The story
Born wingless and blamed for the end of the world.
Cassia was mis prophesied as a doomsday omen at birth and handed the role of scapegoat for the fake princess Celine, then abandoned by her own father. Her adoptive father keeps her alive long enough for the legendary divine wings to wake in her. She proves Celine is the real destroyer behind all of it, brings down the corrupt Wing Caste system and takes the throne herself.
