Deep inside the caves, protected by towns of dwarves : a fortress.
The entrance is an elevator going even deeper inside the caves.
Are you going to take the cage? You should hurry because you start to hear ward drums.
During the way down, you can see enormous pillars and a sea of lava. Only some islands disconnected.
Perhaps you'll know more about this once you're on the ground. One unique thing is focusing your attention; a big carved stone in a form of a gigantic dwarf.
During your way down, you saw a bunch of things like breweries, forges, armory and even some sleeping beds.
There was a big market place with traders but it was too far to see what they were selling.
You saw Dwarves, no doubt about that... But what could be there?
