Great questions, thanks for asking! 
Mylair is one of the three global powers from the planet, Meravtha. They are lead by a monarch, whose symbol is the green crown. The green crown has a few meanings, but the most common are of prosperity and wealth. The empire is well-known for their metallurgy and production of weapons. The yellow represents their size as the country has a saying that when dusk falls in the east, dawn rises in the west, This is mostly an overstatement, but their country does cover a good portion of the globe. They are known for their language and it’s common use as other tongues of the surrounding area have borrowed from it in the past.
Mylair itself is in a time of peace at the beginning of my planned story line. At that point it was more focused on trade and accumulating wealth. Later in the planned story, war does break out and Mylair is one pf the superpowers in that war. They’re almost a like a European medieval Persia, with their conquering. During the end of the war, Mylair invades another country called “Gathens”, which held a supposed artifact. The artifact was revealed to be a giant gate, which was sealed shut, and controlled from Mylair from that point.
There are many different people in Mylair, seeing as it covers parts of three different continents. In this world it is filled with seven humanoid species, though no humans actually exist on this world, called Meravtha. The species are the High-born, the Roylans, the Humrans, the Diakae, the Flesligings, the Roclurs, and the Dragnir. All the species/races are different from each other and often show disrespect for each other. The Roylans are main political power of Mylair, easily identifiable from their glowing symbol above their shoulder. They all share unique traditions and ways of living.
The main Ideology of Mylair is what is presented by the Monarch. They tend to believe in strong or noble knights who will keep the peace, so that the people can live their lives. They are generally open to other cultures, and allow countries that they conquer to live as is, as long as they follow a following set of rules, made for all conquered countries. They won’t attack carelessly or without reason either. They mainly go to war if provoked or have a good/decent reason to. They also believe that one’s natural connection to the magic system, megas, determines their rank in society. Most Dragnir have low affinity for megas and are looked down upon.
I hope this helps. Let me know if you want more, or have more questions.

the political map is a tiny bit old and is missing a island chain, I’m currently working on an improved version)
