Artha falls into a trap set by Word Paynn and finds himself deep below Dragon City where he meets the short, reclusive leader of the Dragon Keepers crew. But he is also near the lair of an energy-draining dragon called the Muhorta, which Word plans to use to capture the Dragon Booster and dragon of legend.
Artha Penn (a.k.a.: The Dragon Booster), and his dragon, Beaucephalus, are lured into a trap - turning them into the evil Wraith Booster! They travel across Dragon City, turning the citizens to stone - on a mission to ignite the "human-dragon war"... Their only hope lies with their arch-rival, Moordryd Paynn, to save the day...
Mortis intervenes to save Artha from an elite warrior named Drakkus, but is injured during the fight; Mortis reveals himself as Artha's father (contradicting earlier official information that the two were separate characters), and Artha must find a way to release not only Beau's power, but his own as well.
Moordryd finds a black draconium bone mark called the Vysox and Decepshun absorbs it permanently, growing more powerful. Moordryd also finds a map leading to the Bone Marks of the League of Eight. Will Artha and Beau be able to stop them before the most powerful dragons of the Dragon Human War are released?
Only one more Academy event remains: the Dragon City Academy Dragball Elimination Challenge, but Artha gets badly hurt fighting with the Shadow Booster. Will he take part or will he quit. Find out in the awe inspiring conclusion of Dragon Booster. The Episodes will now continue in: Dragon Booster Academy.
