This chapter's epigraph comes from a famous poem by the English poet William Butler Yeats. In this poem, he says that the "armillary sphere" is the "true power" of the universe, and that it is one of seven treasures on the earth. He says that if he did not get out of the sphere in time, he would not be able to use its power. He then goes on to say that the sphere can become "a devastating weapon" at the right time, when it is used to gather the signal of righteous people. He tells the evil witch that if she still wants to live, she should grab the "chaos magic" and get lost. The evil witch says that once they have surrounded all of the disciples of the righteous, she can summon them all and kill them all. Then she says that she can use the sphere to encircle the city.
