In Morrowind you had both the Nine Divines and the Tribunal, so do you think the Eight Divines will be in Skyrim along with the Nordic pantheon? And should other pantheons be present?

Also, should there be a religious faction? And if it is, how do you want them to be handeled(they won't be major factions like the Companions, Thieves Guild etc. after all)?

There should be joinable daedric cults, or other joinable religious cults viewd as deviant by the major religious factions. For instance. There should be a joinable outlawed church of Talos.

I've always wondered, Is there an Aetheist group in Tamriel? People who don't believe in Gods and such?

It's harder not to believe in them when they exist. Elsa god-hater comes to mind.

As a non believer I don't see why we atheists or other non believers should have groups. The reason for having a church is for the believers to have their religious views confirmed when reality mocks them.

In Tamriel, the gods are visibly present, sometimes even corporeally so. There's really no niche for atheism in a universe like that.

But it could be a niche for people opposing the Gods. Believing that man should make his own luck and say screw the Gods.

But she doesn't believe in the Nine Divines, she believes in the Daedra, no doubt they exist.
