Atlantis

Atlantis was a large continent or land mass that sunk below the sea many thousands of years ago. There are at least two Atlantean cities that survived the destruction of Atlantis, of which are protected by large domes. One city still exists in under the Atlantic, ruled by Aquaman. Another surviving Atlantean city is ruled by Queen Ocina, who commands an all-female army in an attempt to conquer mankind. This Atlantean island is able to move about throughout the oceans like a submarine, thanks to the technological wonders of the Atlanteans. It is unknown if any other Atlantean cities had survived the destruction of Atlantis, but it is beleived that the ancient ruins of one such city was discovered at 721 miles northeast of Honolulu, below sea bottom, and deep below the earth's crust, in the uncharted center of the earth, which Wonder Woman suspected must have fallen through a sea fissure and ended up there.
