The Returning Gem has three parts. Through the large grilled window, one can see a variety of goods in the main shop. By the door, there is a counter where the clerk will take sales and answer questions. (There is a loaded crossbow under said counter). It is an diverse mix of goods. The source of these good is found in the cages, along the right wall of the main shop.
In the Cages, the proprietor Craigius Salescrafter, sits and surveys his domain. Here he will loan money to those who want it. He takes their items as collateral. If they default on the loan (do not repay it in 36 days), he will then sell said goods. The amount of the loan is based upon 40-50% of the worth of said item. The item is then sold in the store for approximately the item’s worth. Some people do not take the loan chit, only wishing to unload merchandise.
Cragius will not deal with those he thinks stole said merchandise. He is a shrewd judge of character. Occasionally he will "set up" amateur and foreign thieves for the Guard, when they try to pawn more things.
In The Back is where the "exceptional merchandise" is displayed, items of great worth or historical significance. You can only be invited "in back" if they believe you have both the inclination to buy and the money. For certain items, he will hold auctions in back for a handful of buyers.
