In ancient times, the Ancients used "Mind Magic", a powerful force, to create Skylands. Realized that the magic would be easily misused by villainous people, they decided to protect it and hide it in an unknown place. However, years afterward, Kaos, discovers this force and attempts to utilize it to create the world's greatest villain: himself, and a new army called the Doomlanders. Portal Masters, who are extremely concerned about Kaos' act, decided to create their own army, the Imaginators with their own imagination, and that they would be trained by the Senseis, powerful class masters sent by Eon. They must work together to stop Kaos and bring peace back to Skylands.
