Why?
Ungoliant is, as I see it, older then the Elves. It's in a way the same category as Tom Bombadil. I mean:
- we do not know what she rightly is. Yes, I know, a Giant Spider, but is that all?
- we do not know when she was 'born' or 'created'
- we do not know what happened to her after she fled from the Balrogs
In fact we do not know anything for sure, except that she participated in the attack on Valinor in the First Age, and the tale around it. She may have spawned other Children in Avatar long before Shelob. I asked if that is mentioned in the Sil, for if it is, than these are some of the foul things Rimbaud means, I guess.
