In the metropolitan city, Empyrean, a sudden glitch resembled the sounds of hell. An omen. It came from a rumble underground, and soon enough, all the lights flickered and the electricity went down. Chaos erupted. Monsters emerged. Empyrean is a city where the people can conjure the elements of earth, fire, water, and air with the use of their weapons. As chaos unraveled, a group of teenagers must survive with their skills while discovering the truth that's hidden beyond sight. Of a history. Of a war. Of an oppression. All these would result in them altering the world.
