This chapter's epigraph comes from the opening lines of Chapter 427, "Letter by letter" . It's a quote from a famous poem by the English poet William Butler Yeats. It says, "I am a poet, but I am not a poet; I am neither a poet nor a novelist. I am a writer, but not a novelist." In other words, it's not a poem, but rather a poem that's been written by someone else. The poem is entitled "Symbolism," which means, "Symbol of something." In this case, it means "Symbol" or "Symbol." The poem's title is a reference to the symbol of the afterlife, which is symbolized by the soul core. The soul core is the key to the afterlife because it holds the soul of the dead. If someone dies, the soul will test the soul's mind and determine whether or not the soul belongs to them. If the soul dies, it will be a zombie. So, if someone dies as a zombie, that person will be tested by the spirit of the soul and will be ejected from the afterlife if they don't live. This is why the soul cores were left in the first place
