The 10th Branch
Humanity told stories of things that shouldn't be ever since they learned how to speak. Things that break the rules of reality.
Turns out, not only they exist, but their wrongness can be harvested and used as a power source. The most efficient power source known to man. Whole industries started to grow around harvesting it, and soon, a few megacorporations completely took over this business.
Some of them focused on "collecting" the Wrong beings. Others decided to create their own Wrongs.
Only 20 years ago, a new corporation showed up. The 10th Branch. Instead of gathering Wrongness for themselves, The 10th Branch focuses on cleansing or capturing the Wrongs and selling some of them to the highest bidder.
