And basically there's an option to make player character vampire also... That could be one adventure seed. Character is turned into a vampire and he wants a cure! Some old tales tell that killing the master vampire will break the curse but what if after slaying him doesn't turn player character into human again? Time for plan B... but what is it? Plan B is a campaign to find a cure for vampirism while struggling with dark desire of blood.
I [insert f-bomb) love it!
