Just want to point this out to all supporters of the Empire and Stormcloaks. This is the Thalmor at hand, they are trying to take all of the land by dividing and conquering all the provinces. After the Oblivion Crisis they get power and take over the Summerset Isle. Next made Valenwood go with the A.D., but after an attack. They see the Empire and see a golden opportunity, divide the 3 parts and conquer all. Divide Hammerfell with loss of land, divide Skyrim will Talos ban, then kill of the Empire.
Its just the Thalmor using tactics to destroy the Empire one province at a time.
And the Ultimatum that was given at first is the same to the WGC at the end.
Forgot Elsywer, they said to use magic to bring back the moons to gain favor of the ruling body.
