This device was developed by none other than Sam Dolucre, the Solarian merchant responsible for developing Dolucre Street in Mammon. Today, Dolucre Street is renowned as the universe's premier marketplace. It owes its success to a very simple strategy: allowing only two shops of a kind, placed across the street from each other. In order to replace one of these shops, a prospective businessman must be able to propose a model to sell equal or better quality goods at a reduced price. The margin of profit has become exceedingly low due to competition, but the flow of customers is such that the locations are highly coveted.
Dolucre has since become the richest man in the third ring, but his aesthetic is still Centrian. He has a smile like a cracked geode.
