Cyrodiil/Religion

Nine Divines
The Nine Divines are the most important religious order in Tamriel. The religion combines the eight Aedra with the founder of the Third Empire, Tiber Septim (Talos). There are six gods and three goddesses. In Cyrodiil, there is a chapel in each major city, venerating the divines. There are also wayshrines along the roads that are devoted to the Nine Divines. These Aedra also appear in various combinations in the pantheons of other cultures.

Because Talos was not originally one of the Divines, in some religious sects they are referred to as "The Eight And One". As of 4E 200, Talos was effectively removed from the pantheon of the Gods and The Eight Divines worship resumed. Thalmor agents from the Aldmeri Dominion, per the White-Gold Concordat, ensure that the worship of Talos remains an illegal activity.

Alessian Order
This monotheistic religion was once very popular, but today only remnants of its faith remain. It started in the coastal jungle of what is now the Colovian west, where a prophet named Marukh, who had spoken to the "Enlightened One," Saint Alessia, began to question the validity of Elven rule. These sentiments led to an increasingly abstract and unknowable depiction of a Single God. The Alessians were wise enough to realize that they had to incorporate the ancient polytheistic elements into their new religion for it to find a wide acceptance. The divine aspects worshipped by the various humans and Aldmeri were recognizable in the guise of the myriad saints and spirits of the evolving Alessian canon. It wasn't long before the Order was the authority on every religion in Tamriel, and their power grew to earthshaking proportions. Nearly a third of the First Era passed under their theocratic rule. When its priesthood had become too widespread to support itself, the Order began to fight among itself. With the severance of the territories of West Cyrodiilfrom the Empire, too much money and land had been lost. The War of Righteousness broke out, and the Order which had almost ruled the world undid itself in a ten year span.
