Holda

Holda (Frau Hold, Holde, Holle, Hulda, or Huldra) is the supernatural being of spinning, childbirth, domestic animals, and is associated with winter and witches.

She had no children but was seen as the protector of children and had a sacred pool from which the souls of newborn children could enter the world in by. She is also associated with the Mistress of "The Wild Hunt", which is a phantom group of huntsmen. She also leads female night-spirits to join "The Wild Hunt".

Tales of Evermagic
Holda has an ambiguous place in the Tales of Evermagic. She is only mentioned in A Witch's Song by Evermagic.

Reliving
Nim of A Witch's Song is originally reliving the evil witch from Hansel and Gretel but her kind and gentle nature clashes with the magic so that it dissolves into chaos. To fix this, Evermagic changes the magic surrounding Nim so that the story is no longer trying to make her act an evil part, but alters it so that she is now a reliving of Frau Holda.
