Atlantis is a lost ancient civilization. The founders of Atlantis were half god and half-human. They created an idealistic civilization and became a great marine power. Their home was made up of islands divided by thick moats and connected by a vessel that penetrated to the center. The people of Atlantis began as moral, spiritual people who lived in a highly developed, utopian civilization. However, they lost their way and became greedy and corrupt. The gods became enraged, and as punishment sent one horrific night of fire and earthquakes. This caused Atlantis to sink into the sea, never to be found again.
