The sky is covered by thick black clouds created by the humans in an attempt to cut off the -----------' supply of solar power. The ----------- responded by using human beings as their energy source, later growing countless people in pods and harvesting their bioelectrical energy and body heat. The world which humans inhabited since birth is the X, an illusory simulated reality construct of the world as it was in 1999 developed by the machines to keep the human population docile in their captivity.
