I'd be happy to let you look over my work. Please let me know what you think. I put a lot of effort into creativity and flavor over power, so I would appreciate the feedback.
The very nature of an angel is an artificial being. An angel is not 'born', he is 'created'. And because the angel is 'created', it follows that he has a 'purpose'. He has a 'reason to exist'. Therefore, if an angel suffers, there is a reason for his suffering.
