Paradise of Angels

Anatomy and Rules of the World Hierarchy of Wings: An angel's power and rank are directly related to the number of wings they have. Common angels have one pair, while higher archangels have two, three, or more pairs of wings.
Angelic nature: They are immortal, not needing to eat, drink, or breathe. When wounded by ordinary weapons, they bleed, but to reach their true essence (ichor), special immortal weapons must be used.
Neutrality: Angels who refused to choose a side during the war between Heaven and Hell and went to Limbo will eventually begin to wither and automatically turn into demons, as Heaven's system considers anyone who disobeys God to be evil.

Key Characters: Lucifer (Samael / Helel) – formerly one of the chief archangels. He possessed an incredibly beautiful voice and a rebellious, proud nature. His unwillingness to follow the Father's strict rules led him to rebel.
Michael is Lucifer's older brother, a devoted warrior and the primary defender of God's plans. It was he who defeated Lucifer in the war and personally cast him out of Heaven, causing profound psychological trauma to both brothers.
Gabriel is the third-highest-ranking archangel, responsible for information and communications. He's a rather ironic, outgoing intellectual who's perpetually overwhelmed by heavenly bureaucracy.
Raphael is the angel of healing and leader of the heavenly choir. In the past, he tried to teach Lucifer how to play musical instruments and gently supported him, but later became afraid of him due to his brother's growing aggression.
Other angels - dozens of other biblical ranks are described in detail in the universe (Uriel, Jophiel, Barachiel, Zadkiel, etc.)

Relationships Between Brothers: Before Lucifer's fall, Heaven was a turbulent family: Michael and Lucifer: Michael is the older, responsible, and devoted brother. Due to young Lucifer's hyperactivity and whims, Michael often had to babysit him and control his behavior. Conflict: Lucifer constantly broke the rules of Heaven, looking for loopholes for fun, and ultimately rebelled, leading to his exile to Hell by the Father and Michael.

Rules and Atmosphere in God's Family: Heaven is governed by a strict hierarchy, with the Father (God) at the helm. "No Fun": Heaven in this AU is depicted as a place with strict boundaries, where mischief is not encouraged. Lucifer grew up there as the most restless and problematic child. God's Omniscience: The Father sees all possible outcomes of events, but, as the author jokes, deliberately avoids looking 100% into the absolute future so as not to "spoil his enjoyment" of watching the children.
