Sky-high above, where only few would go
An ancient relic's hidden deep in snow.
It's guardian, once potent, is now lame
And long forgotten is for all his name.

 

Not everything we hide lies far away:
This one is very close for those who pray.
From up there you can see the sieges go
And all the nightmares hidden deep below.

 

Remote is not abandoned, as you see
Good gardening and care is the key.
And nothing in this world can bother you
When Cruma tower is your window view.

 

Long time ago it was a crucial site
When those who now live peacefully would fight
Though now the war is over, so is hate.
The long-forsaken sentinels still wait.

 

There's so much liquid that you forefeel flood
Not only water, though, but also blood.
Behold, as you'll be slowly passing by
Eternal sunset on the gloomy sky.
