Somewhere else is a strange dimension that is accessible though the Anomaly. It seems to be 5 dimensional, with one thing being the same as everything, and everything being the same as one thing. It doesn't really apply to the real world. Everything is chaos and lights and colors and freedom, but the human soul cannot withstand the chaos after being used to order and science for so long. Two people have visited this dimension, both managed to escape. One was the NP, and one was the person the NP rescued from limbo.
