I think you were aiming for the D2:ED
Help/Tips/Tricks forum...
In the bunker where you released the woman from the cage, there are 3 levers upstairs (with the 2 merchants) that you can throw to disable the anti-dragon shields and the barrier blocking access to the rest of the fjords.
There is a cave above the waterfall (there are 2 generators there you need to disable, but make sure you clear all three areas accessed by teleporters before taking on the main bad guy, or one of the rooms will remain sealed).
In the mine, if you found the pedestals with the books, and the ones you need to move the books to (pay attention to the candle holders beside each), then you have pretty much cleared it. Actually, more important than that are the 2 malachite ore veins, beside where you get the books (save before running your crosshairs over them, so you can reload until you get at least one malachite gem; 2 gems are not that hard to get, 3 are possible if you are lucky or patient, and 4 are rare).
Welcome to the forum.
