In Hyrule Warriors, a fragment of Ganondorf's soul uses his power to remove the light (which became the White Sorceress, Lana) from the soul of the Guardian of Time transforming her into the Dark Sorceress, Cia.
Though Zelda is known to possess innate mystical powers, the essence of Nayru, wielded by Zelda using the Triforce of Wisdom, enhances these abilities.
