I'm going to be starting up a Razor Coast game tomorrow with 4 players, and I don't want to just drop them all off in Port Shaw and say "Alright guys, go nuts." This approach has been historically bad with this group, so I want a short preliminary adventure to get the party together, and maybe introduce them to some of the factions they are going to meet once they arrive in the city.
I'm moving Port Shaw to Golarion, and saying it's a former holding of Cheliax on the far side of the Eye of Abendego. PCs are all passengers aboard a merchant ship that stopped and took on a few passengers in Magnimar, Westcrown and Absalom, and now is on the way back. Noteworthy crew and passengers on the ship include a half-Tullita sorcerer who handles the ship's arcane needs, a few dragoons guarding a mysterious shipment (no clue what it is), and Shakes Montgomery, who is earning some extra coin as a laborer on this voyage.
So I got a setup, but I'm not sure where to go from here. Does anyone have any suggestions on a short prelude adventure, preferably one that makes sure they will not be leaving the port again on this same ship?
