To save his father and the narwhal's kingdom from a vengeful sea hag, Prince Asgar must overcome his insecurities and learn to be a hero from a legendary warrior who may not be the best role model.

The sea hag, once beautiful and a powerful friend to the Mighty Men of Arctinrod, now seeks to conquer the narwhal kingdom with her massive kraken octopus. In this sequel to Legend of the Narwhals, Prince Asgar leaves the icy fortress of Arctinrod with his father, King Olaf, and the Mighty Men to find and stop the hag on a remote tropical island.

When the hag casts a powerful spell, making the Mighty Men fall in love with her, leaving them defenseless, it's up to Asgar and the legendary warrior, the Mighty Skarde, to rescue them. Since Asgar has no fighting skills, Skarde and his powerful club, Battle Bright, are their only hope. But the hag proves to be a formidable foe, fighting with spells, storms, water cyclones, and her massive octopus.

With the fate of his kingdom hanging in the balance, Asgar must join the fight and summon the courage to be a hero like the Mighty Skarde. But he soon learns a valuable lesson: not all heroes are worthy of worship, and true valor comes from within.
