Coral Archipelago

The Coral Archipelago is a group of Island somewhere in middle of the Blue Sea. Because of that position it serves as a relay point for the trade between Grimgar and the Red Continent.

Geography
The Coral Archipelago is a group of islands in the middle of the Blue Ocean. The region enjoys a tropical climate and which can lead to huge storms, typhoons, and cyclones making it fairly dangerous especially for boats.

The exact size of the Coral Archipelago is unknown but it seems to be pretty vast, with some islands being vast enough to support multiple cities, ports, and forests. However, most seem to only be lightly populated. Most Islands in the Archipelago proper are close enough that it's possible to travel from one to another using a makeshift raft.

Unnamed desert Island
It's unknown if the nameless idesert sland on which Yume and Momohina found themselves stranded is part of the Coral Archipelago or if it's just one island alone in the middle of the ocean relatively close to it, the latter being more likely considering some dialogues.

That island is roughly heart-shaped, about 70 square kilometers, with an active volcano on its eastern side, 6 rivers, and numerous tributaries and smaller streams. Most of the center is covered by dense jungle inhabits by some unnamed (but comestible) animal(s). Finally, while most of the island seaside is made up of windswept coast and sheer cliffs, there one sandy beach in the south on the west bank of an indentation roughly in the middle of that side.

The "Titechitike's" island
An island on the outer edge of the Coral Archipelago, it supports a city and a port and serves as a base for the Titechitike pirate gang, the true name of that island is unknown. Titechitike apparently meaning "The idiotic vomit of a devil" in an unnamed Red Continent language.

It seems that most of the island is covered in jungles with multiple streams and springs all over it, those jungles are home to a number of unnamed (but comestible) animal species.

Atunai
Atunai is the largest island of the Coral Archipelago and also seems to be one of the most developed as it has multiple ports with numerous piers.

History
The known history of the Coral Archipelago starts with the Many-eyed people of the Red Continent which seems to have been the first to colonize the archipelago. Then, two hundred years before the event of the series, a flotilla from the Arabakia Kingdom discovered it in turn leading to the first known contact between the two continents.

After that historical event, the islands became a relay point for trade because of their great position in the middle of the oceans separating the two landmasses. While it seems like Ishmal and Arabakia were the ones doing most of the commerce with the Red Continent, their fall didn't sign the end of that activity and it's unknown how much the Coral Archipelago was affected or if they now trade with other countries besides Vele.

Inhabitants
The first inhabitants of the archipelago seem to have been the Many-eyed people of the Red Continent, after the first contact with Grimgar Humans and other races from Grimgar started to inhabit it too. Finally, it's unknown if they were already present on the island during the first contact, but nowadays other races from the Red Continent are also living in the archipelago, notably: Three-eyed people, Tall-eared people, and Long-armed people.

Politic
Almost nothing is known about the politic of the Archipelago, but it does seem that the government, if there's any, doesn't seem to have much authority as a band of pirate (the Titechitike) was able to make a port city in one of the islands on the edge of the Archipelago into their base.
