Previous definitiona are correct, but also, i have one fact to add. It is believed that weare all simply part of Azathoth's dream, and were he to wake up, we would all cease to exist. Othe theory: When he awakens, he will order Nyarlathotep (messenger god) to destroy the universe.
Azathoth: *wakes up*
by GreenEmu June 07, 2005
Chief deity of the "Cthulhu Mythos," worshipped by lesser deities and servitors in the Lovecraftian pantheon; described as having an anamorphous body that constantly writhes and undulates to the piping of a flute; also described as being the essence of all physical mater in the multi-verse.
"...the boundless daemon sultan Azathoth, whose name no lips dare speak aloud, and who gnaws hungrily in inconceivable, unlighted chambers beyond time amidst the muffled, maddening beating of vile drums and the thin monotonous whine of accursed flutes." - H.P. Lovecraft, The Dream-Quest of Unknown Kadath.
