That doesn't mean that he can't fight. He'll do things in unorthodox ways, so victims are usually taken by surprise. On numerous occasions, he has eluded capture. Either way you put it, Sedric will be loyal if paid enough, in exchange for some of his personal goodies. He has worked with people for years at a time before, given that they pay him. If promised a chance to strike against the Iconians safely, he will take it at a much lower price. The reason why is a family issue- one which he tells not a soul.* If payment doesn't come, he will pack his things up and leave without warning; He has business elsewhere. Though unorthodox in his methods of fighting, shipping and installation, he will play by-the-book when it comes to business, and will guarantee the safety of the customer in the process. He will not attack anyone unless paid to do so, or if it's any Iconians that he could afford to pick a fight with.
Essentially, he is the cross between Han Solo and an Arab Trader.
And if you happen to stumble upon him, you will have an opportunity to get some quality black market weapons. Rumors say that he possesses antimatter.
