Basically Medieval England. They have a British accent (which is called a Ravenian Accent), and they are your typical knight kingdom. They are very diverse in terms of race and culture, and are basically the Hufflepuffs of the TSC World.... or are they? 

The Kingdom of intelligence and knowledge. They are known for their French accents, pointy towers, dull and neutral fashion colors, and elitist culture. They are also home to Sanamancers, who make them the capital of medicine in Selyria. 

Battle hardened knights and mages who live in a giant walled kingdom to show their power. This is your badass faction for people who wish to grow in a tough life of bullying and trauma, just to have a very stoic and strict personality of honor and courage. They usually have a Scandinavian Accent.  

The Kingdom of Dwarves. They live under Mt. Ulfenheim and survive through the cold using the hot magma vents of the ice mountain. These Dwarven people usually just come out in the spring, or summer, to hunt or trade with other nations. Other than that, they speak predominantly Finnish but one of their cities speak Polish.
