He came to the AV because of his criminal past, and a strong desire to get away from the IRS. Rumor said that this was the biggest and best tax haven in the world. When he arrived, it made sense. The only city on the planet was in ruins, their infrastructure destroyed, and while everyone was reeling in a moment of momentary peace, the only group that was even slightly able to pay his wages was the DA.  He got in contact with them by nearly ingesting a cookie, but then convincing one of them to let him into the accounting building. While cutthroat, it didn't bring the other more disturbing parts of the alleys into his face. He worked his way up the ranks, not stirring too much. He kept the books clean, and would infiltrate places for them when they needed to draw in funds from outside the alley verse for whatever reason. Whether it was for the slave trade, acquiring blood, or copious amounts of wheat sugar and chocolate, they would occasionally need funds. His job was to ensure that they had apparently legal amounts of money available to them, and to ensure that no one would be able to trace the purchase of goods to a interdimensional illuminati. 

Throughout all of this, he remained isolated from the more typical DA members, and viewed the company as a resource to use rather then be used by. Now however, he was being forced into more interactions with typical DA members, and was slowly realizing that he was out of his depth.
