Azathoth

According to horror and science fiction literature accounts, Azathoth is "the prime mover of chaos, the antithesis of creation, the foolish sultan of demons; he who gnaws, groans and drools at the center of the final void" or rather as "the center of the universe".

This cosmic entity is described as a colossal, chaotic and formless mass; even the universe itself is part of its essence, and the simple fact of staring at it would mean a death of horror and extreme madness.

A curse has made him a blind and lobotomized god, who spends the eternity of his imprisonment moving ceaselessly to the tune of flutes, drums, and other cursed musical instruments.
