^I started to think about it like that too. The title took on a whole new meaning, their Seventh Heaven period was a fantastical paradise where they were above worldly concerns, and now paradise, their Eden has been lost and they must face the world for what it is. It's a longshot since I'm not quite sure how Red Moon fits in this theory but it's fun to think about.
Anyway, *really* low quality preview time!

How do you always manage to make me fall more in love with your voice. The song itself sounds so lovely and melancholy. Sure it'll be absolutely beautiful in HQ.
This song was previewed on Kalafina Club and apparently,
Eden was previewed last week but no links for that have shown up.
