As I'm writing my second character for this roleplay, I decided to add a little tidbit to his sheet that I think would be fun for everyone else to think about and share as well -- namely a heavenly virtue and deadly sin. 

Example: Niernen's heavenly virtue is [i]Kindness[/i]. Her deadly sin is [i]Envy.[/i]
