Wow! Okay, these are the 5 countries in Arios. The continent itself is called Adenor, and I can explain how a bunch of the countries are, there'll probably be some words you won't understand but don't worry I'll explain that too eventually!
Terra is the home of both humans and arias, it has many terrains good for living and farming but has no crystal sanctuaries therefore relies on other countries for crystals. Terra is also the most neutral country with the most diverse population, most come to this country to visit the capital of Adenor (Cecilan) as well as the Divine Marketplace. There are plenty of villages placed all around Terra due to the large population, the largest out of all the countries. The climate of Terra doesn't change too drastically, during the summer it's incredibly warm then in the winter it drops to colder temperatures such as -20 to -30.

Icaros is where chiri live, oculo also tend to live in Icaros but they're not as common as chiri. Icaros has the second largest crystal supply compared to the rest of the continent, leading to them not needing to rely on others for crystals. Large craters and ravines are a usual sight that is caused by the larger species of chiri, there are also many natural caves within the mountains. Visitors tend to go to Icaros for the views and beautiful sunsets. Villages are rather uncommon in Icaros due to the mass amounts of people with shifter magic, permanently shifted people, and other creatures, the villages that ARE there are usually in the trees, built into the side of a ravine, or in the valleys. The temperature in Icaros is quite warm in all seasons but winter, in the winter Icaros is just cool.
Resources: Crystal, sandstone, gems
Everine is the country that holds the liluna. It's a mountainous land with a few crystal sancutaries, therefore it can sustain itself (with struggle) but still slightly relies on other countries for its supply. Due to the amount of mountains, villages tend to be near the water or in the mountains. People don't often go to Everine because of the tough-to-maneuver terrain and deep, maze-like forests that would leave visitors trapped and lost for years. Even with these issues, the population of Everine is the second highest in all of Adenor. Everine is a fairly chill country at all times of the year, but drops in temperature around wintertime.
Resources: Rock, minerals, gems
Solaris is mainly populated by ferin, as well as smaller oculo and chiri. Solaris has the largest supply of crystal, therefore they supply most of Adenor with the resource. Solaris has many cliffs, ravines, and large crater formed naturally in the forest, yet most tend to visit to look at the crystal sanctuaries and beautiful night sky. Vilages in Solaris are most often in the trees above the ground, many villages are even within the crystal sanctuaries themselves. Solaris has the third highest population, it's also warm around all times of the year.
Resources: Crystal, wood, plants
Misen is an incredibly barren country, it only holds oculo and outcasts. There is only one crystal sanctuary, but only Icaros and Solaris are willing to trade with Misen. There are many villages in Misen, most commonly in the fields and around lakes. Misen has the lowest population and the highest crime rate, the climate is quite chilly and not too warm
