As far as final editing for the character background story:
My comment is with the "life" and "death" classes. I would be careful not making their story background hint at being religious or 'abrahamic' (Christian, Jewish or Muslim). I would also strongly suggest not making the backstory of the "life" and "death" classes pagan.
Contrasts between light/dark, good/evil, truth/lies is sufficient on it's own. The more generic (and intriguing) the backstories the better. @ironshield
