Like something out of a campfire ghost story, the Flightmare doesn’t even seem like a real dragon.
Emitting a banshee wail and glowing like a phantasm, the Flightmare has haunted Berkians for generations. The Flightmare’s glow comes from its primary food supply, a unique type of algae that flows through the woods around Berk. This algae glows with bioluminescence in the light of Aurvandil’s Fire, a Northern Lights display that occurs every few years over Berk. When the Flightmare eats the algae, it also glows, giving it an unnatural appearance. The Flightmare’s abilities are almost entirely defensive, so it can be overpowered when cornered or outnumbered by tougher dragons. Because of this, it has become a very territorial and short-tempered dragon, and incredibly protective of its algae food supply.

Flightmares emit a toxic mist that can temporarily paralyze a human. This has led to the legend of Flightmares “scaring Vikings stiff.” While it wears off after a few minutes, the potent mist immobilizes the Flightmare’s target long enough for it to strike.
