The idea is that there should be Temples in different zones that players can join that correspond to the specific Aedra/Daedra they worship. It would be only on temple/faction that you can join per character and would give you certain bonuses as you rank up.
For Example: As you you level up in the temple/faction you gain certain household items like statues and banners, costumes, mounts, and eventually a themed house.
Skill Styles: each temple/faction would offer different skill styles depending on the class. Azura's temple could offer different skill styles for your winged twilight. Hircine's temple can offer a skill morph for the werewolf to make it a werebear or wereboar. Arkay can offer different templar spears. Ect, ect.
There would also have to be limitations. For example: you can only belong to one Temple. Certain classes and world skills can't join a specific temple (Necromancers and Vampires wouldn't join Meridia's temple). So on and so fourth.
Just an idea I had to improve the lives of player and RPers. Let me know what you think and please comment down below with any criticism or suggestions.
