What are these places, how do them look like?

In Vvardenfell, there are three region I wanted to explore but; biten by slaughterfishes. I wonder what is there. Can any ZOS employee tell us? Because; I really wonder.

Is there a possible way for us to see those places with techniques like data mining etc.

Top is sheogorad which is inaccessible. Middle is red mountain which is also inaccessible. Bottom left is firemoth island, which was the tutorial for people who had morrowind as their most recent chapter purchased before it was replaced. Firemoth island is also visited during the Seyda Neen quest if you didnt do the mutually exclusive Firemoth tutorial.

There is not much in Sheogorad, just a cranky old lich with a goblet the thieves guild wants. You can sneak it out without a fight at a very low level if you get your hands on a telekenisis spell. As for Red Mountain, it's mostly lava, and some real ugly looking corrupted blighted creatures that used to be human. Oh and you don't want to go to Firemoth Keep, it's run down and full of undead.

Although Dagon Fel is a pretty little fishing village well worth a visit. If you want to see them, just google TES3: Morrowind.
