Along the Shore of the Silt Sea - A Dark Sun Fable

Two travelers were walking along the shore of the Silt Sea. They looked out, across the loose silt and they saw something moving above it.
"Look," said one traveler, "a skimmer is rolling in from distant lands. It's bound to be filled with riches!"
The object they saw came closer to the shore.
"No," said the other, "that is not a skimmer filled with treasure. That is a skimmer filled with food and water!"
As they watched, it came even closer.
"Maybe it's a skimmer filled with beautiful concubines for us to buy!" they cried.
The two travelers rushed to the edge of the sea and a silt horror grabbed them. The two travelers were never seen again.
