There is a place and time for everything. Even for traveling to a different dimension. There are portals created by things we call, Staries. There are 6 portals ready to take over the world. They are called, Obies, Ramiou, Morphiaus, Werion, Opkin, and Hen. They all do different amount of damage. But the worst, is Hen. Portal keepers must travel in the portals and kill the heart. But, the portal does not stay open for ever. So if they don't kill the heart in time, they will be stuck there, for all eternity.
