Chaos is the opposing universal force of Creation. While the term chaos often gives the connotation of disorder or confusion, the nature of the Chaotic force is more than that. It refers to a malevolent energy bent on unraveling the natural balance of life through destruction and consumption.
Chaos and Arweinydd
Chaos often adversely effects the Arweinydd, causing them to twist into a Chaotic form that seeks the destruction of living worlds. An example of this is the transformation of Zerom into Zeromus in the BS Dimension. Chaos takes over a host Arweinydd and eventually distorts the will of the Arweinydd until the spread of Chaos is their only desire.
Residue and Hosts
The force of Chaos can also distort and infect locations, leaving areas corrupted and unable to recover from the Chaotic destruction. Chaotic residue can also linger in an infected area and infect other potential host creatures even centuries after the original damage was done. An example of this is the destruction of the city of Nefol.
While Chaos is usually considered wild and beyond control, there is one known incidence where the host has been able to focus and use Chaos beneficially. After KoGuRai was restructured and became the host for the Nefolian Chaos residue, he was able to train and learn how to command the Chaos, despite being the vessel for the energy.
