[Tutorial] : How to Use ChatGPT to Create Lore #13: Developing Fantasy Economies and Trade Networks

A well-designed economy can bring immense depth and realism to your fantasy world, influencing everything from social structures to political power.

Whether your world’s economy is based on magic, agriculture, or valuable resources, ChatGPT can help you craft detailed and engaging trade systems, resource distributions, and market dynamics.

This guide will take you step-by-step through creating a functional and immersive economy, complete with examples of resource-based economies, trade routes, and economic interactions.

Step 1: Define the Core Resources and Economy Types

The foundation of any economy is its resources. Consider what your world has in abundance—precious minerals, rare spices, magical components, or agricultural products. These resources will shape the economic relationships between different regions and factions.

Example Prompt for ChatGPT:
“Describe an economy based on the mining of magical crystals in a mountainous region. Include the key resources, industries, and the impact on local culture.”

AI’s Reply (Simplified):
The Crystal Highlands are rich in Aether Crystals, a magical resource prized for their ability to amplify arcane spells. The economy revolves around mining, refining, and trading these crystals. Mining guilds control the extraction of the crystals, while specialized craftsmen are responsible for cutting and enhancing their magical properties. The wealth from the Aether Crystals has brought prosperity to some, but also sharp class divisions, as only the wealthy elite can afford the refined crystals for personal use. The local culture reveres miners as heroes, but there is a growing movement among lower classes calling for more equitable distribution of wealth.

Step 2: Establish Trade Routes and Market Dynamics

Once you’ve identified the core resources, consider how goods move across the world. What trade routes connect key regions? How does the supply and demand of resources affect local markets, and what are the consequences of resource scarcity or abundance?

Example Prompt for ChatGPT:
“Design a trade route that connects the Crystal Highlands to a coastal port city. Describe the goods exchanged, the journey, and any hazards along the way.”

AI’s Reply (Simplified):
The Silver Crescent Trade Route connects the Crystal Highlands to the bustling port city of Evershore. The route is famous for its treacherous mountain passes and thick, snow-covered forests where Crystal Bandits lie in wait, hoping to steal the precious Aether Crystals. Traders from Evershore bring rare spices, exotic fabrics, and fine metals, which are exchanged for Aether Crystals, enchanted gemstones, and arcane artifacts. The journey is perilous, with frequent blizzards and rocky terrain, but the rewards are great. In Evershore, the Aether Crystals are refined and sold to mages across the continent, while coastal goods help fuel the local economy of the Highlands, bringing luxury items to an otherwise isolated region.

Step 3: Craft Economic Systems and Political Influence

Economies don’t exist in a vacuum. Consider how political systems influence the flow of trade and resources. Is there a central governing body that controls resources? Are certain trade routes monopolized by powerful factions, or are there free-market systems where competition thrives?

Example Prompt for ChatGPT:
“Describe the political and economic relationship between the Crystal Highlands and the coastal port city of Evershore. How does the local government control trade and resources?”

AI’s Reply (Simplified):
The Crystal Highlands are governed by the Miner’s Coalition, a council of powerful mining guilds and wealthy landowners who control the Aether Crystal trade. They impose heavy tariffs on traders passing through the region and dictate the price of the crystals based on supply and demand. In contrast, Evershore is a democratic city-state where trade laws are more relaxed, and markets are mostly free from governmental interference. However, the city’s economy is heavily dependent on the Crystal Highlands, and many of Evershore’s council members are secretly in the pocket of the Miner’s Coalition. This creates a power imbalance—while Evershore thrives, the Highlands’ people remain trapped in a cycle of exploitation, with miners working long hours for minimal pay. Tensions are growing, as some in Evershore want to negotiate a fairer agreement, while others push for complete control of the trade.

Step 4: Create a Currency System and Wealth Distribution

No economy is complete without a currency system. Whether your world uses gold coins, magical tokens, or barter systems, it’s important to define how wealth circulates. Consider how wealth is distributed—who controls the money, and who has the power to influence the economy?

Example Prompt for ChatGPT:
“Design a currency system for a trade-based economy where Aether Crystals are used as currency in the Crystal Highlands. Include different denominations and their practical uses.”

AI’s Reply (Simplified):
In the Crystal Highlands, Aether Crystals themselves serve as the primary currency, though they are refined and cut into various denominations based on their magical potency. The smallest unit, called a Shard, is the size of a fingernail and used for everyday transactions such as food, housing, and clothing. The next level is the Facet, a larger crystal used to purchase more expensive goods and services, like tools and labor. The most valuable unit, the Core, is reserved for major transactions, such as buying land, paying for mercenary contracts, or trading with other nations. These denominations are carefully controlled by the Miner’s Coalition, which holds the largest stockpiles of raw and refined Aether Crystals. This control over currency gives the Coalition significant political power, allowing them to dictate prices and influence local markets.

Step 5: Incorporate Economic Fluctuations and Crises

No economy is static. Resource shortages, economic bubbles, or even magical disasters can throw your world’s economy into chaos. Consider how events in your world, such as wars, natural disasters, or the sudden discovery of new resources, affect the economy.

Example Prompt for ChatGPT:
“Describe an economic crisis in the Crystal Highlands caused by a magical disaster that disrupts the mining of Aether Crystals.”

AI’s Reply (Simplified):
A devastating magical disaster struck the Crystal Highlands when an ancient Leyline deep within the mines was accidentally ruptured during a mining operation.The rupture caused a Mana Surge, which rendered large sections of the Aether Crystals unstable and unusable. The Mana Surge also distorted the local magical fields, making it nearly impossible to safely mine new crystals. The sudden scarcity of Aether Crystals sent shockwaves through the economy, with prices skyrocketing as demand far exceeded supply. Many miners were left unemployed, and the Miner’s Coalition found itself at odds with the local government, which was under pressure to address the crisis. To make matters worse, the once-abundant mining town of Eldermount has now become a ghost town, with most of its population fleeing the region in search of work elsewhere. The crisis has led to growing unrest, with some calling for reforms to redistribute resources more evenly, while others blame the Coalition for the disaster and demand action against those responsible.

Step 6: Explore Trade Disputes and Economic Rivalries

Trade networks often lead to rivalries and disputes, whether over territorial control, market share, or access to rare goods. These tensions can create opportunities for intrigue, espionage, or even open conflict.

Example Prompt for ChatGPT:
“Describe an economic rivalry between the Crystal Highlands and a neighboring desert kingdom. Focus on the control of rare resources and trade routes.”

AI’s Reply (Simplified):
The Crystal Highlands’ monopoly on Aether Crystals has long been challenged by the Siroccans, a desert kingdom rich in Sunstone, a rare mineral that can store magical energy and is used in the construction of powerful artifacts. For years, the two nations have fought for control of the Desert Winds Trade Route, which runs through the Barren Flats, a stretch of harsh desert terrain. The Siroccans argue that they should be able to trade their Sunstone freely without interference from the Highlands, while the Miner’s Coalition seeks to impose tariffs on all goods passing through their territory. This economic rivalry has led to covert sabotage of caravans, espionage, and even military skirmishes along the borders. Both sides are determined to control the flow of these valuable resources, and tensions continue to simmer, with a full-scale trade war on the horizon.
