It has been 27 years since the attack of Drago Bludvist and his dragon army. A whole new set of Dragon Riders, armed with their dragons and ready to defend Berk and the archipelago, must find a new outpost, explore further, and discover exciting new dragons while protecting their home. Unfortunately, a power hungry Hysterian now controls much of what used to be Berk's territory, including the Edge. These new Dragon Riders, trained by Astrid, believe in Berk's right to freedom and will make their opinions known.
