What are dreams? Some think they are figments of our mind. But what if they were wisps of a distant, magical world... a world you could visit? Twins Cade and Tasha discover Dream, the land dreams come from. It is a realm of misty forests, of verdant mountains, of mysterious gods who send dreams into our sleep. Cade and Tasha seek solace there; they are refugees, scarred and haunted with memories of war. In Dream, they can forget their past, escape the world, and find joy.

Phobetor, the god of Nightmare, was outcast from Dream. Now he seeks to destroy it. He sends his monsters into Dream, and Cade and Tasha find their sanctuary threatened, dying. To save it, the twins must overcome their past, journey into the heart of Nightmare, and face Phobetor himself.
