Seek for the Sword that was broken:
In Imladris it dwells;
There shall be counsels taken
Stronger than Morgul-spells.
There shall be shown a token
That Doom is near at hand,
For Isildur's Bane shall waken,
And the Halfling forth shall stand.
Called so because its allure prevented him from destroying it, leading to his death, and the lingering power of Sauron in Middle Earth.
