The King Beneath the Mountains was a song sung by the people of Lake-town upon the arrival of Thorin Oakenshield and the Company. It was a prophecy made after the fall of Erebor and Dale about Thrór and Thráin.
The King beneath the mountains,
The King of carven stone,
The lord of silver fountains
Shall come into his own!
His crown shall be upholden,
His harp shall be restrung,
His halls shall echo golden
To songs of yore re-sung.
The woods shall wave on mountains
And grass beneath the sun;
His wealth shall flow in fountains
And the rivers golden run.
The streams shall run in gladness,
The lakes shall shine and burn,
All sorrow fail and sadness
At the Mountain-king's return!
