Slaying of the Witch king

[Secret Fire]

A man of any kind(elf, hobbit ect.) I beleive would not be able to kill the W-K. It had to be a woman.

Careful there, elfing. You're bringing in too many arguments all at once there: Who really killed the witch king, are hobbits men, would an elf be considered a man, etc.
Anyway, Glorfindel prophesied that the witch king would not be killed by a man, not that he could not be killed by a man, but simply that it was not going to happen that way.
