Well it's clear to me how skyrim will effect TES VI.
The Facts
The thalmor ARE NOT the aldmeri dominion. The thalmor are the rulers of the aldmeri dominion. Not everyone in the dominion is a thalmor. This is the purpose of the white gold concordant. If the empire refuses to sign a "PEACE" treaty it will appear to the citizens of the the dominion as if the empire wanted war. When the empire signed the concordant, the thalmor could no longer justify the war in the eyes of the citizens of the dominion. This is why they too wanted peace. if they continued the war they would have their own civil war on their hands. Remember unlike the empire which was formed by conquest, the aldmeri dominion was form by the wisdom of the thalmor. The people of Elswyre Valenwood and Alinor (the thalmor renamed the summerset ilses) put the the thalmor in charge.
The thalmor are the biggest threat in the elder scrolls EVER!!!.
The thalmor want to destroy humanity and become immortal. To do this they must: Destroy the towers (only 1 left), destroy the empire (pretty close if you ask me) remove talos from the pantheon of human religion (done) and kill all humans. With a goal like that, imo, they are worse then dragons.
The thalmor believe the aldmeri story of creation. Most people probably know the human story better then the aldmeri story.
Human version: The aedra were happy with the mortal plane even though they lost some of their power the ones that had no more power left became the first mortals to inhabit nirn, from whom all the mortal races come from.
Elven version: The divine were all tricked by lorkhan and they wanted revenge. They built the adamantine tower (aka ur-tower, aka direnni tower...Aka ada-mantia) to judge lorkhans action the completion of the tower was the end of the dawn era. after lorkhan was judged, auriel (akatosh) and trinumac (he later becomes malacath) left to go kill lorkhan who was at the throat of the world. they took with them the elves that became mortal. Lorkhan in order to combat this created humans to kill elves...... but they screwed up and lorkhan died anyway. humans fled to atamora lorkhan has cut in two and his heart was tied to an arrow and shot into what would later be the red mountain.
Don't think skyrim is simple. Skyrim is filled with tiny bits of information that when combined with all the information from other ES games and info you can get from the developers blogs you can see that it appears bethesda know exactally where this series is headed.
Enough about the thalmor for now what about skyrim's stuff.
Ulfric Stormcloak: he's not the great leader the stormcloaks say he is nor is he the horrible villain the imperial say he is. He was captured by the thalmor and... "conditioned"... to start the civil war. He is very much willing to die for his cause (just look as how he doesn't surrender even after wind helm is sacked and his army killed). on the other hand he DID murder high king torygg. He challenged the king knowing that he was gonna use the thu'um to kill and start a war. Even if it was a match he still knew the king wasn't going to kill him. Even from the sounds of it the king was a wimp anyway, some people said he probably would have caved if ulfric had said let's start a war. Other hand ulfric manged to inspire half of skyrim to fight for a just cause even when the empire wouldn't. still though, Ulfric seem kinda racist. He is destroying the way of life for the dark elves and and claiming it's for the nords. He also seems like he wants to be high king, other wise why would he need to kill torygg. I guess that's not really negative; it's not a crime for people to have personal ambitions.
The nords: They seem extremely racist... well at least the stormcloaks do. Seem almost like white supremacy. White supremacist are pro segregation, stormcloaks are pro segregation. White supremacist are racist, stormcloaks are racist. white supremacists hate to see other races in their cities, stormcloaks hate to see other races in their cities.
The dark brotherhood quest line has 2 ending. Yep, you heard right. you can either kill the emperor or destroy the dark brotherhood(by killing astrid). by the next tes game bethesda has to make both ending somewhat cannon. I can only think of one way.....
The solutions to multiple ending and plot holes:
The thalmor are the solution. by the next elder scrolls game the thalmor will be in control of skyrim and cyrodiil. Here's why:
Q: how can you make both sides of the skyrim civil war canon
A: Destroy the empire. If the empire falls to the thalmor the resolution of the skyrim civil war is void. If Ulfric won the war, the thalmor would kill him and take skyrim. If the empire won the war the thalmor would kill Tullius and still take skyrim
Q:how can you make both sides of the dark brotherhood quest line canon.
A: Again destroy the empire. durring the great war the thalmor killed all of the dark brotherhood, except cicero, in cyrodiil. the thalmor again would kill all of the dark brotherhood if the dragonborn already hasn't and they would kill the emperor if the dragonborn already hasn't.
Why the empire will fall: the empire will fall because no one nation can defeat the thalmor. the only reason hammerfell got out alive is because the thalmor just got out of a war with the empire. The only reason the empire got out alive is because imperials+nords> Aldmeri dominion. This time around skyrim and cyrodiil will both be to weak to defeat the thalmor. the chances of them forming an alliance is very slim to none considering the imperials see the nords as, falsely fighting for talos by destroying talos' greatest lasting effect on nirn... the empire. While the nords see the empire as the ultimate betrayers of talos by renouncing the the person who created the empire.
hammerfell sees the empire as betraying them and skyrim won't even let redguards into whiterun to search for a thalmor sympathizer let alone let armys into skyrim to fight the thalmor.
ysolda said it best "one bad apple spoils the bunch." and if the thalmor just being elves makes all elves bad in the eyes of the stormcloaks then the forsworn being brentons would make all brentons bad in their eyes. and when ever hammerfell and highrock where not in an alliance they fighting over control on the illiac bay(look at the game daggerfall).
Although the threat the thalmor pose supersedes past differences, the human nations are not fully aware of the threat the thalmor pose.
Predictions:
I predict that the thalmor will be in control of cyrodiil and skyrim by the next game and we will probably have to defeat the thalmor from inside the dominion
