TV Tropes: “Word of Dante”

tv-tropes“Word Of Dante is stuff the creators haven’t said is true about their universe — but everyone assumes it is true because an independent authority, scholar of the work, or Big Name Fan has said it — often with supporting arguments. It’s a kind of ascended Fanon. A more literary criticism friendly technical term for it would be deuterocanon.” [. . .]    —TV Tropes
