In the Witcher universe, the Crones of Crookback Bog are three ancient and powerful entities living in Velen. Known for their cruelty, they rule Crookback Bog and play a key role in The Witcher 3: Wild Hunt. Their conflict with a mysterious spirit affects many lives, including Geralt's search for Ciri.

In The Witcher series, witches are typically wise-women or healers, often older women, and differ from sorceresses who are more numerous and skilled in magic. Witches, such as the Crones of Crookback Bog, may take on various forms and are rooted in folklore, while sorceresses belong to a structured magical community.

In The Witcher series, witches are wise-women or healers, often older and sometimes called hags. Examples include Abigail and the healer in Murky Waters. Witchers, on the other hand, are mutated monster hunters using simple spells known as Signs. They are distinct from mages and are skeptical of complex magic.

Abigail, a witch in The Witcher game, lives near Vizima and is skilled in alchemy. Villagers blame her for misfortunes, leading to a mob threatening her. Geralt can choose to save her from lynching, resulting in her leaving the Outskirts and later appearing in Murky Waters, trading in herbs and potions.

The Witch of Lynx Crag is a key figure in The Witcher lore, featured in the Blood and Wine expansion. Living in a hut on Lynx Crag in Toussaint, she is feared for her magic and tendency to twist her aid, often causing harm. In 'A Knight's Tales,' Geralt confronts her to lift a drought curse. Despite her promises, she deceives him, resulting in tragic events. Her actions underscore themes of deception and the perilous nature of magic in the Witcher universe.
