Why not making a DLC featuring the dragon Skakmat from Daggerfall? A piece of High Rock, the Wrothgarian Mountains, could become avaliable to explore, and there could be a story about that dragon and maybe add some new castles like Shedungent.

Thoughts? Oh, and I never played Daggerfall so I don't know much about what happens in the game. I just read on UESP and found this dragon out, then the idea came up.

Edit: And why not? Even the dragon from Redguard, Nafaalilargus, plus a piece of Hammerfell. Meh, one can dream.

If anything, I want atmora as a DLC, it's a big part of skyrim lore, and how it came to be.

But Atmora is inhospitable.

Some references to http://www.uesp.net/wiki/Lore:Nafaalilargus would be cool, too. There's the mention of "Nahfahlaar" in Atlas of Dragons, but it's pretty ambiguous as to whether or not they're the same dragon.

EDIT:

Ninja'd by an edit. XD

DLC typically adds new themes to the game, not continues the old one.
