In the period between the Sub-Mariner’s recovery of his memory and the reunification of the Atlanteans, he established a retreat off the coast of Brazil. This was sometimes known as Namor's solitary place. This villa would later be the basis for the creation of the city-state of Deluvia after Namor had been banished from Atlantis. It is where he married Marrina.
- Identified as being located just beyond an abandoned Atlantean city in Fantastic Four #6.
- Deluvia - undersea villa, former secret base of Namor, later populated by Atlanteans who chose Namor over Attuma, kingdom of Namor and Marrina.
