On a trek through an unforgiving desert, starting point and destination are indistinguishable from one another. Terracotta-hued dunes twist and writhe, their shapes ever-shifting. Only the merciless sun and aloof constellations can be trusted to point the way. Weighed down by treasures some tempting the eyes with their glittering sheen, others enticing the taste buds with exotic aromas the camel plods toward a far off marketplace. Water is but a dream for now, the taste of sweet dates a distant memory. There is nothing but an endless ocean of sand.
