Depending on your chosen character, you will live in a house as them. The “Anonymous god” will give you options to be someone else. Either fictional, historic, an animal, or currently living person. Once you choose your character, you will start to change. The “Narrator” is a God technically, but not a religious one. The “Narrator” doesn’t care about your decision. If you choose your character and change your mind, he can give you options again so you can be someone else.
