Epistolary — Tag Meaning
A canonical tag for stories told through documents: letters, diaries, reports, emails, or their in-universe equivalents. The form is old as the novel itself, and fanfic keeps it thriving with everything from wartime correspondence to starship logs.
What to Expect From "Epistolary" Fics
