Everyone starts off together, pretty much all on the same hill when they wake up. What they believe in doesn't have to be a new religion or faith, many people are using what we have now, since it is a modern story meant to be real, or as real as possible in the fantastical sense. The roles are mulling around, shaking of the sleep they have just come out of, the IC (when you get a chance to look it) may help clear anything up as well. ^^
