Dragons: Riders of Berk Following the events of How To Train Your Dragon, the Vikings of Berk and their former enemies, the dragons, are living together in peace, but this co-existence is not as harmonious as one may think. The dragons, being the wild beasts they yet remain, unintentionally stir up trouble time and again, leading to the more grouchy types among the Vikings to take exception to their presence. And on every such occasion, it falls upon Hiccup and his friends to work on a solution for the problems.
