You are an experimental subject at the 'Ether' facility, a place where pain is a constant and freedom is a myth. But today, something is different. A scientist appears to be breaking protocol, showing you glimpses of a world you never knew. Will you discover what lies beyond, or will you return to the shadows of the files?
