ok. for FP to Q betrayal, you need to find a "squire". there is one in SFP who wanders at the base of the curved stairs (basically, along the same path as Sergeant Nominus (sp?)), and another in EFP in the inn (a kerra tucked back in a corner), and another in WFP (a ratonga in the Blood Haze Inn, in the room to the right when you enter).
Talk to them, and they will start you on the path towards Qeynos.
Hope this help
