In the indistinguishable darkness, where all void was the same, and there was no layer to it, and nothingness was everywhere, in a key and distinct location, where was a single flaming sign. Bright red and emblazoned with a great 'EXIT' on it, this sign hovered over the nothingless as if it was the sun in the sky. Though it was clearly visible, it emitted no light whatsoever, and did not illuminate nor show any sort of 'exit', and it almost seemed like a red herring purposefully places there to instill false hope. That's how all of the Zero Worlders took it, anyway.
They longed and begged to escape, and the sign was always out of reach, despite being so large and clear and seemingly close. There were no dimensions here, and that meant there was technically no depth nor distance, so no matter how much the Zero Worlders tried, they could never reach the Exit sign that was always overlooking them.
Desperately, they tried, moaning and wailing and carrying on, climbing over one another in the void, reaching for it. When they got tired, they left, but all day, every single day, Zero Worlders came to the Exit sign like it was some kind of deity, and religiously reached for it, and even designated time to do so. There was nary a person in the Zero World that hadn't or didn't go up to the great Exit sign and seek its salvation.
None ever got it; all kept returning, however -- hopelessly so.
