Wikipedia
The crone is a stock character in folklore and fairy tale, an old woman who is usually disagreeable, malicious, or sinister in manner, often with magical or supernatural associations that can make her either helpful or obstructing. She is marginalized by her exclusion from the reproductive cycle, and her proximity to death places her in contact with occult wisdom. As a character type, the crone shares characteristics with the hag.
