From publisher blurb: Terra Aveyon. A floating city built on archaic technology that has much to offer and even more to see. Explore the back alleys and access tubes that make up this Steampunk urban fantasy setting. Pipes & Pistons is a Backstory Cards Setting Grid to use during the Backstory Cards process. Taking turns going around the table, each player draws a Backstory Card and answers the prompt on the card, referring to the setting grid for random elements. Think of it like a dynamic campaign or one-shot outline. Terra Aveyon is a flying city, and in many ways, behaves as a nation all to itself. Wealthy traders politick and gamble as if they were gods, leathery pilots and their transient crews are in and out of the sky docks constantly, the Green Gloves somehow keep the place flying, while looking for a leg up by dabbling in something darker. It is a city full of mysteries, intrigue, and danger that will inevitably discover you, even if you don’t seek them out of your own accord.
