Achim is 11 years old when he moves from the orphanage to the house by the sea. Here everything is strange and new. But one day he discovers an unusual door that leads to a circular room with walls made of rough stone. The light coming through the window is hazy, as if the room is under water. It is a magic room - which he calls “The Adopted Room” - belonging to another world. And on a bed in the room sits a boy who is waiting to take Achim with him into the realm of the powerful Nameless One.
