What Does Expanded Universe Mean?
Fandom CultureThe body of licensed tie-in material — novels, comics, games — that extends a franchise beyond its core canon. Star Wars' Expanded Universe, later rebranded 'Legends,' is the defining example and cautionary tale.
Expanded Universe in Practice
Expanded universes occupy a strange shelf between canon and fanfic: officially licensed and often beloved, but perpetually vulnerable to being overwritten by the next film or series. Star Wars made the term famous with decades of EU novels, then made it infamous in 2014 by declaring nearly all of it non-canon 'Legends' to clear room for new films — a decanonization fandom still grieves and fic still happily ignores. The EU concept gives fandom useful vocabulary for tiered canon, since most franchises maintain some hierarchy in which a cartoon, comic, or novelization counts until it doesn't. Fic writers treat expanded universes as an ingredient list, keeping the characters and lore they like regardless of current canonical status.
Example usage
"She's been writing the EU version of the character since before the reboot and sees no reason to stop now."
