Serra do Mar

Serra do Mar (海峠, Umitōge) is an archipelago or a chain of islands that consists of three fairly large and four small islands located near the southern tip of Ishgar.

Description
Located several miles away from the southern tip of Ishgar, Serra do Mar is perhaps the largest chain of islands ever known to mankind. The islands are remote and can only be accessed by boats or ships. Aside from having three large and four small islands, there are also over ten Islets near this chain; making it a great tourist attraction.

Trivia

 * Serra do Mar is actually a 1,500 km long system of mountain ranges and escarpments in Southeastern Brazil.
