Elven underworld, colours of the stars
Their dens seal the love
That lies above, elven underworld
So far from the stars
Their dens seal the love
For the night and the skies

Woods and wild, air and light
Bones of the earth
Crafted by the Dwarves
Legacy of Naugrim
[ Lyrics from: http://www.lyricsfreak.com/b/battlelore/thousand+caves_20871570.html ]
Caves of Menegroth, dwarven illusions
All the cold and grey, covered with green
Caves of Menegroth, dwarven illusions
Walls of golden fey, cover their realm

For once their eyes can see
The same harmony
For once not to care the race
Beards or ears, the brothers face

Hammers of Khazâd
Shaped the moutainside
Blasted like a lightning
The skill, the neat, the pride
Legacy of Naugrim

Elven underworld, colours of the stars
Their dens seal the love
That lies above
Thousand caves it's stalk
Cursed by Sindar
All the beauty's gone, under the waves
