So passed the sword of the Barrow-downs, work of Westernesse. But glad would he
have been to know it's fate who wrought it slowly
long ago in the North-Kingdom when the Dunedain were young, and
chief among their foes was the dread realm of Angmar and it's sorcerer king.
No other blade, not though mightier hands had wielded it, would have
dealt that foe a wound so bitter, cleaving the undead flesh, breaking
the spell that knit his unseen sinews to his will.
