Azrael hadn't been wanted since the day he was born. How did he know that?
His mother had dropped him off at his supposed father's 'Training Grounds,' without even a note. She could have at least wrote, 'You will be better off with the Emperor, looking out for you! Love Mom.'
When the entire planet fell under attack by a new guild hungry for power, he was rescued by a few of his father's trainers. Now, he begins to believe they only took him on for the power he was supposed to inherit.
Too bad it doesn't exist...
