First of all, The Nords use to endorse the medes, The Ulfric turned there Disain into Hatred, Second, THE Bloody NORDS STarted the Empire!, Third Ulfric is POWER hungry, Everyone except his followers think so, He wants to OWN skyrim, Not unify it.
Who started the Empire?
The answer is Cuhlecain. A Colovian. Tiber Septim had him murdered to become the Emperor. During Tiber Septim's time, the majority of the Nords didn't care about the Empire. Their plan was to merely
outlast it. The vast, vast, vast majoriy of Imperial troops came from Colovia. Skyrim did
nothing. They fought Tiber, were traumatized into betraying their Breton allies, and meekly offered their support to Tiber. They did not start the Empire. The Nords are not one person.
Oh, and Tiber was from High Rock. Not Skyrim. His entire history is built on lies.
Even some Stormcloaks hate Ulfric. But Ulfric being scum should not stop the idea of a free Skyrim.
