A good example would be the Horus Heresy series of the Warhammer 40.000 universe. It currently has 11 books out, and with 4 still underway (and that's probably not even the end of it). So far, 8 different authors have penned the different books. The series is internally consistent, contains gods and daemons, even a saint, and some view the Emperor of Mankind as a living god.
See here
I hunt for the truth
I am the one Orgasmatron, the outstretched grasping hand
My image is of agony, my servants rape the land
Obsequious and arrogant, clandestine and vain
Two thousand years of misery, of torture in my name
Hypocrisy made paramount, paranoia the law
My name is called religion, sadistic, sacred whore.
