Ungoliant stopped dead, and there was a long and empty silence. Then, slowly, she emerged from the dark to stand before the elven lord. Huge and menacing, she placed each of her great limbs in front of her as slowly and deliberately as if she were cranking back the cord of a crossbow.
Eventually, when stood scarce a stone’s throw from her foe, she reared up to her full height. Her great fangs, like swords in their own right and dark as dried blood, flashed out, and when she dropped down again her limbs ripped boughs from trees with the force of their downward travel.
"You dismiss me with a bravery you do not feel," she cried. “I am no mere spider to be dismissed with the swat of a hand! I have devoured the light of the world and reduced its walls to rubble, I have brough ruination upon the lands of the Valar themselves. Kings and armies have fled before me like ships before the storm. It was I who taught the meaning of fear to Morgoth Bauglir - I and I alone! I am Ungoliant! And you," - she leaned forward, letting the death-stink of her breath wash over the elf - “you had best remember that, for it is the last name you will ever hear on this earth."
As the great beast towered over him and the shattered trees to either side of her, Finrod quailed. He wondered, vaguely, whether he should run. But beneath Ungoliant’s gaze he was as a rabbit before a great cat, and his feet were frozen to the floor.
The sword and shield dropped from bloodless hands as Finrod stared into eyes that had seen deaths innumerable, and a small voice inside of him told him that this was it. He would be dead in less than a moment.
The stench of death was around him now and he was transported back do a dark cell with a hulking shadow pacing around him. This creature was much bigger than a wolf, by far. But there was a rational piece of his mind that still fought on, and slowly - as though his hands and arms moved through treacle - he strung his bow. I shall not go down without a fight, he vowed, I - who tore a great wolf apart with hands and teeth.
“You underestimate me, spider,” Finrod spat, “You underestimate me greatly. For I still know the songs of power, and you have nothing but your mass with which to combat them.”
