Sanctuary Assassins Guild

There is no Assassins Guild in Sanctuary. However, everyone who is anyone has bodyguards, astrology, and death curses. Some pay death insurance to local witches or necromancers, to ensure they have company in the afterlife. There are many hundreds of locals who would kill for money, and dozens of professionals, so you should be very clear why you can succeed, when others haven't already, in this magic-rich, moneyed, paranoid cesspit.
