So Westcrown is in an area of Cheliax where halflings are considered 'perfect height for kicking in the head.' (It isn't Kintargo, otherwise why have the whole attitude in the first place?) So while a halfling PC can get by with staying out of sight/posing as a servant, I see problems arising in the last part where the party needs to address Thrune backed troops. One doens't become a high ranking Thrune officer by being a Slip lover and one of them speaking up would at least get a 'Control your slip.' from the officer. So, how would they be able to contribute or is it best that they stay out of it?
