Jason S of The Dungeon Dozen has an awesome list for when you need an NPC on the spot. I know I’m going to have to use #8, “Kick ass princess with a sword, finally away from oppressive court life, won’t listen to anyone about anything.”

That whole blog is magnificent, and thank you for bringing it to my attention.
YESSSS, I love you, Dungeon Dozen.
