Brigantium (La Coruña)
Cacera (Vila Real de Santo António)
These are examples of cities with sea lodges... with an ancient history attached to them.
There are more (modern) sea lodges in major cities also where Magicians/Wizards and witches come together to worship sirens (demonic sea-creatures) and to draw power from those marine spirits. Three places in Ancient America (at that time named Atlantis of Columbia) were Itiwana (New York City), Atlantis (Somewhere in present-day Florida) and the Kingdom Califia (today California). Furthermore in the Caribbean and South America were also certain siren portals... where sailors and pirates come for their powers..
The same is going on today.. piracy never disappeard from the Earth. It only took other forms!
