" I figure the universe is basically like a machine. I don't know who made it, if it was the Fates, or the gods, or capital-G God, or whatever. But it chugs along the way it's supposed to most of the time. Sure, little pieces break and stuff goes haywire once in a while, but mostly...things happen for a reason. "

― Rick Riordan , The House of Hades (The Heroes of Olympus, #4)
