In turn, the Empire works closely with Jarl Elisif in its attempts to squash the Stormcloak Rebellion.
The true reasons for Elisif's support of the Empire are debatable, but factors involved included the fact that her husband Torygg served under the Emperor (though Torygg's own loyalty is debatable), and the fact that Solitude serves as the base of Imperial military power in Skyrim at the time of the Stormcloak Rebellion. It was after Torygg's death, at the hand of Ulfric Stormcloak, that Elisif became the Jarl of Solitude, and following her assumption to power in Solitude, Elisif would work in close cooperation with the Third Empire against Ulfric Stormcloak and the Stormcloak Rebellion. The palace stands directly across from Castle Dour, the headquarters of the Imperial military forces in Skyrim. Elisif can be found in the Blue Palace located in the southeast of Solitude.
