I have just seen a few clips from Penny Dreadful, and saw this opening to one of the episodes
Man! That thing screams "DOSKVOL" from the top of its lungs. Especially the line
'Cause once this land Was heaven on Earth
Green hills were all You could see
But now it's soot And steel and brick
So it looks more Like hell to me
It seems even more topical if you look at it from the point of Belle, that is looking for the heaven in the form of her ghost belonging among Reconciled. On one hand, I might be stretching, because who in the brutal world of Blades would still even want to remember how world looked like before cataclysm, and with all of its vicious ghosts and uncaring deities managed to sing about God that takes you to heaven.
On the other hand, I remember that @AnneMunition said, that in her mind she thought about Belle as 'this good person that doesn't belong in this world ', so maybe it would actually fit :)
