[@The Seraphim]yep.  My two versions of angels, Seraphim and Cherabim, were either sent to earth to be tested (all of them have to go through it sense Lucifer's rebellion) or the descendants of them.  Seraphim are fighters and Cherabim are support (non-comms, healers, entertainers, functionaries, etc.).  Seraphs tend to be logical and always honest, Cheribs are honest, but more emotional.

You can always have your own form of these (maybe an outcast clan/tribe) or make your own version up.
