The Energy Thread

So many things can be seen as a whole of woven threads.

— Unknown

Threads are a concept, a phenomena, something other and not quiet describable to fall into a category. They are responsible for forces that can be influenced by the creatures of the world and are believed to therefore be tied to an individual and their potential. All in all the one thing they all have in common is that they are invisible to most senses, only a select few can see some threads in specific circumstances.
Other than that, each Thread is best described on its own.

The Energy Thread runs through all living things that have a nervous system. It is believed to be the target of those that wish to effect the body for better or for worse. That is to say, magical healers appear to target this thread when another is ill or injured. While on the other hand, some beings have the innate or learnt ability to strike at another's Energy Thread for a number of effects, the most common being a vertigo-like stun or to cause one to fall unconscious. It is theorised that repeated magical healing and straining of one's body can lead to a strengthened Energy Thread over time, eventually resulting in a heartier individual than average - although it would be a fine line to walk if true.

Manifestation

The circumstances in which someone could see this thread within another is extremely limited, but it is on record to appear as a glowing bright tangerine coloured thread.
