Waystations
Follow the caravan from its last reliable well to a settlement half buried by the wind.
The First Well
Load the water you can carry before the ground heats. Mark the ridge and the low road on the same itinerary.
Salt Road Crossing
Send a scout to read the stonework before committing the pack animals to the detour.
Evening Camp
Reckon with the water spent on the crossing and decide how much ground you can cover tomorrow.
