The wizard Astrid is planning to cast the False Life spell which will bring to life the bones of giant ancient beasts and allow her to conquer all the kingdoms; in order to prevent her the Dragon Masters must find the Wind Dragon, the final dragon needed to undo the spell--but that dragon and her Dragon Master are captives, and it is up to Drake and his friends to rescue them, and hope they are in time to stop Astrid.

The Dragon Masters are still reeling from the desertion of Rori and her fire dragon Vulcan, when Mina, a Dragon Master from the far north, arrives with a problem--King Lars needs a fire dragon to defeat the Ice Giant who has frozen his kingdom; and so the Dragon Masters set out to find Rori and convince her to help.

Not all of the wizards who were freed from Maldred's time-trap were good wizards; one of them, Astrid, is planning on working a spell that will bring to life the bones that lie scattered in the Fortress of the Stone Dragon, bones that belonged to creatures much bigger than dragons--and when his friends are turned to stone it is up to Drake to find a way to save them, including his own dragon, Worm.

Diego is under the spell of the wizard Maldred who wants to control the Naga, an enormous dragon that lives deep within the Earth, and plans to use Diego to steal the two keys necessary for that purpose; the first key is guarded by Argent, the silver dragon, and Jean his dragon master, so Drake, Bo, Carlos, and their dragons travel to Gallia to try and stop the theft and break the spell on Diego.

The bumbling evildoers of Team Rocket, Jessie, James, and Meowth, get sent by their boss, Giovanni, to break into Professor Westwood's laboratory and to fetch a jeweled collar for his cat, but on the way Jessie meets an old friend.

Lalo the baby lightning dragon has been taken by Eko, a rogue Dragon Master, who ran away with her thunder dragon years before--now she is back looking to make allies of the other dragon masters, and so gain control over all of the dragons in Griffith.
