No dragon is safe... Hiccup and the riders find themselves captive to Viggo Grimborn after an incident involving the dragon eye and a wild titan. They are taken to Ragul; a place no rider would ever want to step foot, a place that is a true nightmare, an island dedicated to killing the very creatures the riders are fighting to protect. Unable to escape, the riders are forced to face whatever is thrown their way and face some new unexpected foes- There are more than two Grimborns.
