I am Yosef Mengalus, a dark mage who specializes in the manipulation of souls. A human soul is essentially raw mana condensed and shaped into form held together by various spiritual components. This soul is eternal, and carries on to the afterlife after the death of the individual. Through ancient methods, a living body can be deconstructed to expose the soul, which can be unraveled into its original state of raw mana and its other basic components. This provides for a large amount of energy and power, which has many applications, such as a continued supply of energy or weapons of mass destruction. To accomplish this, I have built soul extraction chambers around the country. Individuals are forced into the chamber and dissolved, allowing for their soul energy to be harvested for future use.
The problem is that soul energy is very unstable, leading to a short half-life. After the soul is broken apart, it tends to decay rather quickly, becoming completely worthless after about 30 minutes. This prevents it from being a reliable source of power. It is also radioactive in this state, which is a danger to other beings exposed to it.
I need a permanent way to keep the elements of a soul from decaying so it can be stored long term for future use, while providing protection from the radiation that it gives off.
