Quarium

Quarium is an underwater kingdom inhabited by sea demons. It is located off the east coast of Capellus and is closest to Palstrine. It can be identified by its enormous military base. Their technology is most certainly impressive, but not nearly as impressive as other kingdoms. Most demons here are environmentalist aether users. Most Quarians worship the Sea King, the strongest sea demon on the planet. The King is also Ika's adoptive father.

Quarium is also Ika's birthplace.

History
15 years ago, there was a big project where the Sea King wanted to mass produce soldiers that were genetically altered to be stronger than the average sea demon. As an experiment, 50 thousand eggs were mass-produced using a form of aethertech. Despite this number, only about 8 eggs actually hatched. (Ika was the 8th one to hatch) These 8 demons were highly respected by the Sea King, because he saw them as the strongest in the 50 thousand eggs. They were the only survivors. They were all appointed to directly work under him as they all grew. He basically saw them as his long lost children. Unfortunately, because artificially making eggs consumed too many resources, and the fact that only 8 hatched out of 50,000 eggs, the project was put on hold. The experiment wasn't a complete failure though, the genetic alteration worked. As mere infants, they were prodigies. Because of this, the Sea King wants to invade the surface, Capellus, for their resources so he can produce more eggs.

Quarium Soldiers
Quarium is a strongly militarist kingdom, so most of the residents have had some form of military training. Their military consists of 4 ranks:

Life
Quarium strongly believes in military power, so as a result, most of the kingdom has had some form of fight training regardless of age or gender. You start training at 6 years old at a special school where you get education AND combat training (so it’s very hard growing up). When you turn 13, you get an option to either enter the military or go to high school. If you decide the military isn’t for you, you can opt out of being in the military and continue to get further educated at high school where it’s focused strictly on studies. After you graduate high school you can get a regular job, (however if there’s an emergency for war you have to go and fight.) If you choose the military route you continue getting tough combat training but stop studying, eventually earning a spot in the military as a low ranking soldier.

At a young age in school, you are taught to worship the Sea King and only the Sea King, as one of the teachers' jobs are to brainwash kids to be loyal to him. If, at any point, your loyalty is questioned, they isolate you after school to brainwash you even further with a sort of aether. However, if you're stubborn, one of the King's Soldiers will come into your house at night quietly and kill you, passing it off as suicide, murder, or mark you missing.

Social

 * The horns you have decides your social life. If your horns are long, poisonous, or if you have more than 1 horn (like the king) you get complimented and you're more likely to get hired to jobs and rank up in the military, etc. Horns are really important in sea demon culture and if you have bad horns you'll have a harder time in life.
 * They have a different language, Quarian.
 * Females usually have 2 horns, and males usually have one horn.
