"Tartarus" was exactly what I was thinking as well, I've heard some Turkish "Tatar" claim, but that makes no sense for something like As Nodt, or Bleach as a whole. And yes, the "-iel" is very common in Angelic names, but no one has found a linguistic source on the "Bisk" or "Griman" in the other two revealed names. All we know is what the Kanji says.
