Don't worry. Just people making stuff up about some half arsed dlc dreams...

Then How about This:
If you take to heart on What Bethesda said: pay attention to the games events, it seems the most likely option is that the Dovahkiin will have to re-light the dragon fires in the imperial city. The Aldmeri High Council is trying to destroy each of the 8 towers that dot Tamriel's landscape, the only two that remain, the Snow Tower and the Bronze Tower(Dwemer Owned), but that was lost in time with the Dwemer. If you take it by its literal name: Snow Tower; you would say High Hrothgar...but according to Dwemer texts, there is a second Blackreach underneath the southern portion of Skyrim that runs under The Throat of the World. The texts also explain that there are two entrances two this second Blackreach, one lost in Blackreach itself, and the other in the Dwemer city of Markarth.
Thus is why you find Thalmoor in this city and none other. Since the signing of The White-Gold Concordiate the Thalmoor can move freely in Skyrim...relatively free at least. If the Thalmoor succeed in destroying the Snow Tower, which for the sake of story that will probably happen, the Dovahkiin will be forced to relight the dragon fires with the Amulet of Lings. Lore suggests that when all 8 towers cease to work, reality will unfold on itself and chaos will reign and thus bring about the World Eaters return. This will force the Psijic Order to intervene and stop time and tell you to relight the dragon fires.
With some speculation, we can assume that if using an Elder Scroll creates a time wound, it is likely that there are many wounds that have been created over the years. When Martin shattered the amulet of kings and brought down the powers of Akatosh, Akatosh uses the power of time as his main entity. If shattering the amulet of kings brings forth Akatosh, Then it can be assumed that the shards are cast through the open time wounds, Then the Dovahkiin would have to travel through time with the help of the Psijic Order, who are known to be able to control time. Once the shards are reunited the Dovahkiin would then be able to light the fires, but probably not before having a final showdown with Alduin and then the Aldmeri High Council Leader after the Dragon Fires have been lit.
