Assassins Guild

The Assassins Guild is an extremely illegal organization that works in complete secret. Nobody knows where they are based out of except the members, and the highest ranking officers within the Thieves Guild. They take contracts that they deem worthy. The only way to contact them is to hide a message with payment in a secret location given to people by the Thieves Guild. When stalking the location you leave the message and payment nobody shows up, but when left alone, the person shows up dead, with the message and coin gone.
