What if there were two SCPs, lets call them Entropy and Extropy, that had to be kept together to prevent mass destruction of their surroundings? Entropy, when alone, would cause its immediate surroundings to crumble and degrade and rot and break, etc, killing people around it, and superheating everything to the point that atoms melt into a quark soup. Extropy would cause its immediate surroundings to organize, fortify, grow, harden, etc, to the point that it poses a serious hazard to people (imagine walls that grow towards Extropy, lack of friction on the floors, everything is at absolute zero). When together, the two opposites preserve things, keeping their surroundings exactly the same.
Basically, The two SCPs are the embodiments of order and disorder. Thoughts?
