Omniverse, it's the largest form of existence, made of thousands of Multiverse, each being made up of singular universes. The simplest way to call a universe is a World. Right now forces from multiple worlds are uniting, evil forces, dark evils that were thought to be defeated, ones that have yet to emerge, and ones revived.

Four young heros must be chosen, to travel across these worlds and counter these forces of evil, they must gain power, experience, Bonds, and Allies. Four brothers, Sean, Connor, Merrill, and Gage. These four must travel the Omniverse and gain the ability to combat evil as well as Friends and Allies to help drive them. This is the tale of 'Worlds Conflict'.
