Ahmuin was a legendary Elven adventurer from the later years of the Dragon Wars. Though she accomplished a number of things during her adventures, it was the slaying of the great red dragon, Azudin the Invincible, that cemented her fame. Though she and most of her companions were killed in that epic battle, so was the dragon.
According to legend, it was with this arrow, that Azudin the Invincible, was felled. The legends say that it is a magical arrow, able to slay any creature it strikes.
