"Stealing stuff is fun. Killing creatures is fun. Getting away with it, though? That's amazing. And so, to aid you in performing even more-unlikely escapes while acquainting you with some of the stranger forces in the world, I am pleased to offer for your consideration the Umbral Infiltrator. Because it's fun to be the best at stealing things, it's fun to be the best at messing with people, it's fun to be the best at shanking your foes, but you can never have that fun again if you get caught or, more humiliating still, ambushed yourself. It's nice to have a party to back you up, but the shadows are even more reliable." (Author Summary)
