From Miran Cache #25: An extract from a letter to a merchant in Suojo, from her agent in Lop Nur:
I persist in my efforts to purchase the grain that we need. While the soldiers of the Green Banner Army of the West only provide escorts for the caravans of the Middle Kingdom, guards are readily available for hire here. Though there is much fear of bandits, do not concern yourself. The locals are much more experienced when dealing with the desert, and more reliable. We shall be safe in our travels.
