This is the Edge. It is somewhere, yet it is nowhere. At the Edge, reality and existence are warped and lost...This is a place where proportions are contorted and everything you believe in changes. It is a sorrowful creature that feeds upon those who are lost. It is the hunter and souls are its prey!
This is a being that has resided at the Edge without hope of escape. What would one be escaping? After overstaying his welcome, he is now a victim of the monster that once seemed dead and lifeless...a rock and pond in a non-existing space...
NOTE: This in a way symbolizes life and death. Light from dark. We all spend our time here on Earth, but we might find ourselves wandering in a dream...and never return. In the main photo there were two floating lights that were made of vegetation. This shows that there is light on one side, but not the other. The minifig's legs have turned the color of the Edge and everything else beneath it.
This is a previous victim. The Edge is feeding on the being's intelligence (hence the brain).
