Underground life

Centuries ago
A dark castle stood
Under it's frozen ground
There was a secret dungeon

At the end of long corridors
what the noise of the world
doesn't reach
A weighty iron door stood
The dungeon door in the blackness
Is closed by strong chains

Heavy stones stretch dumbly
They watch in darkness haunting souls

Who known everything
But anyone knows nothing about them

And who lived in the castle
They are already dead

But under the ruins
Deep in the dowels of the earth
The black stones immovably
Keep their dark secret

Anyone knows nothing about them
But they know everything
