Sounds about as forward thinking as most politicians I know.

Just going to point out that the sun in the elder scrolls universe isn't a ball of plasma and is infact a big ass hole in the fabric of reality from when Magnus pussies out of creation. So it is entirely possible that plants could grow without sunlight in the elder scrolls.

Also for any more specialized lore junkies are vampires hurt by the raw Magicka from the sun or is it more of a raw lumens thing?

Also also the Empire had a space program, do with that what you will.

Let's assume this is correct about surface plants needing the raw Magicka from the sun to live.

Blackreach is full of plants, many of which are edible, and receives no sunlight. Humanoids could just start farming the plants from Blackreach along with fungi. That should be enough to sustain a large enough population for Harkon and his court to feed on in their vampire paradise.

I mean a billionaire would literally attempt this if you told him that he would be the number one billionaire if he blocks the sun out.

Is it the light or the UV rays that kill them, because if it's just the UV rays, we have technology that can block them now.

This is just a metaphor for capitalism. Capitalism will literally kill the earth and suck the population dry just so a few can enjoy their lives.

Meanwhile, in Legacy of Kain:

Vampires: Uh, boss? You corrupted the pillars of Nosgoth - which is great and all - but now the sun kinda/sorta doesn't work anymore. It's always dusk.

Kain: So what you're saying is that we vampires can move around freely. All the time. Excellent.

Vampires: Won't that eventually kill all the humans? Yanno, with no food and all?

Kain: ::shrugs:: Fuck 'em.

Same plothole as in the Matrix movies

I want to play a game one day where it has a character AI good enough to be able to point out something like that and have it affect the flow of that character's story.

"Oh hum.. you... make a good point. Ok, pivoting: let's block out the sun but only on Tuesdays and Thursdays!"

If you can prove skyrim's plants and animals need sun to survive then his plan is stupid. Otherwise, its magic and theres no sound logic to anything so it wasnt worth mentioning in a fantasy setting.

The falmore adapted to live without sun, humans would do the same.

Also magic might be able to produce UV rays to allow mages and farmers to still grow crops.

Falmer do just fine without sunlight

Yeah, I always found his plan stupid
