Canon Era — Tag Meaning
Keeps the story in the source material's own time period and setting — a tag that matters most in fandoms like Merlin or period dramas, where 'canon era' versus 'modern AU' is the fundamental sorting question. It says nothing about plot compliance, only that the swords, castles, or decade remain in place.
What to Expect From "Canon Era" Fics

Canon Compliant
Promises that nothing in the fic contradicts the source material — events slot into gaps, expansions, or aftermath without breaking anything canon established. It's a precision tool for readers who want their fanfic to coexist peacefully with the original story, and authors wear it as a constraint badge: all of this could have happened.

Alternate Universe - Canon Divergence
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.

Alternate Universe - Modern Setting
The go-to tag for transplanting characters from a historical, fantastical, or futuristic canon into the present day. It's a staple in fandoms like Merlin, Les Misérables, and most period dramas, where writers want the characters' personalities and relationships without the swords, corsets, or spaceships.
