Behind the scenes

 * The name Fenric is derived from the name of the wolf.
 * The Gods of Ragnarok's name is from the Nordic, which is often misunderstood as the "End of the World" or Armageddon. While an important part of Ragnarök is a climactic and cataclysmic battle, it ultimately ends with the renewal of the world as new and fertile.
 * One translation of Ragnarök is "the End of the Gods"; thus; the Gods of Ragnarok are "the Gods of the End of the Gods". This could be interpreted either as an added layer of meaning, or as nonsense.
