It is the year 2072. A massive fission reactor explosion has wiped out the entire human population. That reactor was the single most powerful thing in the entire galaxy, and its explosion didn't only destroy humanity. The energy released by the reaction has blown holes in the fabric of space and time, warping the entire universe. Other universes, once located trillions of galactic years away, have been thrown about and stitched into this one, allowing strange things to seep into our atmosphere. With nobody else around, no single organism to help you... How will you rebuild the universe?
