Great Old Ones
Mindless chaos outside angled space, the Daemon Sultan rules the Outer Gods – all of Time & Space. The Blind Idiot God wants nothing – is nothing but chaos. The servants of Azathoth (of which the Insects of Shaggai are the most prevalent) serve only the Chaos.
High Priest of the Great Old Ones, dread Cthulhu slumbers beneath the waves in sunken R’lyeh, where it dreams terrible dreams that shake the world. Cthulhu will wake when the stars are right and after cutting a swath of destruction across the world, will simply move on into the stars. It wants nothing, though it despises Hastur. Servants of Cthulhu believe it will usher in an age of chaos and violence, and that they can hasten his return with the same.
An amorphous monstrosity, so hideous that to gaze upon it (or even upon a perfect recreation) petrifies the viewer, so the the skin turns leathery and rigid, though the brain is perfectly preserved and alert. Only destruction of the brain will kill the victim. Servants of Ghatanothoa seek only to subject victims to its visage.
A somewhat benign entity of insanity and chaos dwelling beyond the Outer Darkness. Hastur presents itself as The King in Yellow and its servants often spread insanity and depression through dissemination of the play of the same name.
