A winter's promise

Long ago, following a cataclysm called 'The Tear,' the world was shattered into many floating celestial islands.

Known now as Arks, each has developed in distinct ways and at a different pace; each seems to possess its own unique relationship to time.

Ophelia lives on Anima, an ark where objects have souls, with which Ophelia can communicate.

When she is promised in marriage to Thorn, from the powerful Dragon clan, Ophelia must leave her family and follow her fiancee to the floating capital on the distant Ark of the Pole.

Though she doesn't know it yet, she has become a pawn in a deadly plot.
