Basic Idea would be that there are more than one Dimension/world, and it's possible to jump between them when you're gifted with "The Jump". It would involve different realms, worlds, and the adventures of the Jumpers going on their nonstop quest to build peace. It would be humans, or make your own race. In the end it would be discovered that the "Locked Realm" (which houses all criminals/terrorists/warlords/what have you) has been opened by an Immortal figure. Now leagues of evil plague the realms, and it'll be up to us to stop them!
