Town Information

Moriarty's intention is to make himself richer by using Greyditch as an outpost to hijack passing caravans -- ALL types of caravans. This includes, goods, tech, food, weapons, and slaves, such that he can re-sell them to where they are meant to be delivered (as though Moriarty has rescued the caravans from some other pirates), or, to make money on their escort (in the case of slaves)...

Regarding the "faction", it is a bit of a spoiler, but: those that are coming to the town in response to the flyer, and the rare case of Celeste, are totally oblivious to the town's true purpose and are in the Greyditch faction. Only Joe, Harold, and Celeste (through blind loyalty) are part of the Moriarty faction. Eventually it will start to become evident that the town isn't making money in a legitimate trading-based economy, and there will be a blow up...with the factions fighting against each other. As long as it is IC, and reasonable, your character MAY change faction later in the game.
