I'm just going to jump passed the Skyrim main story and right into the rest of this. Alduin is vanquished, the Civil War is won by the Empire and a new threat looms over the horizon. The Thalmor know of the steadily regrowing Blades. They also know that Legate Saya is a threat to their operations, especially after she threw in with Madanach and the Forsworn. Madanach has promised the conquest of the Reach to Saya, Elenwen and General Tullius. War again looms on the horizon and the war for Skyrim has only just begun.
