Krev, the last surviving Viking, washed ashore on the island kingdom of Wuling after his homeland was destroyed by the forces of evil. He warned King Yuan-Tao that the sins of Lust, Gluttony, Greed, Sloth, Wrath, Envy, and Pride had grown powerful and would threaten other lands. Krev convinced the King to let him train the people of Wuling in debate and combat so they could defend themselves through diplomacy or war. The King agreed and the Wuling Vikings were formed, strengthening the kingdom and carrying on their traditions to the present day in Taoyuan city.
