my stalker has gone straight from the circus tent to umar hills with aerie and jan as it sounded like the sort of thing he should be getting involved in

i've taken the job and travelled somewhere else (great area by the way) and have recruited my 4th (and final) party member
i'm quite happy sneaking about here but my party is feeling a little bit out of their depth and at some point i can see i might want to head back to the city to re-equip, learn some lessons, so my question is - am i on a timer? (especially stronghold-wise)
thanks
