If you haven't seen this yet, check out Enderal. It's not released yet.
Info- It's a successor to Nehrim, a mod for Oblivion that has recieved a lot of praise. As it is a complete overhaul, you'll notice very different mechanics than regular skyrim, and it appears to me you won't be able to travel there from your other saves. The mod is german but will be translated in English.
Sadly I have lost all desire to play Skyrim because its color scheme is so bland and the combat feels too clunky for me. I literally get headaches from playing Skyrim for too long, and I don't get that with other games that don't mask the whole screen brown/grey. Unless this mod revamps the color masking and combat, I won't be playing it.
