Rumors swirl of a cursed apartment in the house where children vanish, never to be seen again. Plagued by strange visions, and fearing that she is losing her mind, Sara soon finds herself drawn to the apartment in search of answers. Instead, she is confronted by Lamia, a beautiful woman from a strange world called Cellestria. Trapped in a mosaic on the wall of the apartment, Lamia promises to help Sara solve the mystery of the missing children in exchange for her aid in escaping her stone prison. Will Sara be able to help Lamia and discover the mysteries of Cellestria, or will she succumb to madness?
