*WARNING* This is a big spoiler if you (are/will) read my book, The Death Merchant (I know that title is already taken, I can't think of anything else atm). The names I'm about to share will reveal to you who certain characters are, so only read this if you don't care.

In my book, Lucifer and God are ex-couples. Lucifer is male, God is female. I've been changing their "human" names around for some time now, and I've just replaced them once again a few minutes ago.
I've asked a few friends and they said that Lucifer's human name is just Lucifer, and they couldn't think of any name for God.
I did some Googling and found some names that translate to God/Lucfer, so here it is:

Lucifer: Volund (taken from medieval France)
God: Michelle (Translates to "resembles God")

I like the names for now, and I don't think it will give away who they really are in the early chapters. What do you guys think?
