Margaret Driscoll Ley is Nathaniel's younger sister.

Although not appearing directly, Margaret is well known to readers through narrative in Book One, "Serch Bythol". She becomes an active voice in Book Two, "Inner Magnets", and her the significance of her role is slowly divulged.

On the surface, Margaret is a product of the material world. She loves fashion and cosmetics, and is smitten with the idea of romantic love. To the people who know Margaret well, she is acutely sensitive, intuitive and mediumistic. She is often underrated and while it hurts her, it ultimately serves her destiny.

Margaret's role in the story increases with each volume of the quartet.

She plays an integral role in the conclusion of Book Four, "Tammabukku".
