Tullius is an Imperial originally from Cyrodiil, who has been sent to Skyrim by Emperor Titus Mede II to quell the uprising of the Stormcloaks. Tullius is first seen at Helgen, presiding over the attempted execution of Ulfric Stormcloak for his rebellion against Imperial authority and the murder of Torygg, Skyrim's High King. However, Alduin's attack on the garrison of Helgen allowed Ulfric and the other captured rebels to escape back to Windhelm to reorganize.
