Here’s one that can go a few ways… My first thought was Atlantis. Or an island chain (a la Earthsea or Moonshae), but look in the bottom center. Is that a castle, or skyscraper-type structure? Is that a force field, or bubble of magic? And off to the right: a landing strip? For some kind of aircraft (Jet, etc) or an aircreature (Dragon? Pegasus?)
What does this suggest to you?
