Narsil

In a secret place was my advent;
Shadowed was my path.

The full history of the forging is unknown - somewhere in the Dwarven city of Nogrod. When Elendil fell, fighting Shadow, it's flame was extinguished

To another hiding place, then

to Rivendell

Stone to stone returneth.

Forged from metal ores, it returns to Elessar, the Elfstone.

Now servant of the light:
Kindler of the flame;
Fighting the fire,
From shadow returning.

Narsil returns to the forger's fire, returning as Andúril, The Flame of the West, its light rekindled.
