>>11088158Ulfric wasn't a Thalmor pawn, he was called an 'uncooperative asset' because the civil war benefits the Dominion by undermining the Empire's hold on Skyrim. That same dossier goes onto explain that a Stormcloak victory should be avoided at all costs. Also, the Empire isn't a puppet regime of the Thalmor because they weren't conquered completely.
Not that I care because High Elves are my favorite race anyway.
