Fics like A Union of Blood and Fire

Berk and the Dragon Hunters are locked in a war Berk cannot hope to sustain. When a fall leaves Hiccup vulnerable, Viggo Grimborn sees an opportunity: not only to win, but to claim something he never should have wanted. A union born not of peace, but of desperation… and of a desire neither of them dares to name. War made them enemies, and desire could turn them into something far more dangerous.
