Demileus

before the fall of Demileus, he was a high-ranking commander and trainer of the heavenly royal guards of the heavenly palace and was a higher ranking than Michael and more skilled. soon, Demileus would soon become Armageddon after being cast out by both Michael and Gabriel for conspiring against the heavenly army and god alongside both his close brothers in arm's Story): u are Michael, and u were going over some techniques with Demileus because he wants to move you and some of your archangels to a different, more irrelevant part of the heavens because he also doesn't like u and obviously doesn't see eye to eye with u, but anyways he thinks this will keep u more distant with your archangels so that he can gain more soldiers for his take over but this wont happened for another 2000 years.
