It's the same as usual. 1. Angel's male or female, the spirit world, ( I rather call it )Angel Town outside of heaven on the clouds I call it. 2. Devils male or female, the underworld where devils reside. 3. The veto I rather not get rid of, Angel's and devils never buddies rather not change that. 4. On Earth in the spirit world angels and devils they attend college I rather say. 5. Angel guide their human up the right path or tempt if devil. 6. Humans alive can't detect angels nor devils in their soul form. 7. Angel and devils cannot love each other it's forbidden. Rather keep that you will understand later. 8. No breeds other than, human, angel, devil, witch.
Devils are wicked they somewhat the same as Satan's demons, they rule their side like a gang using, fear, rage, pain. The underworld is Gothic nice, biker gang theme, bars, rude behavior is rewarded but don't go to far rude because the adult devils are beyond painful and scary. Devils love being late, insults, carefree life to a long point. Devils and Angels are a ghost in the great beyond the unseen invisible world, to the living humans. Angel's and devils cannot die but they can feel pain like a chainsaw slowly cutting through them, they feel it then quickly recover.
Angel's live in the angelic realms outside heaven on the clouds, they all virtue, nice, sweet, Utopia up there, all the angels seem to be a dream come true as their way of life, saying all the right words. They cannot lie forbidden to, some of that Bible stuff still exist amongst angels and devils. Angel and devil tempt or guide their assigned human to make the wrong choice or good choice in life. Human makes good choices angel win, bad choice devil, win.
Also the veto, it's a cosmic power that prevents both angels and devils from making physical contact. Angels can become a devil or a devil become an angel, just a matter of leaving the low spheres for the high spheres to become an angel or leaving the high spheres government for the low spheres government to become a devil. Just be warned, if your devil becomes angel you must create a new devil as the tempter, same thing with angels in reverse. The college? I wish to call it Realm University on Earth. In the spirit world, the Angels and Devils school above the human's Realm University, as the human's school below. In the spirit world I want to say angels and devils age 1 year older every 1,000 earth years. Around 10,000 earth years is when angels start getting mature and devils get worst. I call these angels and devils that have males and females, as halo angels or horned devils, they the same size as human plus they have sexuality. Angels period are forbidden to mate with devils and humans it's a serious sacrilege. Devils are forbidden to mate with angels and humans to it's a serious sacrilege amongst devils too.
The angelic realms, the angels, don't allow the LGBT into their ranks, that's just something anything related to heaven would never allow. They still practice that dying to the flesh stuff it will never stop. The devils accept the LGBT though.
