In my story, all beings on the planet (and most all outside of it) are essentially infected with extraterrestrial, mutualistic parasites called souls, named so because they function similarly and are interpreted in similar ways to souls of the real world. A WIP summary of souls and their most common strain: Souls: Organisms from an unknown, alternate dimension that crashed into planets by comet. The soul inhabits a body as a host, but depending on the strain, will act differently on contact. Blue Soul: These souls simply enter the body and reside in the heart (over generations, the organism evolves to develop a fifth chamber in the heart specifically for the soul), where it feeds soul essence into the bloodstream so that it may be distributed throughout the body. The result is a symbiotic relationship between the host and the soul, where the host keeps its consciousness and has its body monitored and maintained by the soul, and the soul receives its nutrients and maintains its health in the host's body. TL;DR: Everyone in the world has superhuman vitality and physical potential, and a conscious immune system, as well as insane regenerative properties. The reason I bring this up though, is because the soul can not only repair the body, but reshape it. This is rare outside of zodiacs, which also have a WIP summary: Zodiac: An immensely powerful being of unknown origin, creating an almost godlike figure. A zodiac is a soul that resides in an enormous crystal, which itself resides at the core of a constellation’s brightest (typically) star. The soul uses the crystal as a catalyst for magic, and the star’s immense heat as an energy source, allowing for almost unlimited spells of incredible caliber. The soul synthesizes objects inside the crystal, mainly soul mirrors made out of an unknown substance, that allow the soul to project its consciousness through space and time. Through this process, the soul’s mind takes on forms in alternate timelines by possessing hosts and acting through them. The hosts are expendable; if the host dies, the soul cuts its ties with the body and proceeds to possess another host, usually on a near identical timeline to limit variability. TL;DR: Zodiacs are souls without hosts that project their consciousness through space and time to possess empty or currently inhabited bodies as temporary, expendable hosts. If you read the TL;DR's, you should get the gist of it. Now on to the real topic. Some more tame examples are: if an arm is stuck somewhere, they can force the muscles to break the bones for flexibility, before putting them back together shortly after; in combat, if someone is just out of reach, they can dislocate the joint for extra reach, then realign it in an instant. Another thing to note is that pain is repressed significantly in most cases, usually proportionate to the amount of damage able to be sustained by an individual before it becomes a threat. Additionally, pain can be suppressed manually to a degree if the host (or the soul in the case of a zodiac) wills it. Now on to the zodiacs, featuring Leo, Virgo, and Gemini. Leo: A lion-like man, very much like Hashmal from Final Fantasy XII. His main attribute is that he does not have joints, but rather gatherings of fluid muscle that push and pull with extreme force. This allows him to bend his arms, legs, neck, and even spine in any direction he pleases, without sacrificing force or vigor. Virgo: Virgo's body is made up of a viscous liquid with a thick, malleable membrane. She inserts bone shaped objects into certain parts of her body (limbs, spine, head, ribcage, etc) to give structure and a more humanoid appearance. The bones are made of a material that can be made flexible through use of a spell by runes. Her face consists of two eyes that float in various positions on her face, however she occasionally retains its form like a standard face, forming structures like a nose and a bulge like the shape of lips. Gemini: A single, werewolf-like body housing two beings: Pollux and Castor. Their body is split vertically down the middle by a fleshy line of tendons. This separates their left side (Pollux) and their right side (Castor). Pollux’s fur is a light yellow color, while Castor’s is a grayish black. The two think and act independently, but only on their specific side. When one is exuding more “power” than the other (power can be affected by a multitude of things), they begin to temporarily reshape the line so that their side encompasses more of the body. For example: if Castor exudes enough power to extend his territory to Pollux's arm (the body's left arm), he will have control over that arm. Each side’s head and face cannot be taken over or influenced by the other, meaning their consciousnesses will always remain separate and independent. When this power imbalance equalizes itself, the border returns to its normal position. I feel like I made this too long, but I didn't know what was more important than what, or how to summarize it further than this. So anyone who has the time and/or patience to read it all, please judge me and tell me how to be better at forum posting. It'd be deeply appreciated. Also let me know your thoughts on it (the concept in the title), or any ideas of your own that may coincide with the topic or grant inspiration.
