I'm kind of free associating here-sorry.

I'm reminded of the highest rating you can get for Kain in the original Blood Omen: Legacy of Kain game: 'Devourer of Worlds'. That would fit nicely for Eden. And remember that Cain was Adam and Eve's son.

I imagine that in turn was inspired the Hindu text that Oppenheimer quotes during the Atomic bomb testing : 'I am become Death; the Destroyer of Worlds'.

Maybe a little far-fetched.
