I'll add my two additional Battle roles to this list:

6. I was born a deformed arial and sent on a hopeless mission to the underdark with other-unwanted nestlings.
A bunch of bad shit happened and I ended up with a magical spider inside my head that made me crazy. (Eck)
I won a role contest for this one.

7. My life was hellish as a curiosity plaything of the Chessmaster.
One day Villagers showed up and killed everyone. I followed them back to the Village.
By my seventh Villager even I was out of ideas for hating magic, so I went with the "I Love The Village" as a
role, which worked out really well and ended up being one of my best characters ever. (Mauz)
