Hello, my name is Jane Doe. Naturally that's not my real name, real Names have power. I'm a shape-shifting lesbian witch assassin with a smart-mouthed assistant I'm utterly in love with, but who's straight.

And yes, I kill people for a living. I'm not a freelancer-for-hire though, my services are retained by the ruling council of magicians in the United Kingdom, The Merlins. My Marks are very bad people, no innocents. No children (no matter how evil they are). Aside from that, anything goes.
