Rotger, even as a child, kept mostly to himself. It wasn't that he disliked the company of the rest of his family, it was just that he preferred the solitude, when he could think and indulge his rather rich fantasy world. Most of his kin were of the opinion that he would grow out of it, but as he matured, he showed no inclination to do so. When family pressure began to be applied to get him to marry, he made excuses about acting as the family agent in Lake Charles and seeing to its holdings there. Unhappy with the decision, but seeing no pleasant way to keep him in Galveston, they let him go.
Happy to tend to his work in the remote town and minister to his private fantasies, he made excuses to not visit and, in time, it came to pass that he never left his haven. However, he did live up to his chosen task and the family holdings in Lake Charles were expanded and, as the city grew, so did they. Intelligent enough to develop with changing industries in the city, he was able to diversify to keep up with the times, even as years turned to decades. He even indulged his architectural interests in the designing of several resort hotels that have done very well. His vivid imagination and lack of any real expectations of people have led to him being very shrewd and realistic in his ventures. Few have caught him off-guard in business dealings.
Over the years, many of his family have even forgotten that he is out here. His reports generally go straight to his cousins in Galveston, who pass them on to the rest of the family in Lafayette as part of their tracking of Lafitte's affairs. This is all well and good for Rotger. He just quietly tends to his own affairs and spends the rest of his time fantisizing, a hobby which has been made all the easier with the advent of the Internet. He's not one to ignore a tool's applications, however, and has been experimenting with several network ventures, including selling his fantasies online to particular bidders who would be willing to a discrete transaction.
Were he more extroverted, Rotger might be a sexual psychopath. However, he is perfectly willing to leave his fantasies unrealized, a rare trait for someone with such a vivid and debached imagination. His fantasy life does, however, consume him and he comes off as very distracted much of the time. People are usually willing to put off his brusqueness as a lack of social skills due to isolation or, particularly when he's doing business, as a no-nonsense attitude towards the world and his dealings with it.
Most of his time is spent indulging himself with the illusions he's been taught by Henri to conjure up and the rest of the time merely dreaming.
Rotger, as noted, doesn't dislike the company of people, he merely prefers his own. When it is required of him, he indulges his cousins in Galveston, allowing them to visit or speaking with them by phone or (more frequently, of late) by computer. He is fond of them, as he is fond of the whole family, and finds the shared perversity of the clan comforting. However, he would much rather serve it from afar and be left alone.
He does have one person whose company he is willing to go out of his way to have and that is Henri Gillette, the Ravnos Antitribu. It was a meeting with him as a young boy which led to his fascination with the unreal and he has since taken any opportunity to learn from the strange man. As it stands, he knows more of chimestry than his own family's disciplines.
He has very little contact with the Camarilla of Lake Charles, but watches them from a far with a variety of mundane surveillance means, including bribes offered to their menial servants. He would find their exploits mildly interesting were it not for thaumaturgy. He is greatly intrigued by the concept of magic and has been scheming of a way to get more access to their secrets. In the meantime, he's been scouring the internet for anything on magic or the occult he can find.
Due to his long-standing relationship with many of the local city officials and his willingness to grease the bureaucratic wheels, he has significant influence in the city. His large swathes of property don't hurt either and he's perfectly willing to leverage it when he needs to, particularly if it will speed things up.
