When Leiyu, a wandering warrior and wind mage from the Eastern Region, rescues a trade caravan from a horde of bandits in the desert, he does not realize how much his life is about to change. He learns that the caravan merchants are heading westward to the Kingdom of Ishkhandar, and he offers to join them as a bodyguard.

After arriving at the royal palace, Leiyu ends up meeting the mysterious Prince Thallios. The prince is both whimsical and melancholy, and yearns to see the outside world. They spend some time getting to know each other, but everything is thrown into chaos when Ishkhandar is suddenly invaded. King Xenon tells Leiyu to escape with Prince Thallios and to protect him with his life. He also tells Prince Thallios to seek out the legendary Sword of Ages so that he can come back and avenge the doomed kingdom.

Now on the run, Leiyu and Prince Thallios trek through the wilderness in search of the legendary sword. However, the quest does not go quite as planned.
