Prologue

Twenty years have passed since Hiccup became the Blood King and had defeated all who wronged him before he built a Viking empire that has rivaled empires around the world. As Hiccup and his family lead Norway to prosperity, enemies amass to destroy everything that Hiccup has built.

To make matters worse, Hiccup's son has taken a princess of Kiev Russia from the ruler of Kiev. With foreign enemies amassing as well as the armies of Russia, Hiccup will face the greatest challenge of his life as his empire is plunged into the largest war it has ever seen. As Hiccup and the Viking people prepare for the battle that change everything, there is only one question that needs answering.

Who will prevail?
