Alternate Universe - Time Travel — Tag Meaning
Builds the premise around time displacement — a character thrown into the past or future, timelines rewritten, or travelers meeting people decades out of their own era. Distinct from the plot-device 'Time Travel' tag mainly in scope: here the displacement is the universe's foundation rather than one episode within it.

Time Travel
Moves a character through time by any mechanism canon or author provides — accidents, artifacts, dying and waking up in the past. Fanfic's favorite configuration sends someone back with full knowledge of the future, instantly converting hindsight into a superpower and grief into a to-do list; meeting younger versions of loved ones (or yourself) supplies the emotional voltage.

Time Travel Fix-It
The combination engine of two beloved tags: someone goes back in time specifically to repair canon's tragedies. A character — often the sole survivor of a bad ending — returns to before everything went wrong, armed with foreknowledge and a list of deaths to prevent. Naruto, Harry Potter, and Star Wars fandoms have built whole cathedral traditions out of this structure.

Alternate Universe - Historical
The catch-all for any past-era relocation that doesn't have its own decade or period tag — ancient empires, the Renaissance, frontier towns, revolutionary barricades. Authors range from meticulous researchers footnoting their hairpins to vibes-first storytellers, and the tag itself promises only that the present day has been left behind.

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.
