевернулся, но кое-как устоял. За разумотрясение спасибо tvtropes.org, в особенности, вот этой статье.
Вот несколько фактов. :В Кстати, а есть ли на фанфиксе возможность предпросмотра сообщения?

• Nowhere are Moony, Wormtail, Padfoot, and Prongs actually referred to as the Marauders. In fact, with regards to the map they made, it's the singular: "Marauder's", not "Marauders'".
Word Of God claims that they referred to themselves as such, but that was after it was widespread fanon. By then it was the easiest way out.

• One very common bit of fanon is that wizards use "Merlin" as a replacement/euphemism for the word "God," leading to expressions like "for Merlin's Sake," "Merlin knows," "honest-to-Merlin" or the big classic, just "Merlin!" While wizards in canon often do mention Merlin, it's always with expressions like "Merlin's beard!" and variations, never just "Merlin." (In fact, wizards in canon do on occasion use "God" as an exclamation or swear; interestingly enough the one to do so most often seems to be Draco Malfoy.)

• The idea that snake Harry set free from the zoo in the first book later became Nagini. This was a popular fan theory before the end of the series. After the series ended, it was sort of forgotten that the theory had never actually been confirmed and it slipped into the realm of fanon. There's even an associated quote attributed to Rowling, but God Never Said That. In fact, it doesn't make any sense anyway, since the snake at the zoo is a Boa Constrictor and Nagini is a venomous snake. Also, the snake at the zoo had a male voice in the film and Nagini is a female.

• Also, Rowling has never said that Grindelwald was Dumbledore's lover. Fandom made the leap from a simple "Dumbledore loved Grindlewald" to "they were shagging like bunnies". Grindelwald was aware of his friend's feelings, and exploited them. Of course, that's still open-ended enough to allow fans to continue their field day.
