My (Rough) Theory for DLC: Dawnguard
Seeing that the world was supposed to end with Alduin destroying everything (sort of, since Alduin’s Wall foresees the Dovahkiin, although Alduin is still at the end of the prophecy regardless) the world is pretty much… lost at this point. Unless another prophecy comes up, everybody is freewheeling through Mundus without a prophecy to guide major events. Since every Elder Scrolls game has been leading up to this prophecy, and now that the big prophecy is finished, I think Dawnguard might be set in Hammerfell. Here is my rationale.
Whenever the mention of “dawn” comes up, it is usually referring to the very early time, or the Mythic Era. The oldest structure in Tamriel is purported to be the Adamantine Tower on the Isle of Balferia in the Iliac Bay near Hammerfell, dated back to that era. That tower is the closest thing to the “dawn” as you can get in Tamriel. Plus, we’ve already seen in Skyrim that there is a high amount of reference to Hammerfell already. The quest with the Redguard Maiden, the fact that there is already a preexisting “Redguard Outfit” when no other race gets that privilege, and the inclusion of curved swords (CURVED SWORDS) all show an odd, unexplained favoritism towards Hammerfell.
Then there’s the lore aspect, because the Adamantine Tower is where the gods converged to discuss the creation of Mundus. We’re already dealing on an epic scale with Skyrim, and we’ve interacted with Akatosh in Oblivion; I don’t see why a more divine storyline couldn’t be in the works. Plus, Adamantine Tower is where the gods cast Lorkhan’s Heart from, the very same heart that is discussed in the quest “Discerning the Transmundane.” That might just be the Devs wanting you to be familiar with the concept of the Heart, especially since the game forces you into that Daedric Quest on the course of the Main Quest.
There's also the theory that the Mythic Dawn may be featured again. Originally I thought the idea of the Mythic Dawn involvement to be silly; the game already addresses the cult in a Daedric Quest, and that’s the end of it. But the more I think about it, Dawnguard may actually tie in. If the Heart of Lorkhan really is a plot device in this new DLC, then the Mythic Dawn would tie in perfectly due to their desire to restore Tamriel to its “rightful owner,” Lorkhan. Not sure how that could play into a storyline yet, but it is definitely a possibility.
So let’s play around with this idea, guys! What do you think? Reasonable? Any ideas for a potential storyline taking place around this? Discuss at will, friends.
....they want mehrunes dagon to have the world, they just ignore lorkhan...
