What can players actually buy and sell in a fantasy settlement?

The universal shop breaks belief on arrival

Most settlements sell from the same invisible stock: whatever the party wants is either on the shelf at list price or it is not, and selling works the same way in reverse. A hamlet buys a dragon hoard without blinking, a mining camp stocks plate armour in six sizes, and nobody ever needs to wait, travel, or ask permission. The economy answers built earlier in this cluster stop mattering the moment the party opens a purse.

The repair is a profile, not an inventory. Six short lines per settlement decide what is routinely about, what arrives sometimes, what must be made to order, and who can actually pay for what the party carries in. Written once, the profile answers every buy and sell question for sessions without a single exhaustive list.

Six lines of a market profile

Draft these when the party first heads somewhere, starting from the settlement ledger this cluster already built:

• Scale Place the market on a rough ladder: hamlet, town, regional centre, major city, trade hub. Scale governs breadth and buyer depth together. A hamlet feeds its own; a regional centre gathers the surplus of a dozen villages; only a city or port holds enough coin and craft in one place to move the exceptional. Keep the ladder loose: it guides judgement, never acts as a locked gate.
• Common goods Name what residents routinely produce, stock, or use: grain, livestock, timber, basic tools, ordinary cloth. These are easy to find in ordinary quantities at steady prices, and they stay steady unless a pressure from the scarcity answer bends them. If the party wants rope, nails, bread, or a mule, this line ends the discussion.
• Imported and irregular goods Name what arrives through caravans, ships, seasonal fairs, or travelling merchants: salt, iron, wine, lamp oil, decent steel. Such goods may be present but never reliably, so answer with timing rather than price: the caravan is due, the fair ended last week, one merchant has three barrels left. Absence here is ordinary, not a crisis.
• Specialists and commissions Name who can make what cannot be bought off a shelf: the armourer, the apothecary, the shipwright, the scribe, the alchemist, the enchanter where the setting allows one. Each entry needs its terms: unusual materials, time, advance payment, and any guild or political permission. Fine weapons, plate, and extraordinary items live here or nowhere; there are no magic shops unless the settlement's institutions explain who stocks them and why.
• Buyer capacity Name who can actually pay, separately for three kinds of sale. Ordinary valuables go to any resident merchant. Bulk cargo needs a merchant house, a guild factor, or a noble provisioning a household. Rare, prestigious, or magical pieces need a patron, a temple treasury, a fence with distant contacts, an auction, or a journey to a larger market. A town can overflow with bread and still have nobody able to buy a legendary jewel, and that gap is a feature.
• Current pressure Note the one strain bending the profile right now, borrowed from the scarcity and trade-route answers: a closed pass, a late caravan, a festival, a levy, a new route. Pressure moves goods between lines: salt slides from imported to scarce, wool collapses from export to unsellable, commissions stall for lack of materials. Update one line when the world changes and the market stays honest.

Six lines fit on an index card. Anything the party asks maps to exactly one of them, which is what keeps rulings fast and consistent across sessions.

Two distinctions that prevent most arguments

First, availability is not affordability. A breastplate can hang in the city armoury at a price no starting purse can meet; a healing draught can be cheap in the capital and absent in the village at any price; a commission can be agreed today and delivered after six weeks of waiting. Say which of the three blocks the purchase: too dear, not here, or not yet. Players accept all three when the reason is visible, and dispute all three when it is not.

Second, the daily market is not the specialist market. A settlement can feed and clothe everyone in it while supporting none of the following: arms in bulk, luxuries, magical services, high-value treasure purchases, or large cargo deals. Never reduce a market to one number. A big prosperous town can still send the party to the city for plate, to the port for a buyer, and to a named broker for anything enchanted.

Before the party reaches the market

For each settlement on the route, confirm:

• Can you place its scale on the ladder in one phrase?
• Are common goods listed narrowly enough that most requests end quickly?
• Do imports carry timing (due, just missed, last barrels) rather than flat refusals?
• Does every specialist have terms: materials, time, payment, and permission?
• Do you know who buys ordinary loot, who buys bulk, and who buys the exceptional, by name or office?
• Is the current pressure written as moved lines, not as a mood?
