Like the most commenters, I believe this song is about the leaders of Christianity.
Also I would like to add that the lyric
"castles of self-righteousness built on graves"
could also refer to most early churches being built right on top of places where traditional Germanic/Norse deities were honoured.
The lyric
"The dynamo of a northern golden age
Darkened our future, blinded by greed"
could in this context also refer to the same thing, the Germanic/Norse belief system crushed by Christianity.
