The Elder Scrolls VI. ГДЕ???

Was there anything like that in Skyrim?

To be honest, the hints were subtle, and it was easy to miss them. Of the obvious hints about add-ons/DLCs/sequels, I only remember what Tullius said. He spoke of the danger from the Aldmeri Dominion and the possibility of war with them. So, I would expect the events of the add-on to take place in the lands of the Altmer, Khajiit, and Bosmer.
