Thorin had been lost in his own thoughts, and getting rather quite annoyed that they were being kept for such a long time over something that was not really a concern of his or any of his companions-especially since they did not know how much time they would have before others would try to retake the mountain too.

Elrond held his hand out curiously. "If you would allow me to look at it, I may be able to tell you more about it." the elf offered.

Forged in Gondolin, for the Goblin Wars of the First Age."
