Nix showed up at the hidden valley and the group had to hurry to a nearby valley and aid some of her people that had been attacked. They killed most of the attackers but a fleeing drow set of some kind of earthquake affect that opened up a spreading fisher in the valley under the group and they had to scramble to not fall into the fisher. Many of the bandits were swallowed into the fisher. The group made their way back to the hidden valley and found that Soram had arrived. He showed them a secret entrance into the caves they had stayed in and they used the underground old dwarven highway to get to the rebels current mining camp.
Blackstone Mine is an ancient mine once run by a famous dwarven miner named Corage. The dwarves have long since left this mine and it is in disrepair but still shows the strength the dwarves had for mining.
