The Imperial City is the capital city of Cyrodiil and the Septim Empire during The Elder Scrolls IV: Oblivion. Located on the City Isle in the midst of Lake Rumare in the Heartlands it is visible from many miles mainly due to White-Gold Tower which is looming over the city. The Ayleid-built city consists of a total of ten districts. Six of them are arranged in a circle around the central Palace District. The remaining three are located outside the main city walls. A vast sewer system interconnected with ruined Ayleid structures run under the city.
