The idea of an airport was mentioned.
I like the idea of a swamp. Not unlike "Dagobah" in The Empire Strikes Back; danger, mystery, adventure, etc...
Combining ideas here, some swamps are right after the airport this is in the event that the plane malfunctions/crashes at take off or landing it won't destroy buildings, infrastructures, homes, people, ...
Where to put an airport and a swamp nearby?
With the above map maybe west and northwest of Croatoa.
