EXO Planet was a beautiful planet that consist of 4 Kingdoms: Water Kingdom known as Aquamarine, Earth Kingdom known as Gaia, Wind Kingdom known as Zephyr, and Fire Kingdom known as Pyroglea. Beside the 4 Kingdoms, there’s still 2 Free Travelers Tribe that always move through the planet. They are the Time Traveler known as Chronoseon and Light Traveler known as Hyperion.

As long as the planet age, the 4 Kingdoms and the 2 Travelers Tribe always live in a harmony. Aquamarine which located at the North Pole, where the Water Tribe live, and the South Pole, where the Ice Tribe live, of the planet is surrounded with oceans and glacier and be the source of the seafood and the water supply for the planet. Gaia which located at the equator where most of the plants and animals live there is the source of food for the planet. Zephyr which has a lot of mountains and flower fields is the best place for study because it’s being the home of the wisest people of the planet. Pyroglea which surrounded by volcanoes chain is the place where technology is advance so it’s being the source of the planet industrial area. As Chronoseon is moved through time, they are respected as the story-teller which tell about the history of the planet and what will happen in the future. While Hyperion is moved where the sunlight lightened right in their head is known as the enterpreneur of the planet.

The nighmare began when the king of Pyroglea thought they need more minerals to make the things for their country. They need more iron, metal, and coal which Gaia posses. They need gold, diamonds, and the knowledge which Zephyr posses. The mystery went to Aquamarine, since the land was covered with very thick ice and deep ocean, but they suspect Aquamarine has a lot of petroleum hidden under the thickest ice and the deepest ocean.
