Lemuria.

Lemuria sleeps beneath the sea
A mountain peak submerged
Temple columns toppled
Vined in seaweed
See Neptune overthrown

Blue hair floats up to greet the sun
But the sun is failing in the deep

Fish will swim
Where Gods have walked
Step by step in whale song
The greatest people that ever were
With hair as blue as the sky
That they loved
With eyes as blue as the ocean
That killed them

Caught in a suffocating light
Rubble from ages gone tells tales

Tales of woe
And a greatness lost
Beneath the waves
