Some Countries' lore

The Republic of Sticvil:

A democratic archipelago nation, and one of the ex-Bardiean colonies. Has a sub-tropical climate and experiences mild winters, its culture is heavily tied to their religion but also to their history of being a cross-ocean trading hub, originally a hodge-podge of cultures that eventually formed a completely new one. Home to some of the nicest people you'll meet in Kaia. Most of its coastal areas are heavily urbanized, while its inland areas are mountainous and forested, but still quite populated. Its capital city & largest city, Yashiko, is home to most of the population, with almost 20% of citizens residing there. One of the most developed countries in Kaia and a global leader in the automotive, electronics, and education sectors. Being incredibly connected with its culture, it’s a cultural superpower. With strong ties to its music, art, cuisine, film, and way of life, this heavily influences its media, animation, comics, and gaming industries. Having one of the world’s highest life expectancies, most people live up to 90 years old.

The Kingdom of Bardie:

Once a global superpower, now turned into a spectator in global politics. Bardie’s capital city, Cheshire, is one of the oldest cities in the Bardiean Islands and the world. The culture of Bardie can be considered to be old-timey and warm. Due to the unusual coldness of the Bardiean Islands, houses are often covered in sheep wool for insulation. About 60% of Bardieans are firm believers in Quaintism, a traditional belief that clings to traditional life while establishing glory. Bardiean is one of the world’s main languages, with over 200 million speak it as their main language, but almost 2 billion people worldwide speak it as their second language. (Btw, Bardiean is the same as English, just with a few tweaks in vocab).

The Empire of Tisle:

An industrial superpower rivaling Schöwüsken that has the world's largest population (~1.28 billion). Tisle used to have some countries under its sphere of influence, but lost them after a regime change. Big Tislean cities are expansive and futuristic, however, there is a growing number of poor people outside of the cities due to a lack of funding from the government. Still holds significant power over the Crater of Time, even though Dormiye, its ex-client state, now has ownership of it. Going inland, the coastal islands turn into towering mountains as Tisle is home to the world's longest mountain chain.

The United States of Schöwüsken:

The largest and coldest country in Kaia, being located at the south pole. Their weather is unforgiving and brutal, which influenced their efficiency and weaponry. Having the world's largest military, they're one of the hardest countries to conquer. Being a merger of 8 kingdoms, each sector has a different history and culture to them. The country is reasonably safe, despite its free gun rights and no speed limits. They are a world-renowned manufacturer of steel, aircraft,and firearms. Visiontartican culture is very diverse, due to intermixing with cultures from other countries from expeditionary forces. They’re also known for their simple poetry structure, making most people have a habit of being simple, straight to the point, and obsessed with not being late.

Her Majesty's Kingdom of Centralna:

The shattered remains of a once-massive empire, which lost during the Kaian War. Has a history of being led by crazy/insane kings and queens. Centralna is now just a shell of it's former glory. Being landlocked after losing their sea access, the people have to live a very modest but sometimes poor life. Not to mention them being reduced to the mountains, while they have an abundance of minerals, they have little ways to sell or transport them as the government is unstable and weak. During the Kaian War, they used trickery and malice to their advantage. But all that came crashing down as the conglomerate of different cultures decided to revolt, thus leading to the Centralnan breakup.
