Play as Therese, who's somehow found herself unable to leave a cathedral that she doesn't remember entering. Things only get stranger when a young boy, Eldin, who Therese has never met claims to know her. Eldin claims that the two of you are sharing a dream-- a dream that neither of you can wake up from. What can you believe? Who can you trust? Dive in and try to uncover the secrets hidden within, and outside, of your dreams...
