A canon divergence AU is a term used in some fandoms for fanfiction set in a universe that diverges relatively narrowly from canon, with a point of departure in a character's backstory or even during canon. The changes made to canon usually answer a question like "What if character X lived instead of died?" or "What if character Y didn't meet character Z until later?" In Discworld, this is known as ending up in "the wrong trouser of time."
Not to be confused with fanfic that accidentally diverges from canon due to being jossed.
Fan writers might change any event in canon to produce a wild variety of AUs, but for any given fandom, certain events make a lot of fans want to write an AU:
- Horatio Hornblower: Live Kennedy Universe
- X-Men First Class: No Beach Divorce
- Harry Potter: Epilogue? What Epilogue?
- The Hobbit: a whole list of Hobbit AUs
