The forest is burning. Bolas snap through the air, narrowly missing your wings as you weave through the trees. Grimmel’s poisoned darts thud into the bark around you. Your rider leans low against your neck, urging you forward.

Bursting from the smoke, you stumble into a clearing — where a group of dragons already stand, their riders leaping into defensive stances. Stormfly’s spines snap into place. Hookfang growls, flames dancing across his teeth.

Hiccup steps forward cautiously. “Another dragon with a rider? Who are you?”

Before you can answer, a dart whistles past, lodging in the ground at Hiccup’s feet. Grimmel’s voice echoes through the trees: “You can’t protect them, boy. That dragon belongs to me.”
