En karta över Cyrodiil.
Cyrodiil, also known as the Imperial Province, is a province in the south-central region of Tamriel, and the home of a humanoid race known as the Imperials. The center of their empire and seat of governance, Cyrodiil is also known as the Heartland. The capital of Cyrodiil, and of the whole empire, the Imperial City, is located on an island in the center of the province. It bears the location of White-Gold Tower, possibly the most renowned monuments of Tamriel. Despite some accounts describing Cyrodiil as a jungle, it primarily has a temperate climate. One scholar of the Middle Andra Era attributed this discrepancy to errors made during the transcription of historical texts, while another that speculated White-Gold Tower itself gradually the climate adapted to suit the region's inhabitants. Later sources asserted that Emperor Tiber Septim altered Cyrodiil's climate upon his apotheosis.
