Azathoth

"Outside the ordered universe is that amorphous blight of nethermost confusion which blasphemes and bubbles at the center of all infinity—the boundless daemon sultan Azathoth, whose name no lips dare speak aloud, and who gnaws hungrily in inconceivable, unlighted chambers beyond time and space amidst the muffled, maddening beating of vile drums and the thin monotonous whine of accursed flutes."

- H.P. Lovecraft Azathoth is one of the Outer Gods of Lovecraftian mythology and as such is regarded as a cosmic deity of colossal proportions - beyond even the power of the Great Old Ones such as Cthulhu - and is the most powerful being in Lovecraft's Cthulhu Mythos. Azathoth is seen as all-powerful but not necessarily all-knowing (Azathoth is actually a "Blind Idiot God"), the trait of being all-knowing is said to belong to its fellow Outer Gods, Yibb-Tstll and Yog-Sothoth.

History
According to Lovecraftian mythology Azathoth is the omnipotent "Blind Idiot God" or "Nuclear Chaos" - it is said to be stuck in an endless slumber and is served upon by countless lesser deities that play a maddening tune on innumerable drums and flutes to keep Azathoth from awakening, for if the great "Daemon Sultan" should awaken even for a few moments all of existence is said to be doomed as it will signal the ultimate destruction of existence as we know it.

As well as its innumerable drummers Azathoth is tended upon by horrendous dancers and is said to float in the very centre of the universe in the centre of chaos itself (and hence "nuclear" may actually refer to its dwelling at the nucleus of the universe), no mortal has yet entered this realm and survived and judging by the visions spoken of by H.P. Lovecraft and later writers it is doubtful that any who did would wish to continue living, as Azathoth held the same insanity inducing aura as the other Lovecraftian horrors despite it being trapped in slumber.

Description
Azathoth's precise appearance is only hinted at throughout the Mythos, and indeed may be unknowable by mortal beings. It is described as occupying a position outside of the universe, where it is attended by a cohort of alien servants who continually bathe it with the sounds of pipes and drums. Though it is the ruler and creator of all existence, it is described as "a blind idiot god," oblivious to the universe and the beings within it.

​Powers
Azathoth is technically "God", and additionally a "Blind Idiot God" who is absolutely mindless and unconscious, but is omnipotent and the most powerful being of all. He created all of existence as part of his dream and is not even aware of it. Should he awaken, all of existence would be no more and all would once again be Azathoth. He cannot be destroyed as the concept of destruction is merely his dream, and he exists beyond the concept of speed, strength, mortals and the Outer Gods as they are all merely part of his dream. Despite being Mindless, Azathoth does have a will of his own and commands his messanger and avatar, Nyarlathotep. Proof that all of reality is merely Azathoth's dream: XXII. Azathoth 

Out in the mindless void the daemon bore me,

Past the bright clusters of dimensioned space,

Till neither time nor matter stretched before me,

But only Chaos, without form or place.

Here the vast Lord of All in darkness muttered

Things he had dreamed but could not understand, While near him shapeless bat-things flopped and fluttered

In idiot vortices that ray-streams fanned.

They danced insanely to the high, thin whining

Of a cracked flute clutched in a monstrous paw,

Whence flow the aimless waves whose chance combining

Gives each frail cosmos its eternal law. “I am His Messenger,” the daemon said,

As in contempt he struck his Master’s head.
