My nation:
Monarchy of the Mermaid

Note: the big, black circle in the valley is called Nunblable, an university town where research is conducted. I kinda forgot to mark it.
Size: Roughly 7000 square km
Population: 200 000, first-world level wealth, exact number is unknown due to small rural communities.
Military: 500 strong and armed, plus 100 strong as my personal guard and personal enforcers (which pretty much amounts to delivery and massager duty, and occasional parades), with additional 400 support and technical personal that are part of the military but have not partaken basic training. They mainly form to ensure security, both inland and on sea. Note that the military polices the sea for predators and helps scientific research. The Floating Base, a recent technical achievement given by allies, helps support passing-by military ships by both repairs and fuel and ships in distress. Even friendly, non-allied ships may dock, for a price.
Economy: Over 20% fishery, 30% agriculture, 20% service and remaining percent industry. There is no real export of note, except perhaps birth-control products, some exotic foodstuff and certain... art. Also, there is a vain of rich, heavy materials in the mountains due to volcanic activity that is currently mined and refined. It is not a significant industry as of yet, as the efforts for it are more explored then used.
General tidbit :The name comes from an old legend that is supposedly from the island's founder. The story is a bit long, but in essence, it involves a horny mermaid helping a lost ship find this island. The mermaid supposedly stayed as she fallen in love with the first tribal leader (she was able to change its fins to legs when wished, in case you are wondering). The island was large enough for its economy to grow and eventually reached a point where it was able to form a central government.
History: Thankfully, the island's history is quite bloodless, apart from a few incidents in its distant past due to food shortage. Each new settlement was founded quite early and after taking opportunities in that area. For example, for a long time, Kiki village was a summer resort for most of the time, picking and tending various fruits over the summer.
Otherwise, most of the island's history boils down to various business between various towns and villages, a romantic tale here and there.
Religion: Freedom of Religion protected. There is one monastery that now serves more as library and tourist attraction. There were a few Churches but most are abounded, with the exception of one or two.
Noteworthy is the local polytheist religion, that still survives in the more rural areas and has smaller followings in the cities. This by itself may look rather harmless, as it is mainly hedonistic, but there is a history to them regarding violently-held polygamies. While most practitioners are casual and actually just use the religion as an excuse for their hedonistic practises, police still keep a close eye on mayor followings.
Infrastructure: The Kingdom of the Mermaid has its main farmlands next to Cupil, its two main fishing towns being Callipo and Lunda, Callipo a harbour being open for trade. Lunda also houses a research facility for the Lungfish and Saber project and serves as a landing strip.
The town's roads have been improved over history and are in a state that one with a bicycle can leisurely get around the entire island under a day. There are no cars on the island, however motorcycles are popular (although, I do encourage bicycles for casual travel). There are small trucks that currently transport goods between the islands. A railway system is planned for transporting goods, but we do not have the expertise and necessity to produce it.
Note that small communities also live in the large jungle, these are unmarked as these are usually insignificant and hard to keep track of. Scout towers and ranger huts are also not marked on this map.
Power: One may notice the radiation symbol, the island's sole power plant that supplies over 70% of the power, it is called Mugave, the son of the volcano Hangave (the volcano has been dormant for several centuries). Additional power is drawn from government sponsored solar panels and wind farms near the coast. Some geothermal plant plans have been also made, but are rejected as of yet due to the fact that the island has plenty of power.
Request regarding map: Put me Northwest of Surlethe's island/continent.
EDIT REASON: Gah, curse my spelling.
