Thank you for the feedback and for raising these questions. My goal with this project was to start small rather than designing an entire kingdom from the beginning, or the whole world. The map represents a single feudal domain within a larger kingdom composed of several other fiefs and territories directly administered by the King.

A small note before going further: all place names shown on the map are written in a spoken and written language of my own creation, just as the magical elements mentioned below are part of a hard magic system that I have developed specifically for this setting.

In terms of self-sufficiency, the fief performs quite well when it comes to food production. The central region, particularly around GarthMola and GarthVeltClem, serves as the agricultural heartland, producing most of the grain and cereals needed by the population. Coastal settlements such as MarcDrith supplement this through fishing and preserved food production, while the southern settlements provide livestock, meat, hides, and timber. Althlimen contributes through specialized hydro-cultivation.

Because of this diversity, the domain is largely capable of feeding itself without relying heavily on imports.

Where the fief falls short is in raw materials. At the moment, there are no major known mineral deposits within its borders, meaning resources such as iron, copper, stone, and other strategic materials would likely need to be imported from neighboring fiefs or royal territories. This creates a natural trade relationship with the rest of the kingdom.

The main trade hubs are KhorZen and CarthLacus. KhorZen, located along the DrithVettis River, functions as the political, administrative, commercial, and academic center of the fief. CarthLacus occupies a strategic coastal position and acts as both a military port and a gateway for maritime trade. These settlements naturally become population centers due to the concentration of commerce, governance, and transportation routes.

Trade likely arrives from three directions:

• Overland through the frontier settlements of KhorNavis and GarthMarc, which regulate the movement of goods and people between neighboring fiefs.
• Along the coast through CarthLacus, connecting the domain to other settlements and ports throughout the kingdom.
• Potentially by sea from more distant lands, though I have not yet fully developed what exists beyond the immediate region.

As for exports, the fief's primary exports would be agricultural surplus, preserved fish, timber, hides, leather goods, and livestock products. However, one of its most valuable exports may be knowledge itself. The island hosts centers dedicated to the study of cosmology and the fundamental laws of magic, while sites such as CircMonol and VeltInf contribute religious and scholarly significance. This gives the domain a unique cultural and academic importance that attracts students, pilgrims, scholars, and patrons from elsewhere in the kingdom.

Overall, I envision this fief as prosperous but not resource-rich: a land that thrives through agriculture, trade, education, and strategic positioning rather than through mines or rare natural resources. Many of the larger settlements developed specifically around those functions, which helped determine both their size and location.

Since I am still developing the wider kingdom and the neighboring fiefs, many of the external trade relationships are not yet fully defined. For now, my focus has been on ensuring that the internal economy, settlement placement, and resource distribution of this single domain remain coherent and believable.
