Detail: From the Old Norse name Sigurðr, which was derived from the elements sigr “victory” and varðr “guardian”.
Sigurd is a hero in Norse legend, which tells how his foster-father Regin sent him to recover a hoard of gold guarded by the dragon Fafnir. After slaying the dragon, Sigurd tasted some of its blood, enabling him to understand the language of birds. By listening to the birds Sigurd learned that Regin was planning to betray him.
4 Calling Birds refers to the Four Gospels and/or the Four Evangelists
Detail: The meaning Fenrir is disputed on is thought to be the Old Norse “fen-dweller”. Another idea is the short form of Fenrisúlfr. Which means “Fenris-wolf”, derived from the name Fenris combined with Old Norse úlfr “wolf.” The etymology of the name Fenris is uncertain; it is thought that it is derived from Old Norse fen “moor, marsh, swamp” and Old Norse hris “brushwood, shrub.”
In Norse mythology, Fenrir is a monstrous wolf and is foretold to kill the god Odin during the events of Ragnarök (the end of the world).
J. K. Rowling also uses the name for one of her werewolf characters, Fenrir Greyback, in the popular Harry Potter series.
Detail: According to Norse mythology, the first humans were carved from trees by Odin and his brothers Vili and Ve. They cut down an Ash tree and from it made the first man, Ask. From an elm tree they carved the first woman, Embla.
