Alternate Universe - Canon Divergence — Tag Meaning
One of the most-used tags on the entire Archive, marking stories that follow canon faithfully until a single chosen moment and then branch off. Authors frequently specify the divergence point in their summary or in a freeform like 'Canon Divergence - Post-Season 2', which distinguishes this tag from full-rewrite AUs that discard the original setting.
What to Expect From "Alternate Universe - Canon Divergence" Fics

Alternate Universe - Everyone Lives/Nobody Dies
The Archive's great mercy tag: a universe where canon's body count simply doesn't happen. Authors use it both for sweeping rewrites where tragedy is averted and for cozy ensemble fics that quietly ignore every death the source material ever inflicted.

Alternate Timelines
Handles branched chronology explicitly: timelines split by time travel, choices, or cosmic accident, often with characters aware of — or haunted by — the other branch. Where canon-divergence fics simply write one new path, this tag tends to keep multiple paths in play, letting survivors of one timeline carry its weight into another.

Post-Canon
Sets the fic after the source material ends, answering fandom's eternal 'and then what?' Whether it's healing after the final battle, relationships canon teased but never delivered, or simply ordinary life resuming, post-canon is where fandom writes the epilogues it wanted — or repairs the ones it got.
