[Triton]

I'm totally confused about the Empty Man, so forgive the silly questions...

1. So, the Empty Man is basically a demon that the Pontifix cult worships who can be summoned when blowing into something while standing on a bridge?

2. I understand that Paul was the first "tulpa" used to channel the Empty Man into the real world, but what did he do while they were hiking to be chosen? That just seems kind of random

3. Amanda says that the Pontifix cult "created" James to be the next tulpa after Paul and all of his memories were fake; What does she mean they "created" him......was he just some random guy the Pontifix cult took off the street and brainwashed him?

4. Explain the whispering; What was the significance of it each time it would happen?
