Cheongsu (FT)

Cheongsu is the third planet in the Cheongsu System, which orbits the star Vajra. An oceanic planet, 90% of Cheongsu's surface is covered by oceans, with only small island chains and atolls dotting the planet's surface. Cheongsu has a habitable nitrogen-oxygen atmosphere, but features extreme temperatures that can be hostile to life on the surface, ranging from 53 degree in the equatorial zones to negative 70 degrees in the polar ice caps. Hurricanes often run unchecked across the oceans, with winds that reach up to 250 kilometres per hour.

Governed by five states which are members of the Federation of Sovereign States, Cheongsu's population of 1.29 billion people are mostly located on four very densely populated island chains. The rest of the population resides on 65 mobile floating cities called Keunokseon (큰옥선), which are considered modern engineering marvels. Rich in biodiversity and natural resources alike, Cheongsu's main industries include deep-sea resource extraction, farming algal blooms and other seafood, and scientific research. Cheongsu is recognised as one of the premier scientific capitals of the Human Sphere, and is home to numerous international universities and research facilities, many of which are located underwater.

Ecology
Pod Crabs are a mostly benign species of non-sentient creatures native to Cheongsu's atolls and island chains. These large arthropods stand between half to one metre tall, with four segmented legs supporting a bulbous, shelled body. They feed on coastal mollusks and lesser arthropods, and can become violent and territorial during mating seasons. The meat of pod crabs is widely considered to be sweet and tasty, and pod crabs are often farmed for their meat, though farmed crabs generally taste less sweet compared to wild crabs due to the absence of certain nutrients in their diet. Farmed pod crab meat is often used to make mock crab meat products.

National Guard
Unlike other member states of the Federation, the five states on Cheongsu do not maintain their own state defence forces, but collaborate to fund and equip a planetary-level organisation, the Cheongsu Marine Enforcement Agency. The CMEA, also known informally as the Marines, is a supra-state law enforcement and defence agency responsible for law enforcement in international waters as well as planetary defence. The headquarters of the CMEA is located on the equatorial island of Festung.

A traditional Cheongsu saying maintains that where there is a sea, there would be pirates (有海就有海盗). Aquatic piracy and crime on the high seas are a minor problem on Cheongsu,
