A small crowd would be gathered in front of an auctioneer..
"The auction will start at a 175 minas, the highest bid will win the strong reddish scales from a young wyvern. They can be used to forge armor and many other valuable thing!" The tall auctioneer would state looking around the crowd " Hey you!" He'd point his finger out pointing at you " What is your bid?"
