Nexus Threads

Nexus Threads(, Banshi) are sentient, metaphysical strands of fiber which can compose a multitude of weapons, life forms, and clothing. Rasetsu & Tenchi were made out of two Nexus Threads of an unknown being, literally being a mere sliver of that creatures power. The Nexus Threads are capable of drastically accelerating the evolutionary state of a species, but they are extremely dangerous, and quite easily capable of taking the life of a creature due to the sheer power that even a single thread holds. Because of this, they have been molded into clothing worn on the outside of a persons body.

Physical Appearance
In their most raw and basic of forms, the nexus threads take on the form of ifinitely small cloth threads which seem no different from the typical threads one uses to make articles of clothing out of. However, with one distinct difference, being that nexus threads are constantly emitting a bright red, ethereal glow from them. Nexus threads are capable of being woven into nearly any given conceivable shape or manifestation, hence why most people on earth have made them into clothing, but their constant glow is proof of their mystical and otherwordly powers which aly dormant within them just waiting to be tapped into by others.

History
Millions of years ago, when mankind was just taking their first steps out of the primordial darkness and into the light, a metor crash landed on planet earth. From the meteor hatched the original nexus threads which then branched out and proceeded to find a host with which they could establish a symbiotic relationship to. Nobody even to this date knows exactly where the nexus threads came from or who created them. Seeing the intelligent beings on the planet were humans, the nexus threads bonded with humans, but found that the symbiotic aspect of their own power made them almost incompatible with humans and other living beings due to the fact anything they attached themselves to perished almost instantly, being overwhelmed by the immeasurable power contained within the nexus threads. Instead, the threads decided to be worn on the outside of the human body, granting them power, but at a much less severe rate and lesser height. The nexus threads evolved the minds and bodies of humans and granted them the place of the most dominant species on planet earth.
