You're in Act II then, right?
If I can remember-HA..you head out of the bridge area after you make friends with Finala..(SP is horrible for that, but hope you know who I mean)
then you'll find the caravan following that 'pathway'..
She's a good one to add to your party, she fixes things..remember the one location where the handle was broken in the cave and it said..if you had someone like Finala she could repair it? Anyway, she's also a Combat Mage..so she comes with some good spells and can be of value for quite a bit.
