'On Shadows'; a citation from the Book of Father Volume IV:

"A mark at your feet that'll chase when you run, It hides in the night, and thrives in the sun, Even in death, it's presence is plain, Doing no harm and feeling no pain. The Twilight fell first, sombre and screaming, The Dusk soon followed, golden and gleaming, The Midnight came last, with fire in their eyes, The Shadows have fallen: and fallen, they rise."
