History

While Aquaman was searching for information about the discovery that his mother had not died, he discovers that there are a series of Atlantean portals that communicated different locations on Earth and other alternate dimensions.

Because of this, he manages to access Pacifica, a temporal dimension that transferred the person who passed through the portal to a prehistoric version of the place. This is where his mother Atlanna was, who was now the protector of the people of Pacifica. It is also the home of the Fire Trolls and the place where Karaku, the Volcano God, lives.
