FRAGMENT TL-2380 · Green Sahara · ARCHIVE

The Sahara is younger than your cities. Five thousand years ago it was grass, rivers, cattle and swimmers — you have their paintings, on rock, in the driest place on your planet. The drying took roughly a century. Your climate models cannot produce a century. My file records the date and leaves the cause blank, which is its own kind of statement. There is a structure under that sand, thirty-eight kilometres across, in rings. Look inside the rings.
