Thinking I would play an Alchemist from northern Brevoy. Setta would have spent her young adult days among the pirates of the Lake of Mist and Vales and Sellen River. After some particularly egregious criminal activity she up and ran south, her former "friends" hot on her heels. The river kingdoms seem the perfect place to lay low and start a new life. While Setta is a bit too soft hearted for a life of rapine and violence as a river bandit, her time in that rough and tumble world has left her with a rather grey and "ends justify the means" world view which I think would predispose her towards the Spy Master role.
I will wait on crunch and a full backstory while I see what other people are thinking of playing to make sure this would fit in with the party!
