He climbs until his limbs tremble, and his ears pop, and each breath he takes feels thin.
And then suddenly he emerges, and the dune falls away to reveal something like the desert stretched out before him like a living map.
It's hard to see, with his dry scratched eyes. Like looking through gauze.
Over there, distant, a field of twisted things like huge crumbling knobbly bones, tangled together and flaking death; beyond it a city that lies on the plain like a tumour; over there, a land of bubbling garish vomit-colours, strange vapours and boiling lakes of sulphur; over there, a great black citadel that pains him to look upon; over there, a ravening thing bleeds poison ichor into the great river; an eyeless city older than history broods in the deep desert; uncounted ruins among the sands, of cities each greater than any that survives today; the lost treasures of the old world glinting in blasted valleys; the three Reclaimed Cities he has heard travellers whisper of, gleaming palaces perched atop a gnawing abyss; in the far distance, an island in green where elves play.
