Any idea how I get out? I rescued the one dude and kill the giant monster grub but cannot figure out how to leave. 

If the guards couldn't be convinced to leave the lift down for you beyond half a day, exit through the south chambers in the Old City Ruins (there's a way to open that sealed door from the inside)

Can you avoid fighting pirates who guard the lift from this point? seems like they are scripted to aggro if you pass certain line. i dont really want that nasty -3 reputation there.
