After discovering the cause of the dragon raids in the Archipelago, Hiccup and Toothless slay the Red Death, but not before the young Haddock promises Astrid that he'll return one day stronger than ever before. It would take fifteen years for the young dragon rider to return, for he has been forged into a man, in a land called Persia, where he learns how to fight, lead armies/people, learn politics and other necessary skills. But during his time away from Berk, Hiccup makes powerful allies and enemies. An ancient evil is once again reawakened; demons called the Djinn. The Djinn have taken both man and dragons to increase their ranks to create an untouchable dark army, their leader Ghul, thirst for vengeance and darkness has consumed his reason, sense and conscience. Now Hiccup and a group of young men and women called 'The Inquisitors' are tasked to end the Djinn plague as it makes its way to the North... The Archipelago. Hiccup along with the Inquisitors and half of the imperial Persian army travel North, they must stop the Djinn in their tracks before they lay waste to humanity.

Snotlout Jorgenson and his lackeys do the unthinkable and assassinate Stoick the Vast and frame Hiccup for the crime, thereby banishing the heir of Berk from his home. Hiccup is sent to Outcast island and meets Alvin the Treacherous and his hordes, but the Outcasts soon learn that Hiccup has a gift. The ability to tame dragons. Hiccup tames a Night Fury with all the Outcasts watching, and with that, they all vanished without a trace. The boy finds the most ruthless and most bloodthirsty Vikings in the Archipelago for one goal. Conquest. Hiccup's army of Vikings and dragons invade Europe and their goal is to become the most infamous and legendary Vikings in history, and Hiccup himself will prove to the world he's made himself strong and becomes a conquer. Hiccup Horrendous Haddock III will become 'Hiccup the Accused.'

Hiccup Haddock is the laughing stock of Berk, Stoick's little embarrassment and the only Viking heir who has yet to kill a dragon and Astrid Hofferson is a disgraced young warrior who does everything in her power to restore the Hofferson name. Together, both Hiccup and Astrid try to do right to their family names and tribe, but their efforts are fruitless, the Hairy Hooligans want nothing more than to dispose of them. The two Viking outcasts are then branded as traitors because they were discovered befriending a Night Fury, and they are accused of false crimes that further seal their banishment. No longer fit to live among the Vikings of Norway, Hiccup and Astrid set out to start a brand new life into the great beyond. Little do they know that their adventures will soon land them in a foreign land filled with new dragons, dangers and a war torn empire.

What if Hiccup had left after being chosen to kill the Monstrous Nightmare. After three years of being presumed dead and freeing dragons from in and out of the archipelago and building his reputation as the man in dragon scale armor the Night Rider, the thief of the Vikings... what will happen when his quest brings him back to Berk? What will happen when the "Night Rider" becomes involved with problems around Berk? And what happens when he runs into an old love interest. Through fire and flames, dragons and destruction, pain yet persistence. What will happen to Hiccup and his best pal Toothless, and will he choose his role as heir to Berk, or the Night Rider...
