Fenrir has been known to be the reason armageddon occurs and he is encrusted on this rotating pendant encircled by the wayward symbol.
He is also known as the Fenris Wolf (also given as Fenris-wolf) and Vanargand (“monster of van”) usually understood to mean “creature of expectation” because he was prophesied to participate in the destruction of the gods. His name is pronounced Fen-rear, and he was born of the union of Loki and the giantess Angrboda. A prophecy foretold that the children of Loki would cause the gods of Asgard trouble and so they were taken from Jotunheim, land of the giants where they lived with their mother, and brought to Asgard. Odin then hurled Jormungandr into the sea, dropped Hel into the depths of the realm of Niflheim, and, eventually, had Fenrir chained to a rock. All three children would avenge themselves at Ragnarök.
