Scariest Thing In All Of Tolkien's Creation...Ever

[Rune Son of Bjarne]

The ringwraiths is by far the most scary creations ever!
Well, actually it is the black riders I find scary and not the consept of a ringwraith.

What I find scariest is when they hunt Frodo, especially when Frodo and friends look up the hill that they came from and see a black rider on the top. That always make me look over my shoulder. . .half expecting to see a cloaked figure standing behind me.

Ungoliant - the evil spirit & queen of the Giant Spiders that roamed Middle Earth.

I am not keen on spiders in the real world at the best of times, but given how Tolkien describes the Great Spiders from The Silmarillion, that even the great Melkor himself feared her and ultimately suffered her wrath.

I think of Shelob, but on a much more greater, more terrifying scale than the spider that attacked Frodo. Ungoliant is like my worst ever nightmare, a nightmare that lasts a lifetime of unwoken dread & fear
