Lilia is a young woman that is thrown out of her tribe to exile in the wilderness, but she sees Memnoch in his human form and offers herself to him. When Memnoch is taken by God's light, she does not run away but stays and watches. When Memnoch is cast down from the heavens, she takes him to the tribe and is readmitted within them. She becomes Memnoch's mate, though she steps aside so that he may lay with others and spread the seed of the angels.
