The old world is buried beneath the dunes. For those who live above, life is short, miserable, and piteous. But it is still life. There are families here. Brothers and sisters and neglected moms and forgotten fathers. They make what life they can, ignored by the gods. Which is worse than being tortured by them.
They build what they can from the scraps of old. They bring up trinkets from the past and they hammer them into a tenuous future. And those who make this happen are the divers. The sand divers. This is their world. Hold your breath and join them.
