This chapter's epigraph is from a famous poem by the English poet William Butler Yeats. It's a poem about a young man who's about to be killed by his father's enemy. The young man is about to kill his father when he hears the voice of a demon. The demon's name is Duanjian, and he's the son of Duan jian, the father of the young woman in the poem. Duan-jian's mother is also a demon, and she's also the one who seduced the young man in the first place.
