Salem nodded and held out his hand, "Pleased to meet you, Jocun. I typically trade in... well, anything potentially valuable. Not currency. Currency is only useful within the society for which it was designed. Technologies, information, artifacts... anything you might think valuable, I'll at least look at, and offer something in kind." He bowed his head slightly and smiled, "And I do understand the importance of protecting one's technological advantages. I wouldn't be a very good trading partner if I were to just turn around and sell what I receive to your opposition. If we need to draw up contracts for you to feel comfortable trading with me, so be it, but there is no contract more binding than my word."
He cracked his knuckles and looked around, grinning, "So, is there anything you'd like from me? Or anything you'd be willing to offer me? I usually start with small trades- DNA for a trinket, for example- just to make my partners comfortable. If you're willing to consider a more substantial offer, we can just jump right in, as far as I'm concerned."
