The Elder Scrolls: Fate of Tamriel
Cyrodiil is mostly an expanse of forest and mountains. Its heart, the Nibenay Valley, is a vast plain, enclosed by equatorial rain forests. Many rivers flow through this area, and as one ventures further down the rivers, the land slowly becomes more sub-tropical, eventually giving way to the swamps of the Black Marsh. The elevation rises gradually to the west and sharply to the north. The western part of the region is relatively dry. The Velothi Mountains (Valus Mountains, as the Imperials call them) to the east have some roads, but most travel in Cyrodiil is dominated by rivers. Cyrodiil is the most diverse province in terms of geography and climate.
Imperial culture is a pragmatic melting pot of the various contrasting cultures of the provinces, unified by the strong hereditary Emperor and bureaucracy, the rule of law, a professional army, and tolerance of disparate polytheistic cult worships. Education and wealth is broadly distributed through all social classes where Imperial culture has flourished. Many citizens are literate and protected under Imperial Law.
