The Moonlight Stone is an object which was made by the evil mamodo, Zofis. It was used to manipulate the hearts of the many humans and Ancient Mamodo who fought in his "army". That object produces a light which can replicate that of the moon, and initially was used to free all the ancient mamodo from their Stone Tablets. The Moonlight stone also has the ability to heal wounds and restore the heart energy of humans, who have their minds and heart controlled so that they do anything that their mamodo partner wants, like cast a spell, without the mamodo saying anything. However, not all the humans who fought with the ancient mamodo had their minds controlled, like Gensou, Dalia Anjé and Robert Vile.
