Mother Carmel was a child trafficker who operated in the Underworld decades ago under the alias "Mountain Witch." She ran an orphanage called the Sheep's House, where she cultivated a reputation as a benevolent caretaker—earning her the nickname "Holy Mother"—while secretly selling her orphan charges to the World Government every two years to be trained as Marines or Cipher Pol agents. She died 63 years ago.
Her most notable ward was a young Charlotte Linlin, who would eventually rise to become one of the Four Emperors, Big Mom. Carmel's fate remains tied to Linlin's early history, though the exact circumstances of her death have long been shrouded in mystery within the broader One Piece narrative.
