Oglogoth

Found in Rose's Grimoire for Summoning the Zoologically Dubious. The Grimoire describes him as "OGLOGOTH, THE DEEP ONE. Whenever he grinds his teeth, all the children of a random galaxy somewhere will frown continuously for a nine thousand year span. He is the first and smallest of the SMALLER GODS, appointed in servitude of a vile, unfathomable pantheon of MIDDLING GODS which caters to the whims of the NOBLE CIRLCE OF HORRORTERRORS, an omniscient, omnipotent order of the elite few, forever cloaked in the darkness of the FURTHEST RING."

He dwarfs Nrub'yiglith, who in turn looms over Fluthlu, so the scale of this creature is near inimaginable. Good thing the Grimoire is in the hands of a young lady with such a good head on her shoulders.
