Eventually we found evidence of dwellings here under the sand: widespread but shallow traces of what looks to have been an early space age civilization. Their buildings were obliterated; even the most substantial among these ruins have been razed down to their foundations. However, chemical analysis shows the desertification of … came some time after this planet-wide annihilation. Much of what we have been forced to dig through so far is the atomized remains of construction material. Many of the faint outlines we have traced along thoroughfares in this former city are bisected by the lip of a large crater - remnant of an apparent impact site.
