Hel, Norse Mythology. Trickster’s Daughter, Proud Goddess of the Dead: Hel was one of Loki’s most problematic children (her brothers are Fafnir and Jormungandr). Sensing her power, Odin allowed her a portion of the dead and her own kingdom to rule. She is described as half human and half icy-blue, like an ice giant. Hel’s army of the dead will return to fight for Loki and his other children during Ragnarok. Art by Luis Royo.
