Chaos is not “natural”. It entered the cosmos through the cracks in the universe caused by the Gods War. Chaos does not recognise or acknowledge the limits of the natural and moral universe. As one put it, Chaos wants to be in the world, but not of it.
This understandably terrifies the beings that uphold the natural and moral universe. Rashorana went about calming the frightened gods, teaching them to be unafraid. Three who found that they were unafraid discovered that they could use the fears of others to their own ends. One of the first things they did was destroy Rashorna to keep her secrets to themselves.
These murderers were the Unholy Trio. They joined together and perverted their natures to make their weapon of hatred and vengeance. They wove a great magical ritual of potency far greater than anything before accomplished, for they had discovered the wonder and power of Primal Chaos, and used it to magically strengthen themselves for what was to come. They then engaged in their rituals of Chaos-birth.
The product of the ritual was Wakboth, the moral evil of the world. This senseless and terrifying entity is caused by wanton disregard for life, and he supports continuous brutal destruction. Twisted and foul, Wakboth is the world defiler. His existence was pure insult, since the world was doomed anyways, and he worsened the pain for all involved.
Kajabor was another major Chaos entity whose appearance coincided with Wakboth and the two are often confused with each other. Kajabor wields entropy in the world. Often called God-Killer or Black Hole or Great Fear, he destroys all vestiges of matter or energy, annihilating all possibilities of individuality or unity. Entities slain by Kajabor have never returned, and often even their names have been lost after being pulled from the universe.
After defeating the gods and destroying the world and its people, Kajabor and Wakboth began to devour each other. Prevalent belief says that Kajabor was killed by Wakboth, leaving the world defiler to face the Storm Bull and the god of entropy to face the forces of the dead. This theory has much strength, since the mundane world (reconstructed later) is usually held to be the origin of immorality, while the combination of entropy and existence created Time, which now rules the cosmos.
Kajabor is the Great Fear, and this motivated people and gods to follow such corruption as Wakboth. For this reason, Kajabor is as much the enemy as Wakboth, even though it is utterly impersonal. Wakboth offered immense advantages to his followers and many turned to Wakboth’s ways for their selfish ends (such as Vivamort, Seseine, and Bagog). Other Chaos entities invaded through the cracks in the broken cosmos, such as Krarsht and Tien. The conquered areas of the world were filled with slime and joined the malevolent ooze known as Pocharngo the Gorpgod.
These notes are to remind people what Chaos is, why the gods and people understandably fear it, and why Kajabor and Wakboth motivated a few gods, such as the Lightbringers, to take heart and attempt the impossible. When we think about the Greater Darkness, this is the background – the victory of Wakboth and Kajabor over the gods and mortals.
But also within it is the possibility that Chaos – defined as that unknowable stuff from outside of the cosmos and not of it – is not necessarily to be feared. The unknowable allows the impossible, and it is not necessarily moral evil or entropy.
However, the Unholy Trio show us that removing the fear of the unknowable can lead us to far worse evils. Again not necessarily, but one must acknowledge that is present as well.
