The Eternal Menace

It's been twenty years since the Guardian Sages brought a bit of balance to Earth. But ever since their devastating separation, chaos has spread tenfold. When an explosion sends Kwon rushing home from town to check on his grandpa, he gets there only to find a crater where a ranch once lay and his deceased grandfather lying in the center gripping a strange medallion that he's never seen before or heard about. Hoping to find the meaning behind the item and what it has to do with his grandpa's death, he goes on a journey to find his grandfather's best friend, Goopa. But he soon finds out that the medallion was not the only secret his grandfather hid from him. His grandfather was a member of the legendary Guardian Sages. Now, with an enemy from the past carrying a vendetta and the remaining sages being exterminated, who will protect the ones that once protected the planet?
