Fenrir (pronounced “FEN-rir;” Old Norse Fenrir, “He Who Dwells in the Marshes”
is the most infamous of the many wolves in Norse mythology. His importance for the
pre-Christian Scandinavians is demonstrated by his being depicted on numerous surviving runestones,
not to mention his ubiquity in Old Norse literary sources.
He’s the son of the god Loki and the giantess Angrboda, which makes him the
brother of the serpent Jormungand and the underworld goddess Hel.
