Atlantis was once the most powerful nation on earth. But in one night it sank. It is now the undersea home of the Atlanteans. 


Atlantis' ruler Aquaman recently decided to abdicate the Atlantean throne.

Aquaman discovered a holographic transmission from an ancient Atlantean who said that the city was in danger and that his forces had pursued an unknown enemy to the oceans. Before the transmission ended, the Atlantean further said that this enemy was planning to sink Atlantis and claimed that the king and queen of Atlantis had hidden the truth.
