I've found, despite my searching through The Imperial Library site as well as UESP, I've found very few details on two subjects: The Thalmor and the Great War. I've read Rising Threat, and I've read the admittedly brief report on the War itself. However UESP is dry of any details regarding the Thalmor, and searching for anything on The Great War inevitably leads back to the report or leads to the Fourth Era timeline.
The Thalmor are frustratingly mysterious in motive, numbers, and leadership. And the question I also have to beg is whether or not the Thalmor are an entirely Altmer organization, or whether or not there are Bosmer in its ranks. There was some talk within the game and within some sources in the Library that there had been a "Great Purge" of sorts, clearing out those not of pure blood. It's therefore not out of the question that the Thalmor is entirely Altmer. Probably on purpose, this mirrors the purges in Germany in the 1930s; it's no coincidence that the Thalmor wizard robes have the appearance and function of the uniforms of Nazi Germany's Schutzstaffel (SS). However, in the real-life Nazi expansion, the Nazis relied on an extensive number of collaborators, particularly in the Balkans and in Austria. A number of these even made their way into Himmler's SS corps, and some presided over the extermination camps. Given the similarity of the Thalmor to Nazi Germany, is it out of the question then, that there might be Bosmer or even Khajiit in their ranks?
And exactly what is it that they're after? It's been said that they are after the complete unmaking of the world, but even the Thalmor have to know that it's an unrealistic ambition. The best they can hope for is a world without Men, and that seems to me like an ambition that's out of their reach for the forseeable future. So precisealy what is it they are after?
And the Great War. There is almost nothing known about any of the commanders outside of Titus Mede II. What exactly were the tactics used in the various skirmishes and battles? All the tactical coverage goes to the Battle of Red Ring, but almost nothing on early battles of the war. What kind of commander was General Naarifin? What was Lady Arranelya's fate? What about the battles in Hammerfell?
Details seem scant.
