After the defeat of Drago Bludvist the young heroes think they are safe, but shortly after their victory Berk gets attacked by Screaming Deaths. The dragon riders have to find out what is going on before the unknown enemy is able to unleash an unstoppable storm. This story happens after the second film. There are not a lot of fanfics that stay completely faithful to the source material, but don't we all want a classic HTTYD story? A new story in the same universe and timeline, with the same characters, and no crazy additions. Enjoy.
