From Fallen London Wiki


The most important thing to know up-front is that you cannot save Rat-Shillings. All shillings must be spent before you exit the Rat-Market. If you are purchasing a large item, take extra care that you have enough items to trade in before starting to exchange. If you need to procure more items for shillings, you must leave the market, giving up all the shillings you may have already traded in.

The second-most important thing to know about is The Rat Market (Bazaar). In some cases, this may be the purpose of your visit. In other cases, you will not be able to leave until you visit it. You are locked in the Rat Market until you spend all your shillings, and in some cases the Shop may be the only way to use up small amounts of spare change.

World Qualities[edit]

What can be sold for Rat-Shillings, and what can be bought with Rat-Shillings, changes with a variety of different World Qualities on a weekly basis in a way that is not yet apparent. The Rat Season determines which items you can sell for Rat-Shillings. The Rat-Wind and Rat-Moon each unlock an array of items to buy, and their conjunction unlocks a Most Valuable or otherwise hard-to-get items. These are not regular economic items, and are either at a more substantial discount or are otherwise difficult to obtain. The False-Season also serves to unlock a unique piece of buyable equipment, and unlike other World Qualities its progression is known and consistent: it follows the real-world season and rotates through four values of the course of the year.

The Goods[edit]

Selling Items for Rat-Shillings[edit]

What items you can sell for Rat-Shillings depends on The Rat Season: World Quality. As of now, all items are available in a range of values for this quality. This makes for somewhat less volatility for players wishing to stock up on exchangeable items.

By all indications, the option to sell a Fourth-City Echo is always available. This item has no other repeatable uses at this moment, and can be farmed in L.B. Industries at a competitive rate. The other options are not as easy to obtain efficiently, except for players with an advantage for obtaining Cartographer's Hoards.

Buying Items with Rat-Shillings[edit]

Items can be purchased with Rat-Shillings from two shops in the Bazaar tab, or two storylets which do not cost actions. A single Rat-Shilling is assumed to have a value of ten pennies ( 0.10). The actual exchange rate varies by good, but that's an easy value by which to compare.

In the Bazaar tab, cheap economic items can be purchased for a value equal to their Bazaar sell price, while more expensive items have a mark-up, going up to a 100% cost increase for items selling for 2.50 or more. Equipable items can be purchased from the Rat Market for slightly cheaper than they cost in the Echo Bazaar (which is always still greater than the value of selling them back to the Bazaar).
