The Dink Network

Update: I'm still stuck in the Goblin caves after three more hours of trying to get through them. I exited (not on purpose) and decided to return to the VB. I killed the slayer in the house with the corpse and the two guards in the building where you enter the mine. The guard in the next room won't let me in and I've talked to every villager repeatedly, but nobody tells me how to get into the mine. What am I missing? I also bought the half scroll and don't know the significance of that.
