Imagine an hourglass, except rather than measuring hours, it counts out aeons. Its circumference is
25’000 miles. The glass walls are 60 miles thick. The sand within forms a desert almost 8’000 miles
wide edge to edge.
The peoples within know not where they came from, or why, but all know where their end lies; the sinkhole
in the centre of their world, 200 miles wide and forever growing as the 600 mile sandfall that encircles it
erodes away the mountain-high perimeter. Even a hundred miles away, dunes collapse seemingly for no reason
as the sand shifts a thousand miles undersand.
