Wyllow took care of the forest of Wyllowwood.
Wyllow met and fell in love with Launsar Hendrake, an apprentice of Halaster Blackcloak, during one of his missions outside Waterdeep. Hendrake wed her and took his wife to Undermountain. There, with Halaster's permission and help, they created the garden of Wyllowwood.
However, Wyllow discovered the evil nature of Hendrake and at last she killed him. Afterward, she became totally crazy but in time regained a little of her sanity.
