Marketkeeper

The Market keeper
There are all kinds of NPC's which are an active part of the game. one of the most important NPC's should be the market keeper. The market keeper is one of the few NPC's you will find in every city or town. Beside for capital cities in what you will find market keeper assistants as well, probably due to the size of the cities, so u don't always have to go all the way to the market in order to sell and buy your goods to the market.

What do they do?
They are the main NPC to sell and buy trade goods. Especially those with a merchant job rely on the functionality of the market keeper.

Basically once you click on the market keeper the following options will appear:
 * 1) Buy goods

By clicking on it you will be able to get an overview of all trade goods the market keeper has to offer. The assortment will be different in every port. Also the quantity as well as the assortment may improve due to town investments, fame, job and so on... Make sure to buy profitable goods. The lower the market rates are (under or near 100%), the most ideal to buy them. They will be more profitable when selling in other towns.
 * 1) Sell goods

Here you can sell goods which you have on you (cargo). Make sure not to sell goods which aren't giving any profit. Non-profitable goods will appear with a red pricing. Don't sell these, you will loose money on them. However might give a profit in a different town. In both of the above options you will have the ability to haggle about the price for either buying or selling your trade goods. I suggest you don't use it if you are grinding for experience instead of Ducat profit. After all, it will only improve your profit once it was successful, though there is a chance is fails and that will make it unable to haggle any further. Once the haggling failed the profit you had haggled before will be reset.

With the right job as a trader some more options will become available when talking to a market keeper such as the ability to consult the market rates for any trade item. See the profit you would get when you sell it in a nearby town etc.

Requirements
Market keepers are accessible to all players even explorers and maritime players. However they will only be limited in their abilities.

Also depending the town you are in different fame, disguise and / or port permits will be needed. As I mentioned before, the amount of investments made in a town will not only affect on your fame, but just like more tools at a craft-shop, items at an item shop, scrolls, ship-parts, books,... they might unlock more and different trade goods at a market keeper in certain towns as well.
