Something I've noticed while playing around with the Grigori in debug mode was that Azazel still likes to play around with the mortals, i.e. he'll occasionally sire a nephilim.
While I'm here, let's compare what we have with
my predictions:
Azazel (death, maybe earth and blood)
Kokabiel/Baraqel (astral, maybe death)
Araqiel (earth, maybe astral and nature)
Chazaqiel (air, maybe water)
Shamsiel (fire, maybe astral)
Samyaza (because even though Armaros/Penemue has a more distinctive niche, Samyaza is too big of a name to pass up).
