My body, scattered in the universe Zack sent me to, seems to be lost. However, the increased mass in that universe (due to my ashes) tips the feeble equilibrium that existed before and quickly the universe starts to collapse in a big crunch (mmm,
chocolate - no, silly, the other
big crunch, how could I dare to advertise!!). Hence, the ashes of my body start to be closer and closer together (and since it's god mode in all posts), miraculously, and with a little help of my will, my body is recreated.
I'm able to escape the collapsing universe through the portal that sent me there just before the density becomes unbearable. By pure chance, the portal was close to the place where SteelFist's planetoid is, but I fail to notice that and I head back to Earth. The effect of the collapse of the universe I was in has its effects on our universe. In particular, the radiation that escapes through the portal in the final instants of the big crunch is, by far, stronger than any supernova. In particular, the huge neutrino emission close to the planetoid induces the transition of the neutrons in the iron atoms to protons, creating several radioactive unstable elements, for instance the radioactive isotope of Zinc:
56Zn.While the iron is disappearing, the carbon is also suffering the same fate, being transformed in a radioactive form of Oxygen:
12O.
Furthermore, the energy released ionizes all mater in the planetoid and is even able to get to the point where some nuclear fusion occurs that ends up absorbing part of the energy when elements heavier than iron are created. As you can see, it's evident that the big crunch of an universe is clearly more destructive than any magical spell.
So, back to what is important, there isn't much iron around anymore and not much carbon either. New elements were created and some radioactive oxygen is also present too. So, when things cool down, some very scattered bits of what hardly could be called "rusty fist" may be found.
Meanwhile, I arrive on Earth, I climb to the first hill I find and claim: my hill.
