Calon Arang

Calon Arang is a character in Balinese folklore from the 12th century. It is still unknown who composed this story.
It is said that Calon Arang was a widow, powerful in black magic, who often damaged farmer's crops and caused disease to come. She had a girl, named Ratna Manggali, who, though beautiful, could not get a husband because people were afraid of her mother. Because of the difficulties faced by her daughter, Calon Arang was angry and she intended to take revenge by kidnapping a young girl. She brought the girl to a temple to be sacrificed to the goddess Durga. The next day, a great flood engulfed the village and many people died. Disease also appeared.
King Airlangga, who had heard of this matter,
then asked for his advisor, Empu Baradah, to deal with this problem. Empu Baradah then sent his disciple, Empu Bahula, to be married to Ratna. Both were married with a huge feast that lasted seven days and seven nights, and the situation returned to normal.
Calon Arang had a book that contained magic incantations. One day, this book was found by Empu Bahula, who turned it over to Empu Baradah. As soon as Calon Arang knew that the book had been stolen, she became angry and decided to fight Empu Baradah. Without the help of Durga, Calon Arang was defeated. Since she was defeated, the village was safe from the threat of Calon Arang's black magic.
