This chapter's epigraph comes from the opening lines of the novel, "The Four Realms" . It's a quote from the novel's opening lines, which states that "the four realms" are the four levels of the human body. The four levels are the highest levels of a person's body, and they're the ones that determine whether or not a person is immortal or not. In other words, the four realms determine whether a person can live or die. In this case, the "four realms" is the realm of the undead. The undead are the undead of the underworld, and the four tigers are the ones who have the power to kill them. This is why the undead are called "the undead" in the first place. They're also called the undead because they can't be killed by the undead, because they are immortal. So the undead aren't the only undead on the face of the earth. There are also other undead out there, including the ghosts of the gods, who are also called "goddess" because they have the ability to speak. So, the undead have a lot more power than the undead do. So they can kill a lot of people, but they can also kill the gods themselves. So there's no way the undead can be defeated by the tigers, because the tigers have killed the gods. So now the tigers need to figure out how to destroy the ghosts.
