There is a city by the sea. In this city are many who have forsaken god. The residents of this city have placed before themselves false idols of materialism and conspicuous consumption. One day the populace will watch, bemused, as the sea recedes as if withdrawing from the city. Then, however, their bemusement will turn to horror as an enormous wall of water comes rushing toward their immoral city. Too late will they realize what is happening, and all will be lost as the gods take their vengeance.
So the next time a tsunami hits a populated area, don't forget that Baby Fatt prophesied it first.
This metropolis is home to artists, musicians, and storytellers. Its people work in many trades and have grown fat from abundance. In their self-satisfaction they have forgotten the importance of paying heed to the gods.
Soon, a day will come for the gods to take their revenge. The earth will shake and roar. The ground will open and many will be swallowed. Fire will spread and consume structure and being alike. Destruction on a scale seldom seen will be visited upon the ungrateful wretches who turned their back upon their gods.
Remember: the next time an earthquake hits a city, Baby Fatt prophesied it.
See the trick? Prophecy is easy. You look and the past and then infer that the same stuff's going to happen at some point in the future. You word it sufficiently vaguely to be able to take credit for it wherever or whenever what you've prophesied might occur. Thus is a prophet born.
Prophets are used-car salesmen. Those who buy their wares are idiots.
As for Baby Fatt--I gotta get me some of those vestal virgins.
