Vana'diel is about to witness the realization of an ancient legend. Uncharted territories have been discovered on its fringes, and adventurers speak in hushed tones of settlements long forgotten. It is said that those who dwell in Vana'diel were born of the tears shed by Altana, Goddess of the Dawn. But tales tell of an opposite to the loving deity--a divinity know as Promathia, God of Twilight. While Altana soars on wings of freedom, Promathia is bound in chains: his confinement is said to be self-imposed. Can this legend be true? And do rumors of the frightening phenomenon occurring in faraway lands have any relation to Promathia? The unfolding mystery of Chains of Promathia will bring adventurers ever closer to the astonishing truth behind Vana'diel's origin.
