With the dangerous World Serpent Jörmungandr on the loose, Tom and the Dragon Riders must devise a strategy to protect the realms from the formidable dragon. Sledkin, in relentless pursuit of the Gods Realm and the Dragonsite gem, throws a wrench in their plans when she steals Plowhorn from the Riders.
Faced with the biggest challenge they’ve ever encountered, the team must recruit an army of dragons to fend off Jörmungandr and save the Hidden World.[src]
The Dragon Riders enlist the aid of Carla & Hazel and their scientific knowledge to help them prepare for a mission to neutralize Jörmungandr so they can return him to his chamber and seal him back inside.
Tom's overconfidence turns to frustration, then despair, as he struggles to procure the ingredients for Gronckle Iron in hopes of building a trap to stop the World Serpent.
After a major miscalculation by Tom leaves the fate of the realms in jeopardy, Jun and the riders rally behind Tom and Thunder to face off against the World Serpent.
