The Rift

They lived against the northern wall of the Rift, the Bright Face that the sun shone on. To the west the floor of the  Rift rose in great broken terraces to become a white salt desert. To the east it stretched on, following the River, to lakes and kingdoms and past them, march after march, to the end of the world. To the north was the striated red rock of the Bright Face; to the south, at a day's march, was the Dark Face.
