Pawnbrokers

Pawnbrokers exist in all periods of the Pendragon campaign. Pawnbrokers can be found in any city. The biggest advantage is that they will accept almost any item of value (but not livestock other than horses), and the knight can get his goods back afterwards.
In pawning, the knight offers some valuable possession, and the broker names the amount he will loan on it—usually about half the normal purchase price. Sentimentality is worthless, so pleas of family heirlooms and the like fall upon deaf ears. A time limit for the loan is set (typically one year), and a brokerage fee (minimum of 10%). If an agreement is reached, the knight gives his possession to the pawnbroker, who gives him the money and a receipt for the goods.
The knight must repay the loan and the fee within the time limit. The item is safe for the period of the loan. If the limit,he gets his possession back. If not, he forfeits it; the item now belongs to the broker, who may sell it (for 75-100% of its normal cost). If the knight acquires enough money after the time period elapsed,asking price, if they are still available. To see if a pawned item was sold, roll d20: a roll of 01-10 indicates it was sold to someone else and is lost.
