So we know that in the upcoming expansion/DLC, Dawnguard, there will be a choice between two groups: The Dawnguard, and the Vampires, where you side with and do quests for one or the other. We also know that the vampire's eventual goal is to unleash some sort of magic, or cataclysm which destroys/blocks the sun for forever, making it so vampires never have to fear the sun. Now I assume that if you side with the vampires, you will help them succeed in blocking out the sun. Will this mean that from then on, will it always be night-time on that character?
First, just think of the environmental concerns. No sun means no crops, which also means the world's food supply is dramatically cut. There is no photosynthesis, how will the trees survive, and then conversely how will humans survive without something to filter carbon dioxide into oxygen? I guess Bethesda will kind of say that Earth physics/realities don't necessarily apply to Nirn, but it will seem really odd if it's constantly night time and I see farmers ploughing their fields, with crops growing.
Secondly, and more importantly, is Bethesda really prepared to fully support game-world changes that would assuredly occur as a result of the world being plunged into an unending night? For one, random NPC's forgetting about the Civil War, their usual dialogue, and everything else they talk about and saying 'Oh wow, the sun went out...' rather than pretending it didn't happen? What about vampire attacks, populations becoming afraid of a 'vampiric rising' that comes about as a result of no sun? Will we see more vampire NPCs? Quests, or even political leaders forgetting their priorities and saying 'oh crap, we need to figure out how to turn the sun back on!'? If you're like me, then you have a big, fat 'I doubt it', and expect the world to progress completely, 100% as it was before the Dawnguard DLC, just with crossbows, mounted combat, and a darker shade to everything on account of the everlasting nighttime. And that would be quite a shame.
