Trivia

 * Urd, Verandi, and Skuld are Old Norse for "fate", "present" and "future". They are three figures roughly analogous to the Greek Fates from a poem in the Poetic Edda, which is possibly the religious text in question.
 * "A Wind Age, a Wolf Age" is also a possible reference to the Poetic Edda, specifically in a poem about Ragnorak's aftermath. The terms were also used in Bungie's Myth series.
 * The Hesperides were nymphs who tended to a blissful garden. They were daughters of Hesperus the Evening Star, also known as the planet Venus.
