After the defeat of the dark lord, Morgoth, and eventually his deadly apprentice, Sauron, the tyrannical disposition in the land of Middle Earth was no longer coexistent with any realm but that of the void, however, within the deep trenches of the earth, loomed an enemy unspoken of. In the creation of the earth, in which was originally a failure resulting in the metaphorical crumbling of its core.
A lack spiritual consistency and thus the perishing of his race, he created the four angels of the earth. They would be responsible for the spiritual spell in which will continue the original theme of the valar, sung in the creation of Middle Earth. However, this happened to be one of many themes Morgoth disrupted in an uproar of the chaotic theme full of hate, and discord.
The angels therefore turning into vile demons who wished to serve Morgoth in the preposterous conquest of Eru's realm. Eru rather than destroy them, bound the four demons to the beneath the earth, and cast upon them the curse of eternal slumber.
This resulted in the unfortunate fall of morale in the race of humans, and the disbelief of eru's divinity and existence. This then forced him to pass judgment on the race of man.
In the continuation of Morgoth's conspiracy, he chaotically tampered with the creation of the Dwarven race, casting upon them an everlasting greed and lust for gold. They dug into the deep bowels of the earth in search for more gold, awakening the four demons.
The four demons fled to the realm of solitude in which Morgoth had taken refuge, while building the mocking race of orcs. They awaited command, but the Valar took action more swiftly than anticipated by the Dark Ones.
And so the tale of the four demons begins, in their hidden plot of subterfuge, in thanks to the brilliance of Morgoth, the Lord of Chaos.
