Overworld takes place in 4998, a time of great change in the galaxy-spanning empire. A time of great change and great uncertainty. A new emperor has finally been crowned after years of warfare and conflict- but his rule is not yet stable. Years of warfare has decimated the once-proud empire, and social stagnation has resulted in an outdated caste system that engenders feelings of resentment and anger in the oppressed lower class. Though widespread violence has not sprung from the undertones of rebellion, it is just a matter of time.

At least, it was just a matter of time. A new form of entertainment has been discovered- one that crosses caste lines and takes proles and nobles alike from the grim realities of their everyday lives into the high adventure of actors- into their very minds and bodies. The empire now has its gladitorial arena, and it is called Overworld.

The planet Acacia-6, is a world that has no intrinsic worth other than the fact that it is the home to a multi-billion solarii Entertainment Guild venture. Slightly out-of-phase with Acacia-6 is the fantasy realm known galaxy-wide as Overworld. It has all of the elements of high fantasy, including a force akin to magic. Though this alternate world has no intrinsic worth as only biological matter can be transmitted, it was a gold mine to the Entertainment Guild. Actors now risk life and limb for the entertainment of billions throughout the empire, in adventures in Overworld.

You are such an actor, trained and commissioned by the Entertainment Guild. In Overworld, those actors that prosper become immensely powerful. But in the real world, they are still faced with the reality of being a lower caste citizen- even though they enjoy many of the advantages of upper castes. But popularity can sometimes be its own powerbase...
