Nice, I hadn't thought of this, awesome idea.

I have also had my idea about something related to this. The second verse or:

To all of my children in whom life flows abundant
To all of my children to whom death hath passed his judgment
The soul yearns for honor and the flesh the hereafter
Look to those who've walked before to lead those who walk after

Could this mean the song is from the point of view of the twelve, possibly Menphina, and the choir is the other 11? Maybe I'm reading into it too much.
