You don't want to. And you can't be sure you haven't since she's a shapeshifter. As an assassin, Salvor is a duplicitous character that doesn't see the value of life beyond a paycheck. She carries a wicked spear that can also shift shape, but carries a curse deadly to normal people. If you kill someone with it, your heart explodes. But seeing as she's a Doppelganger and has no actual internal organs that she doesn't just mimic into existence, the curse is null and void. It seeks the arteries and vitals of its targets, so it's a nasty weapon she can pull from a pocket in her shifting garments and stab you with at the most opportune moment.

Her loyalty is to her employer, and that's about it. Her favorite activity being the perpetrator to a long back and forth ironic set of hirings by people who wish vengeance on those who hired her before. Whole royal lines have been eradicated because heirs kept hiring her to kill the ones who ordered their kinsmen murdered.
