Within you, the manifestation of all the evils of the world lay. From sickness to cruelty to arrogance and even pain, these manifestations hold great power and yearn to be free to cause mayhem and suffering. You are their prison, and they want out.
These manifestations will torture you, force you to suffer their evils, and attempt to bribe you to release them. Any ordinary man would break after suffering this for more than a second, but you do not, thanks to a single manifestation’s help, Hope.
As long as you do not give in to despair, as long as you have hope, you can carry all the evils in the world. With time, you can learn to control them and wield their great power. By understanding each manifestation, their concept and powers, you can slowly gain control over them. In time, you could even devour them, taking their concept for yourself and gaining full control over it, although this would take dozens of years just to do one single concept. It is also possible to make deals with them, borrowing their power in exchange for fulfilling a desire of theirs. You could use them for destruction, or perhaps use them for good, as if you control "pain", you can take it away just as easily as you can cause it.
Do note that if you ever succumb to the evils and release them, not only will you lose their power, but you will also cause the end of the world. It could take a few years, but the world will end as they run rampant.
