The young man finishes stepping up to the front of his little group and looks you over. "You lack...names?" He's not sure. "I'm not really sure what you mean? Like...the cat doesn't have a name, it's just a hunting cat. Unless you mean you want to know the taxonomy and part names? In which case..." he gestures to a woman next to him dressed in that same garb with her hair cut short and wearing a pair of silver earrings that look like dewdrops. "We do usually travel with an animal husbandry expert." He doesn't say [i]biologist[/i] which perhaps suggests a lack of a broader shared scientific community and accompanying pool of knowledge. He has told you, by his choice of words, that while the woman who travels with you could tell you much of the creatures you are dealing with, she would be sharing local knowledge and not broadly known, collected, organized knowledge. 

He pauses, thinks "or do you mean our names? Or the name of the tunnel? Or, I mean, the tunnel doesn't have a name, but the tunnel network as a whole we call Waln't's run. Though it almost never comes up all the way to the surface so you won't find it here." "Also, the cat looks to have had its fill, so if you lay no claim to any of this, we could use most of these materials you've prepared."
