Dear sir,
Allow me to introduce myself. I am Costner Meyers, and you may have heard of me. I have reason to believe that a valuable resource lies beneath the ground you own, and I would happily negotiate a deal with you. For, you see, it has been preordained.
Recently, I was struck by a vision while searching for water. I became disoriented in the wild, my mouth as dry as sand -- but at last, I was blessed by a visit from some sort of a hovering phantom. You might think this to be a hallucination, but it gave me water and bestowed me with unlikely insight. The Kindlewastes are deadly, but the Mysterious Wanderer says there's hope. The land hides liquid gold inside!
You must believe me. Do not test my faith.
Signed,
