The term Sayyadina (meaning "friend of God" in Chakobsa) was used by the Fremen to describe their lower-ranking priestesses who had not yet changed the Water of Life and become Reverend Mothers. Often, a woman would be consecrated as Sayyadina at the same time that the previous Sayyadina attempted the spice agony, so that all would not be lost if the potential Reverend Mother failed and died. This occurred when Ramallo, at the end of her life, supervised Lady Jessica's spice agony; since Ramallo was moments from death, Chani, daughter of Liet, was consecrated as Sayyadina in the event that Jessica did not survive.
