A brief introduction to the nature of the astral planes, the discovery of these by the Viligoths.

Before the shedding of the vilii and the fythii, the only sentient being in the universe that can travel through time and space at will are the Iluvataris. Note that Elyohim is sentience incarnate, that his will is existence and proof of this is the universe.

With the shedding of the vilii, the morgoths, reptilian and insect-like creatures living in the dark side of the universe, who only have a vague notion of existence, and faint hint of conscious thinking, grew in cunning and dexterity, and became viciously aggressive towards each other.

The viligoths arose from the most cunning, and versatile vilii infected morgoths. Due to the barbaric nature of the morgoths of cannibalism, vilii essence collected to the surviving morgoth tribes. Subsequently,a creature born of pure vilii marked the domination of the viligoths among the morgoths.

Battles between viligoth tribes, resulted in a profound discovery of using the vilii essence to its advantage. Viligoths became faster, effective killing machines. Their mastery over the vilii grew as they discover more uses of it in the fields of decapitation, mutilation and embowelment.
As the viligoth's sophistication in using the vilii to kill grew. The Iluvatari resolved to put an end to the viligoths aggresiveness by Fythii. However, the fythii, had not cured the entire viligoth's barbaric ways, but enraged the race and united against the Iluvatari and the Iluvatarian allies. The viligoth's planets had been so drenched in vilii essence, exponentially increased through selective breeding, that fythii essence had solidified into corporeal forms, in globules like oil over water. This was among the greatest mistakes of the Iluvatari, for in their pursuit of developing barren worlds, they neglected the backwater ones where vilii had grown to an uncontrollable degree. Note that human beings would have turned out that way, if Elyohim had not intervened. Most of the Iluvatari harbored deep hatred for the humans because of Elyohim's special treatment of them*, and as a result, the vilii also had this ancient hatred.
