Alternateuniverse (3,936 alternateuniverse stories)

An alternative universe (AU, also known as an alternate universe, alternative timeline, alternate timeline, alternative reality, or alternate reality) is the occurrence of canonical facts about the setting or characterization of a particular fictional universe being explored in a non-canonical way. These universes are often made unofficially, though elements of fan fiction are sometimes used in official, though usually non-canonical, storylines.

Stories that fall into this definition are usually "what-ifs", where possibilities arising from circumstances that do not occur in the original fictional universe are explored. For example, the premise of an alternative universe story may go something like this: "What would happen if character X was killed before event Y could happen?" Unlike regular fan fiction, which generally remains within the boundaries of the canon set out by the author, alternative universe fiction writers like to explore the possibilities of pivotal changes made to characters' history, motivations, or environment.

It was the romance that ended the animosity between two kingdoms from centuries of bad blood. All across the land, be it nobility, gentries, and even the commoners, witnessed the marriage between the star-crossed lovers––the Queen of Izland and the Princess of Oneiric kingdom. And their infamous union continued to be retold generations later.  But what is unknown to most is that the story has always been much more complicated than it seemed.
