Rosiel was once the brightest angel in Heaven.
He ruled with kindness and fairness, with reason and integrity, and listened to the voiceless and the downtrodden with compassion. But, thousands of years later, all that was once pure and good has become twisted: he can be cruel to those he loves, and affectionate to those he tortures, he can show great loyalty through betrayal, and great love through destruction.
