Here are the details on the guy hired by you and Tison (presuming that you shared the effort and Tison did much negotiation while Caernak prayed):
Enestaki Oddusson, Sartarite expatriot river-merchant, age 35 (in 1625). Initiate of Issaries Goldentongue. Bargain skill 80, Fast Talk 70, Human Lore 60., Evaluate 95. A good talker and knowledgable about the river (River Lore 55). Avoids physical combat like the plague (Cowardly 16) but loves verbal combat (Argumentative 15; passion). Strongest connections are with Orlanthi farming communities in Pavis county, the Uz Mercantile Association in Pavis and related troll merchants in Corflu, and the river folk. Not fond of dealing with Lunars, Sun Domers, or nomads. Speaks Tradetalk (80), Sartarite (70), Boatspeech (50), Darktongue (50), New Pelorian (45), Pavic (30), and Praxian (15). Reads most of those, too. Shrewd but not overly deceitful or honest either. A pragmatist. Has spent a lot of time in Corflu lately buying + selling odd curios from across the sea, and has an eye for magical goods. (Knows Detect Magic and some uses of Analyze Magic, etc.). He seems trustworthy and motivated, but is just as shrewd negotiating with you as he is with his customers, so he pushes hard for getting his share of all deals. He likes Mru and other peaceful folk; violent folk scare him too much. So apparently he deals with fairly pacifistic trolls, or at least works in daylight only.
Anyway, that's who you got from the limited pool of potential contacts in Corflu.
