Conceptualized for a game as an advisory character to a higher up persona and potential party liason... Adrian didn't really take on a life of his own until I had to ask myself the question "How are they going to deal with this situation?" Leading to the broader notion of how they take care of things and ensure that their clients/benefactors are protected. I still couldn't tell you much about them... they never had too substantial a role. But I better understand how to play their personality now and I feel like I could translate that well enough into other settings, should I have a need for a similar character.
....I should of drawn a version of him in a nice modern suit or something, but my head was stuck in more fantasy era places at the time....
