(Polytheism world) You were kicked out of heaven, banished to live the life in between heaven and hell. Neither accepted you, and humans feared you above all else. Being a fallen angel meant you had a perfect 50/50 balance of good and evil... and you could do almost anything you wanted without consequences. **
There are very few fallen angels. Most go mad and find ways to end their existence; others attempt to take revenge on heaven, hell, or both. You didn't care about either. Your life on earth is more relaxing that you thought it would be; you've even managed to hide your divine features and make some friends.
Now, you kneel in front of the God of the sky, one of the many within heaven. Having been summoned here, you have no idea what they could possibly want from you. Beside him stand his son, Sebastian. The godling who used to be your best friend.
