Once there was a village where babies and kids had to live outside the cave in the sun world. Only when they were old enough could they live in the cave and as each person got older there were deeper caves to live in. The oldest became the blindest of all and craved nothing but darkness and silence. Food and water were passed along to them through the chain of the ages, as they called it. Those who did not follow this order and feared this willful progression toward blindness were threatened with endless wandering and no chain to depend on.
There was a man who disregarded the warning and ran away. He found other villages with other ways of living. He would go from village to village in search of anything new to learn until one day, village after village, had nothing left for him to know. And that is when he realized that he had already entered a cave within himself. And he wondered if his people were right all along and it was he that was foolish not to listen to them.
And when he was older he returned to his home and they were happy to see him again and they let him go as deep in the cave system as his age would allow. And there they fed him something he had never had before. Something held secret by the elders. And new visions appeared within him of not only of villages but worlds he never could have known outside the cave in the sun world.
And when he slipped back into the great fold, as they called dying, he had gone to the deepest cave yet and passed along stories that helped his people deepen their understanding of their chain of ages
