It's a chilly morning in this patch of desert. Golden dunes stretch out in every direction, with purple shadows clinging to their slopes as the rising sun pokes its head up tentatively over the horizon.

To the west, there's a small grey-green cactus, round and spiky. To the north-northeast, a patch of what look to be some very dead trees. To the east, just the sun; to the south, just the sand.

To the southwest, a faint scent of water, and a tree in the distance that might have some life left in it.
