About this season
Set 1,300 years after the events of How to Train Your Dragon, dragons are now just a legend to the modern world. When a geological anomaly opens an immense, miles-deep fissure in the Earth’s surface, scientists from all over the world gather at a new research facility to study the mysterious phenomenon. Soon a group of misfit kids, brought to the site by their parents, uncover the truth about dragons and where they’ve been hiding -- a secret they must keep to themselves to protect what they’ve discovered.
