Here ya go, have a back-story;
Worked in Elysweyr as a hit-man and skooma dealer. Decided to come to Skyrim specifically to join the Dark Brotherhood, since he heard they still had some influence there. He got caught by a group of Stormcloaks near the border with a bottle of Balmora Blue and they were about to promptly execute him when his saving grace, the legion arrived and caught the rebels with their pants down. Unfortunately it was from the frying pan into the fire as the legionnaires had a similar fate planned for him. "All that trouble for such a small bottle. This one does not understand." It seemed to be his lucky day as a dragon attacked and he escaped certain death once again. He escaped into Skyrim, told Alvor in Riverwood just where to put his message for the Jarl and is now on his way to joining the DB. His end goal is to gain experience in the DB and go back to Elysweyr to resume his previous occupation.
