Sometime later as part of the Marvel NOW! event, Attuma found and unlocked the secrets from the Lost City of Lemuria, using it to attack several places on land.
Richard A. Lupoff's novel Circumpolar! describes a flat planet much like the Earth as described by the Flat Earth Society, except it has a hole at the centre instead of a North Pole, and the underside contains fictional lands such as Atlantis and Lemuria.
She is the daughter of Llyron, a member of the water-breathing Homo mermanus who dwell in Lemuria, and Rhonda Morris, a surface woman who inherited her father's oceanarium in Hawaii.
The humans who moved there discovered the first secrets of magic, and through magic they created the mighty city-state now known as Atlantis, Meru, Lemuria, etc. though its true name has been lost to time.
