What it says on the tin, how can we get Poland to own Farther Pomerania with a point of divergence as late as possible but before 1618? I'm in the middle of trying to figure out a way to create a more powerful Poland with one idea being to give them a western border on the Oder by having Sigismund II Augustus turn down the idea of Joachim II being co-enfeoffed with the Duchy of Prussia so that it reverts to the Polish Crown in 1618 rather than entering a personal union with the Electorate of Brandenburg to form Brandenburg-Prussia, Farther Pomerania being the other major part needing to be dealt with. Any help people can give is gratefully appreciated, thanks.
