Serge, Sim and Adrian have all seen me kill wights and I've done a fair sight more than that concerning the living dead... I admit that I'm not a wizard who can level fireballs and  blast of ice, but when you've used all of your spells, I'll still be standing and fighting with my wits and little blades... and keeping them off of you while you contemplate what to do next..." She leaned forward and lowered her voice as if passing something secretive, "I'm the one who'll stand between you and their touch... the one who dies first for her crewmates... are you willing to promise the same?"
