Lucifer

His other "brother" is Raphael, who serves as something like a combat medic and healer in general. Belial, a female angel -- she has a "brother" of very similar name -- was among his followers gone to hell with him, and she loves him like a wife. He was ignorant of her affection when he was in heaven. His reasons for rebellion were mainly two -- first, he disagreed with God's over-restriction of angels relative to humans -- he wanted more freedom for angels. Second, he was smitten with Alexial, a female warrior angel, who was then with Azeigial. He would have married her too, but at the time, angels were not allowed to marry as humans do. Things have changed though regarding angels and marriage. Lucifer was and is noted among the angels for being strong, strategically brilliant, and charismatic. He is a survivor. Even in hell, he contended with some powerful demons who would have taken his throne if they were able. His plan of rebellion was not so much about a violent overthrow of God, who is quite powerful. Violence was used against angels who opposed him. He intended to get key angels behind him and promote a popular uprising that would pressure God to abdicate authority over them, since God is not exactly a tyrant as some suppose.
