Yes, he knows many people, and many...creatures, many of which you'll meet as the story progresses. Some you'd consider to be good. Some, you'd consider to be evil. The interesting aspect of his personality is that he accepts people, and things, for who and what they are. He doesn't try to change people. He sees value in both the good and the bad, and he'll accept evil people as long as they're not evil to HIM.
That's why he hates the Harpers. They want to change things to create their "perfect world," not seeing the beauty of it the way it is now. But they don't see that by trying to stamp out evil, they're perpetrating the same evil they profess to hate.
At least that's his opinion.

In AD&D terms, Fox is Neutral with Good tendencies. He doesn't hold much water to rules, follows his own whims and fancies, but he's also a kind person who'd give you the shirt off his back if you needed it. Where most people would try to kill an orc that wandered into their camp, Fox would invite him to sit down and share dinner and have a talk.
