I hope it is about Azura and we get to travel to Moonshadow!

Moonshadow would be awesome. Although something about the Thalmor invasion or perhaps the Empire invading Summerset Isle would be even better.

Nah, it's too mundane and normal. Something supernatural and Daedric would be awesome.

Though yes, the Empire invading the Summerset Isles would be great.

I think the Summerset Isles are a bit too large for a DLC and perhaps only a future Elder Scrolls game would be able to do it justice. There's enough foreshadowing about the thalmor in Skyrim, who knows, maybe an all-out war between the elves and humans could be the focus of Elder Scrolls VI. I think the western part of Morrowind, particularly Blacklight would be the most 'logical' setting for a DLC. Look at http://i.imgur.com/s3mbz.jpg, it's a mock-up of what Blacklight could contain and it meshes very well with the setting of Skyrim (and even the road leading to Morrowind makes sense if the DLC is set there). Plus the 'Dawnguard' name somehow reminds me of Morrowind and Azura...

Posted this in an earlier thread:

Was this map drawn before or after Skirim came out? Because both roads from Skyrim to Morrowind are in the correct position. Is it from a MOD project?

After. It's http://www.reddit.com/r/skyrim/comments/nin7e/dlc_hopes_and_dreams_blacklight/ (r/skyrim) where an user created this image as a speculation for Skyrim's DLC. Back in February I think. I just thought about Blacklight as it 'fits' a lot into the idea of DLC...it borders Skyrim and has the perfect 'size' for a DLC. Since Shivering Isles had a strange, alien feel to it, going back to Morrowind's more alien landscape might be a possible direction for Skyrim's DLC.
