Thokk
The Hag

Upon Baldur’s death, emissaries were sent to Hella begging for his release from her realm. She finally agreed, provided that every single living being in the universe mourned for Baldur. Frigga, Baldur’s mother, journeyed through the various realms begging everyone to weep for her beloved son.

Everyone did until finally she reached the cave of the troll-hag Thokk (“Coal”). Thokk, a bitter, gloomy hag sat in the darkness of her cave and point blank refused to weep for Baldur, saying Hella could keep him, thus dooming all efforts at resurrection.

Thokk is generally believed to have been Loki in disguise. (Loki was responsible for Baldur’s death.) Alternatively, some perceive Thokk as among Angerboda’s seemingly endless manifestations. Angerboda was Loki’s first wife and possibly his sister; Hella, Queen of the Dead, is their daughter.
