At the beginning of Time there was only one source of Life that was Heaven, outside of our Gates there was nothing but endless Darkness in what resembled a endless Abyss.
Since Heaven was abundant in Life we had a great government similar to the ones that you humans have today,at the top of the Chain was our Father and King Yahweh,it was He who picked Twelve Archangels as His Personal Knights who upon being chosen received Power that was second only to Yahweh.
Each Knight was given a unique Title that identified us by our Role in the Kingdom of Light,my title was Threefold, Archangel of Death,Knight of the Enochian Magic,( this was a very unique form Angelic Magic that only Yahweh knew), and Archangel of Sacrifice.
My eleven brothers titles were different they were Warriors, Messengers, and Quester's, these titles allowed them to expand their roles which would allow them to come to the worlds man, which has not been created yet.
After us there was the Archangels that just came to the Twelve Knights with the running, worship,and anything else that they needed the Councils approval for.
Then you have the cherubs and serphim which were lesser Angels these also include the Cupid's. It was truly a great and blessed Kingdom until Yahweh had summoned the Council.
During the time we had Minor wars to deal with but other than Yahweh had pretty much gave the Twelve Knights the basic runnings of Heaven that is to a certain degree, were extremely respected by the others and so we ruled as we were instructed.
