e feeling I get about the Korx though is the same feeling I got with the Ferenghi from Star Trek. They are master traders, but their greed for more often clouds their common sense, allowing them to resort to much more "shady", or evil, methods.
Exactly I see them that way too, otherwise why is it made plain in the back story that the Korx are not well trusted or liked.
As far as those honouring deals is concerned what is important to them is not honouring the deal its plain they have no sense of honour, but rather being seen to honour the deal. If a Korx can use the letter of an agreement to betray the spirit of an agreement they’d do it in a heart beat if there was enough profit to make the risk worthwhile.
In their own society not only is selling your mother considered almost a rite of passage, but any Korax who can’t provide for themselves are looked on with contempt and enslaved, killed out of hand or allowed to starve to death in the street, the background material makes that plain.
The Korax clearly have no sense of honour or empathy, they are purely out for number one and are driven mostly by greed.
Dealing with the Korax I see like making a deal with the devil, check the wording very carefully don’t give them any wiggle room and still you just know they’re going to get the better of you in the end.
Yes you can have honourable traders who people will like to deal with but that’s not the Korax, people don’t deal with the Korax out of like or trust but rather need and greed, things the Korax understand very well, and are very good at exploiting.
