Alternate Universe - Noir — Tag Meaning
Lights the story in venetian-blind shadows: a world-weary private investigator, a client who's trouble, rain on the office window, and a city rotten from the top down. The genre is as much voice as setting — first-person cynicism, doomed romanticism — and writers relish casting canon's femme fatale energy wherever it fits best.

Alternate Universe - Detective
Hands a character a caseload and a long coat, whether as hard-boiled private eye, brilliant consulting detective, or weary homicide investigator.

Alternate Universe - 1920s
Pours the cast into the Jazz Age: speakeasies, flappers, bootleggers, and glittering parties with something desperate underneath.

Alternate Universe - 1940s
Sets the story amid wartime and its aftermath — ration books, swing dances, factory floors, and letters that take months to arrive. Even outside explicit war plots, the decade's atmosphere of separation and snatched happiness shapes the romance; Captain America fandom alone has kept this tag thriving for years.

Alternate Universe - Dark
Signals a universe deliberately crueler than canon — heroes corrupted, hope rationed, institutions rotten. It functions as both premise and warning label: authors apply it so readers know the moral floor has been lowered, and it frequently travels with archive warnings and 'Dark [Character Name]' tags that deserve attention before reading.
