Yaggothoth

The Fallen Master, The Hopeless Tyrant, The Radiant Progenitor, the creator of the Yagathians, and possibly other life forms of the Yagathian Empire.

His power of manipulation and immortality became known throughout Yagathian mythology and was recorded in Eshermekite mythology.

Mythology
"'The Great Yaggothoth once ruled the Earth and was later buried in the ground and became one with the ground on which he ascended from and the tendrils of his power now influence and creates a dominion and more of his brood were left to rule the World'"

He was also known for his power of manipulating the Yagathian Empire into dominating the Earth and creating a "Perfect Race" to take control of the planet after the demise of his imperial rule.

Then he was opposed by the Astral Masters and became an enemy of them by rejecting the laws of the Outer Dimensions.

Yaggothoth tried to get redemption for his wicked deeds but was too weak for the temptation of power. He was cast in the Dark Abyss and became more hopeless and bitter.
