You see, Elder Scrolls are quite literally the biggest deus ex machina you'll find in all Tamrielic lore. One was used in Oblivion, which I thought was odd since it was only used to relatively minor effect. Skyrim features one too, but to much greater and interesting effect.
The fact that gamesas has pointed out straight from this first Dawnguard trailer that this DLC will feature an Elder Scroll *probably* vouches for it being a major plot element. So overuse & deus ex machina are the keywords here.
Are you tired? Can't concentrate? Having trouble sleeping over that:
- Nasty dragon?
- Depressed Gray Fox?
- Annoying fan?
- Leaky roof?
- Indigestion?
