The return of the Dark Order and their allies threatens the kingdom of Denver and its capital, Menhelm, throwing the world of Orbis into disarray. Led by war chief Bukka, the orcs, goblins, and ogres seek to destroy mankind, and King Deiderick must decide whether to call upon old allegiances or risk his secrets leading to the fall of man. Meanwhile, a group of misfits, including Romulus, the wolf-dragon outcast, a halfling princess, a merman, a pirate, an elf, and a mage, battles the Dark Order. Seasoned warrior Hardwin and Medwenna, the holder of the enchanted Deathbringer sword, fight on the frontlines to safeguard Menhelm. Sean and his father embark on a quest to unite mankind against the attackers by seeking the riders of Underligrvojl and their unicorns. Will these heroes be able to save Denver, or will the Dark Order succeed in their plan to rule?
