[Rune Son of Bjarne]

There is many scary charachters in the book so it is hard to point out the scariest one, also because you learn more things about some of them as the book progress.

Personally I found the Nazgul very scary when we only knew them as black ridders that constantly showed up behind Frodo and Sam. . .they really creeped me out.

Another charachter I found scary was Old man willow. . . you could do nothing against him, if you tried to hurt him he would crush your friends and if you did not then he probably would anyway.
