Atlantis is the lost city.... were you ever a kid? There are different versions of the story. I grew up with:
Many years ago there was a city, a beautiful city where the magestic Draconians lived, mingling with commoners. Draconians were humans who were gifted with wings.. They flew and over looked the city, protecting it from harm.
But after years the Draconians became concieted and power-hungry. They wanted to be thought of a's lords. The mere humans should have to revere them.
So taking the mantle of Kings and Queens they began to rule. But, Zues, who had gifted them this power, was ashamed and Angry. So he struck, raining lightning bolts down on the sky and Posiedan (his brother) raised seas.
Finally, after many days and night the city sank, forever holding it's beauty.
