Stormcloaks have a role to be the opposition of the Imperials. This faction featured in The Elder Scrolls V: Skyrim is led by Ulfric Stormcloak. They are in conflict with Imperials since they oppose the Imperial Legion's attempt to create alliance with Cyrodilic and Thalmor Empire in Skyrim. The Dragonborn may choose to support either Stormcloaks or Imperial Legion.
