The Man in the Desert

"For as long as I can remember, there was a man who lived out in the desert. Some say he is god. Others say he is a demon. There are tales of him saving villages, and myths of his ability to find water. He is a legend that, even now, is told among the children"

This is a flash fiction about a girl's meeting with 'the man in the desert.' Where no one survives out there, what secrets does he hide?
