One.

Long ago, the Goddess Fortune created 22 souls; each one a crafted special by her hands, guardians to the world she had so lovingly watched over. Each soul became a new card in her deck, the pick-and-pull of fate's whispery choosing. These souls became known as the Arcana, from which fabled existence fortune tellers base their all-knowing cards on.
When the world is threatened by a powerful foe, it is up to these Arcana to come into their destiny and bequest their Godess Fortune.
