What does your "Mighty Empire" have left? Cyrodill, Highrock. That is it.
The Mighty Empire has had less. It also has half of Skyrim.
Though I wouldn't be boasting about that, since a greatly weakened Empire is still larger than the strongest the Aldmeri Dominion has been in all three times there has been one.
The Fourth Legion is occupied in Skyrim.
The Legions in Skryim are not the Fourth Legion, they are Auxiliary Legions made up of locally trained militia. The mention of the Fourth Legion was actually a mistake on a website, there is no actual mention to any of the Legions in Skyrim having a number.
3 were completely annihilated during the great war. The other 5 that fought in the battle of the red ring lost half their men. In the 3rd Era the Legion were strong a there were 18 of them.
There were 18 Legions under Titus Mede. As mentioned in the novels, Attrebus came across ex Legionnaires from the Eighteenth Legion who served with and loved his father, Titus Mede.
2 were decommissioned, when Argonia left the Empire. Another when the Red Mountain erupted.
Source? There has never been a mention of an Imperial Legion being decommissioned throughout TES history. The only example of a Legion being changed is when the Third Legion was absorbed by the newly formed Ruby Legions during the reign of Tiber Septim.
Another 2 that are now "Stormcloaks".
No.
Surely another one since you turned your back on Hammerfell, and Orsinium.
Hammerfell was removed from the Empire. Though it is interesting that when the Empire denounces Hammerfell, the Empire betrayed and turned their back. But when General Aakar of Hammerfell fought against the Empire during the Stormcrown Interregnum, the Redguards didn't feel betrayed...
As for Orsinium. The Legions actually helped them. The 7th and 15th Legions stepped in when they were attacked, putting themselves into harms way. They saved many Orcs, and escorted a lot of Orc refugees into Skyrim.
So out of 18 Legions at the start of the 4th era, only 7 and a half remain. If it took 18 to fight us to a stand still imagine the horror you dogs will come to find with less than half that.
You have no idea the current strength of the Empire. Except that the Empire had a five year head start in preparing for the Second Great War, while you're playing catch up. When I said 7.5 full Legions possibly remain after the Great War, twenty six years ago. I was guessing.
As far as the terms of the Concordat they are exactly what we demanded, before the war. And that is what we got. Be humbled.
Nearly. Only three terms were the same, Southern Hammerfell was already occupied, the Blades were all but destroyed during the Great War and the banning on Talos was always going to happen. Of course the Concordat would have the terms the Aldmeri wanted, the Empire went to them for temporary peace. Still doesn't protect you from nearly the entire Imperial army on the Dominion's border.
