Fanfiction is fiction (Generally stories or poems) written by the fans. It is separated into genres, like alternate universe, angst, poetry, romance, smut, or fantasy, and is either a multi-chapter series or a one-shot. It is usually shared on sites for storywriting or blogs, like Fanfiction.net or Wattpad.
I read a RWBY fanfiction about Qrow and Raven in the Vytal Festival as students... it was great!
