Become an Anima.
Break the Doubt and cast off its oppressive influence. Unlock the power of your dreams and make magic real. See the Waking World with a dreamer's eyes and uncover the mystic denizens that live shoulder to shoulder with the rest of humanity. Places of myth, artifacts of power - learn all you can and be ready to face your own nightmares. Reavers will hunt you, the Doubt will pressure you, and groups like M.O.X. will seek to put you down, but stand tall and fight for your dreams, however strange or wonderful they may be.
Come learn about a society of dreamers who wield magic, standing divided on what it all means and how to deal with it. Dreams are their battlefields, so come wage war against the Doubt and learn the truth all Anima cling to.
Magic is Real, and Dreams Matter.
