How to fix Oblivion:
(Most of this is based on the Cyrodiil described in The Pocket Guide to the Empire, First Edition.)
1. Instead of being the diverse landscape with temperate forests, snowy mountains, and rolling hills, the Imperial Province would consist of mostly tropical jungle and rain forest, except for the Nibenay Bay. The Nibenay Bay would be a fertile grassland that surrounds the Imperial Isle (which I will discuss later), and be chopped up by rivers that flow from Lake Rumare to the rest of Cyrodiil. These rivers are the foundation Cyrodiil; most cities and settlements are built on the riverbanks. The jungle grows even more alien to the southeast, near Black Marsh, and fades towards the western ocean.
2. The Nibenese-Colovian split would be visible. The Nibenese are the mystic, flamboyant, ceremonial people of Eastern Cyrodiil, who decorate themselves with garish clothing, face paint and tattoos, and other ceremonial garb; they have a hierarchy of workers, merchant-lords, priests, and finally the battlemages, who would serve as the Counts of Nibenay. The Colovians are the rugged, simple, hearty people of Western Cyrodiil, who dress simply and comfortably with little regard to style; many of their children go on to join the Imperial Legion, and the Counts of Colovia would all be Legionnaires, preferring their Legion battle armor over regal clothing.
3. The Imperial City would be actually astounding. It would be built on multiple islands within Lake Rumare, connected by ships that travel around the city, gondolas, and enormous bridges that host entire neighborhoods. The Palace, instead of being the White-Gold Tower, would be an actual palace that resembles the "crown of sunrays" it was described as. Green Emperor Way would feature the magical talking heads of previous emperors. The City would be enormous, and would take a lot of Akaviri influence.
4. Akavir would have a very real effect on Cyrodiil. The Nibenese Counts would have Akaviri features, and possibly decorate themselves in clothes of snakeskin and masks. Nibenese cities would feature a great deal of Akaviri influence. Wealthy homes in Cyrodiil would be guarded Post too long. Click here to view the full text.
