Macha (/ˈmaxə/) is the Third Star of the Six Stars. She has green hair, light skin, and a childlike face. She has loved Shura before she was even born, and for that reason had been chained down in the center of the stone circles of the Underworld, used as a trap against Shura.
Unable to move about, Macha had created a child Duendy of her own, Cerberus, in the same fashion that her mother Deirdre had created her. Through Cerberus and her own telepathic ability, Macha was able to guide Shura through the underworld and assist him against other powerful Duendies.
As she convinced Shura to H her in order to kill her and obtain the key out of the Underworld, she fulfilled her own purpose of being -- to be H-ed by the person she loved.
Macha has a twin sister, Badb.
