Hey, can we hire you to kill people?
Of course, then you'd probably get outlawed from whichever city, which wouldn't be that fun... Ooh, we should totally have like darkelf assassins we can hire, maybe in Ironhold if you've got the right alignment. Mwahaha... I guess there are mercenaries there. And people probably want to avoid more NPCs killing people without the PC being involved. I kind of like the idea of anonymous hits though.
