Sooo... His name is not Lucile, but "Luciel", the "Light of God."
It's a weird combination of Latin and Hebrew that's been around for a long time. Sometimes used to refer to Lucifer before the "Fall," neither Luciel or Lucifer are actually used in any Hebrew texts. The angel referred to as "Lucifer" was called "the shining one" or "morning star", neither of which are an actual name. The name "Lucifer" was coined by the translators of the King James Bible, since it was the Latin name for Venus, the "morning star."
