The island is supposed to give off a feel of isolation and despair after the Red Mountains eruption years before.
Raven Rock is easily the nicest, and possibly safest(second to the Skaal Village) place on the island. Because some of us Morrowind players recognise and feel safer around the Redoran guard - I'm no exception.
The icy northern reaches keep isolation in mind but with a more familiar approach, Frost Trolls and Draugr.
Dwarven ruins have been really steeped up, and they work in a more puzzle oriented way.
Lastly the island has some great stuff on it, Bloodskaal Blade for example.
But am I scared by it? Not anymore - Serana has my back. Plus I'm level 34 with a 128 damage dealing Ebony Battleaxe. What could go wrong?
