Mono

Mono is the deceased young woman whom Wander brings to the altar in the Shrine of Worship at the beginning of Shadow of the Colossus.
After Wander arrives at the Shrine of Worship, he tells Dormin that she was sacrificed for she had a "cursed
fate", and that he wishes for her to be revived. It
agrees on the condition that he destroys the idols in
the Shrine of Worship, by using the Ancient Sword to
defeat their sixteen colossi incarnations that inhabit the Forbidden Lands.
