The desert of fallen stars

“The sand of the desert of Yondo is not as the sand of other deserts; for Yondo lies nearest of all to the world's rim; and strange winds, blowing from a pit no astronomer may hope to fathom, have sown its ruinous fields with the gray dust of corroding planets, the black ashes of extinguished suns. The dark, orblike mountains which rise from its wrinkled and pitted plain are not all its own, for some are fallen asteroids half-buried in that abysmal sand.”
