Man built the city. The city grew and prospered. Then man began ignoring the sea gods, so the sea gods destroyed the city.
The sea gods ordered another city be built and it was. As before, the city grew and prospered. Then man began ignoring the sea gods again.
The sea gods destroyed the second city.
The sea gods ordered a third city be built. Man fled from the shore.
