Merida found the Will o' the Wisps after she had a fight with her mother, Queen Elinor. From the Ancient Circle of Stone, she followed the wisps to the Witch's Cottage, where she was given a potion that could change her mother's mind about Merida's marriage. After drinking the potion, her mother changed into a bear, and at the sunrise of the third day, Elinor would be a bear forever: unless Merida mended their broken family bond. Merida encountered Mor'du, the ancient bear that had similar past as her own. Through Mor'du's story, she saved her mother from the curse.
