Thokk

In Norse mythology, Thokk (possibly Loki in disguise) was the frost giantess who refused to weep for the slain Baldur. Hel, the queen of the dead, said that, if all inhabitants of the nine worlds wept for him, she would allow him to rise. Thokk was the only one who refused to shed a tear, thus forcing him to stay dead until Ragnarok.
