Warning: this topic contains imagery that some readers may find disturbing. So in this universe that I'm working on, most living creatures have souls. Your soul basically acts as a battery for the rest of your body, providing energy that keeps all your organs running. (It also contains the various energies that make magic work, but that's another story.) Special channels that run alongside your blood vessels carry unique life energy from the soul in your chest (right next to your heart to be exact) to whatever parts of your body need it. Now, this begs the question: what happens if this energy flow stops? Well, this is most often caused by a deadly process known as "soul deconstruction," which in turn is the greatest risk of artificially fiddling with the contents of the soul. In this universe, pure magical energy does not follow conservation laws; it replicates itself and sends the new energy through the body. (This process is subconscious with life energy, and conscious with elemental energy used in casting spells.) If the soul becomes unbalanced, this duplication may stop, and all the pure energy will simply flow outwards uncontrollably. Normally, the energy flowing through the body's channels becomes diluted so that it doesn't damage your internal organs. During soul deconstruction, however, the energy flows too quickly for this dilution to happen. The main side effect of this is internal magical burning throughout the entire body, which, as you can imagine, is painful. Pure energy is HOT. It can eat through flesh like any strong acid in high enough concentrations. Luckily (or perhaps not so luckily), the energy channels in the body are not thick enough to allow energy through in such a high amount. So you survive. But not for long. All that energy has to go somewhere. The main exit points for the energy channels are in the fingertips, palms, feet, eyes, and mouth. Pure energy doesn't give off any light (it's basically invisible), but the heat released as it breaks out of the body does. Bright white beams of light, pouring from these extremities, charring anything it touches in about a three meter radius. (Past that, the energy disperses into the air and is no longer harmful.) At this point, modern medicine can still help you, but you'll be covered in burn scars for the rest of your life. And the process doesn't end there. Without a soul powering them, the body's internal organs begin to fail. All of your body's systems can store small amounts of energy for use in emergencies, meaning this process isn't immediate. The least vital organs go down first, followed by the most vital ones (which have the highest priority in emergency energy storage), ending with the heart. Of course, since the heart is still desperately pumping blood as the rest of the body fails around it, whatever holes your soul's energy poked in you earlier will be bleeding profusely. But once the heart stops beating, finally, mercifully, you die. Thanks for sticking with me. Now, what do you think about this concept? Are there any egregious holes in my logic? Any curiosities that I can sate? And I do have a specific question: what would the final part of the process -- where all the organs fail one by one -- feel like? Would it be painful? Or would you be dead to the world by then?
