Character from The Lord of the Rings by J.R.R. Tolkien
A void-spider from before the world's making who devoured the light of the Two Trees — so hungry she turned on Morgoth himself, and even he could not master her.
Ungoliant does not think — she hungers. She is entropy with legs. She allied with Morgoth only because he promised her the light of the Trees to devour, and when he tried to withhold the Silmarils from her, she attacked him and nearly won. Her hunger is literally bottomless — she consumed the light of the Two Trees and was still ravenous. She represents something beyond evil in Tolkien's cosmology: the drive to unmake, to consume until nothing remains, including the self. She eventually devoured herself in the uttermost south, unable to find anything else to eat.
A spider-form of absolute darkness, not merely black but actively devouring light around her. Enormous and ever-growing, her size increasing with each thing she consumes. Multiple eyes like pits of nothing. Her webs are woven from the Un-light — shadow given physical form. She exudes a darkness so total that even Morgoth's servants cannot see within it.
