Angels as a race.

To avoid duplication, I suggest naming the hero type Archstrategos (another name for the Archangel Michael, specifically his title; in translation from Greek, it means supreme commander, essentially the leader of the heavenly host). The heroes themselves could be named Michael, Gabriel, Raphael, and we'll need to consider the remaining names. Since the Book of Revelation mentions seven archangels standing in the presence of God, although all agree that three of these seven are Michael, Gabriel, and Raphael, the identities of the others are a matter of debate. Possible candidates include: Uriel, Raguel, Zadkiel, Sarachiel, Remiel, Anael, Oriphiel, Uziel, Raziel, and Metatron.
