You travel for days. And days. After 3, the grasses stop. 2 more, and there is no sign of life whatsoever, and you're out of water; thankfully, when you bed down there is a heavy rain, and by propping up your waterskins you fill them after a very uncomfortable sleep. After another 2, you think you can see something off in the distance... but it could also be just a delusion, a mirage. You're not quite sure. Either way, you have enough food to make it back to the village, but the water is bad; you'll be parched by the time you get back there, if you leave now and there is no rain.
