The Serdin and Kanavan Kingdoms, the biggest kingdoms on the Bermesiah Continent, coexisted in peace until their lands were slowly overcome by the evil Queen of Darkness, Kaze'aze.
Kaze'aze managed to infiltrate the Kanavan Kingdom by murdering the Kanavan Queen's most loyal and trusted retainer, and then disguising herself as him. As a result, Kaze'aze was able to get close to the Queen and entice her with the ways of darkness. Kaze'aze blinded the Queen of Kanavan's eyes to truth and led her to wage a five-year war against the Serdin Kingdom. All of Bermesiah Continent was devastated; many heroes fell in battle, and even the Queen of Serdin sacrificed her life in hopes of ending the fighting.
The death of the Queen of Serdin broke Kaze'aze's hold over the Queen of Kanavan, who, after finally regaining her senses, erupted with fury over Kaze'aze's treachery. Kaze'aze escaped before the Queen of Kanavan could execute her. This lead the Queen to dispatch Trackers to punish the Queen of Darkness. But after years of searching, she was nowhere to be found and the Queen's Trackers vanished as well; forcing the Queen of Kanavan to abandon her search.
The Serdin Kingdom experienced a series of bizarre incidents related to Kaze'aze after the Five-Year War: these events revealed that Kaze'aze manipulated the Kanavan and Serdin Kingdoms into fighting each other. The newly appointed Queen of Serdin is now determined to prevent Kaze'aze from starting another war between the two kingdoms for the sake of the entire continent. The Queen of Serdin has prepared to confront Kaze'aze and counter her evil plans by organizing Grand Chase, an elite corps that will fight for all of Bermesiah.
