#telmar.

ARCHENLAND: Tropics, non-seasonal, with a grand city carved into a mountain that spans from base to a large shrine at the top for traditional ceremony. Not much for hunting, and hold a very vegetable & fruits based diets, though are good rearers of cattle and fowl. 

CALORMEN: Desert. Oasis-dotted, rich city ( grand, yet contained within the small amount of lush life there is in the desert ). They rely on the ( not-so-timely ) rains that come from the way of Telmar. Amazing horticulturalists, and tend to head developments in those regions.

NARNIA: Seasonal. The largest amount of diversity on the mainland, with rockier, river-ridden land to the north, dense forests to the west, oceans to the east, and great lakes to the south. Contained by mountainous borders all round, except east. The mountains west are insurmountable. Sort of a jack-of-all-trades scenario when it comes to trading, though their trades are very event-based ( refer to past headcanons on ‘blooming seasons’, as well as rare creature hunting & ceremony ).

TELMAR: Coastal, east of Calormen ( city ). The smallest city in the mainland, the coast dotted with caves, and surrounded by lush plant life and a steady line of trees. Fishing and textiles are their main trade. Their city is built into sheer white cliff faces. Known to work in-lieu with the Merfolk kingdom, which is North-East of their coastline, especially in fishing works and trading. Very independent before their collapse due to the famine ( headcanon referring to that previously stated but will be expanded upon ).
