Dark — Tag Meaning
A tonal warning that the fic ventures into bleak, disturbing, or morally ugly territory beyond what its fandom usually entertains. It frequently modifies a character ('dark' versions of heroes) or an entire premise, and conscientious authors pair it with specific warnings about what makes it dark.

Dead Dove: Do Not Eat
Named after an Arrested Development gag, this tag means: the warnings are not exaggerating, the dark content is exactly what it says, and the author is exploring it deliberately. It is fandom's strongest 'proceed with full knowledge' label, used on fic whose disturbing elements are the point rather than incidental.

Morally Ambiguous Character
