I was reading about the previous TES games and noted that there are some pieces of lore that could be combined in a possible and intriguing DLC for Skyrim.
Since Skyrim is mostly about dragons, as most of its design shows that aspect, I thought it could be fitting to add some fragments of past lore that were about our friendly winged creatures.
First of all, there's http://www.uesp.net/wiki/Lore:Skakmat, a dragon featured in Daggerfall who is said to live in the Wrothgarian Mountains, High Rock. Up on the mountains, there is an enigmatic structure, http://www.uesp.net/wiki/Daggerfall:Shedungent, where a mad http://www.uesp.net/wiki/Lore:Nulfaga used to live. So the DLC could actually add these two things, a new story involving a dragon, a castle, and a new piece of land.
Finally, an other dragon featured in Redguard, http://www.uesp.net/wiki/Lore:Nafaalilargus, could be added to the DLC and make an even more complete combination of surprise and lore-explaining points. Maybe there could be an Island in Hammerfell that we would visit to meet the dragon and discover who knows what.
What do you think? Cool enough? Let me know.
