The planet Ragna is one of the many planets similar to Earth in environmental structure, home to the Ragnan people as well as sea creatures, some of which are amphibious in nature. In the beginning, there weren't many landmasses around the planet.
An Emigrant fleet settled here some years later and altered the topography to a certain degree. It is unclear whether or not there were conflicts in between, but as seen in 2067, the Ragnans seem to have coexisted well enough with the emigrant citizens.
Ragnans are seafaring folk by nature. Many of their houses are made on ships. Their main cultural symbol is the jellyfish: The Barette Jellyfish is a popular delicacy that can be eaten cooked, raw, or even processed into jellyfish chips. The spicy version of the aforementioned snack is a sought-after limited seasonal item.
Their most common produce is the Sea Apple, which is salty compared to Windermere Apples, but tasty in its own way. Bananas are often fermented into wine and is an exotic drink that goes well with a lot of food.
Aside from jellyfish, Mercats are seen everywhere in and out of water. There are numerous products made in their image, the most proliferated of which is the Mercat mobile phone which is available in several colors. 
One notable traditional Ragnan celebration in particular is the Jellyfish Festival. This event is held during the first full moon in September when jellyfish come to the surface to lay eggs. It is said that a couple that confesses their love to each other underneath the floating jellyfish swarm will stay together for life.
In death, there is a Ragnan practice of making a miniature ship for the soul of the person to ride on. The loved ones of the departed drink and reminisce on a nearby coast, later sending off the soul to sea with farewells. Once relieved of sin and pain, the soul is believed to be reborn as a jellyfish.
The original name of the main Immigration Fleet Island that settled on Ragna. Connected to the mainland by several bridges. Currently referred to as Barette City, the central city of Ragna.
