Here's the story for you;
There was a certain mad scientist who figured out how to animate the non-living; he had found out how to crack life's code. The universe planned for him to animate a Lava Golem and use it to conquer the world. If you were to read the timeline, you later find out that the Golem eventually turns on its master and its master is forced to kill it. However, a soldier from the war against the scientist got his hands on the scientist's time traveling device. He went back in time to the point right before the Scientist declared war and killed the scientist. The Lava Golem, which had already been made at that point, wound up killing the soldier in retribution for the scientist. The Lava Golem, now without a master, is free to do whatever it wants. It decided to cover the world in lava so as to make the Earth into a perfect place for breeding more Lava Golems; how would he do this? By entering an active volcano, getting into the Earth's core, and causing eruptions in every volcano in the world simultaneously.
The reason this would fall under the IPF's jurisdiction is the fact that there was no timeline in which the scientist died and the golem lived, thus, whatever the golem does, it will cause permanent and unfix-able damage to the universe. Where would the IPF confront the golem? in the middle of the wasteland that the Lava Golem was created in. There is an active volcano three miles from the Golem's current position. There are a few trees scattered around the place accompanied by a few bushes, but the land isn't right to support any but the most resilient life. Animals are scarce, but bugs are aplenty. LET THE BATTLE COMMENCE!!!
