Well... those are interesting, for what we know they might be the product of an Elder Dragon (we still don't know the classic final boss).

Or maybe this area will be formed by 3 main "zones".

Probably the upper one would be the colder one with those crystals.

The one at the bottom would be the caverns with lava.

The one in the middle with just rocks... probably the ED will fight there.
