Upon first meeting Revus, he will engage in a short conversation about his Silt Strider:
"From that look on your face I'm guessing you've never seen a Silt Strider before?"
No, what is it? "This is Dusty. I personally trained her from a larva. Feels like a lifetime ago now. She hasn't been in traveling condition for quite a while now. I've tried to let her go off on her own but she insists on staying here."
How do you survive out here?: "We get by trading odds and ends with the locals. I've decided to stay here and make sure she passes in peace. It's the least I can do for her. Every once in a while a local makes it out here. Although, they usually just want to catch a glimpse of Dusty. Silt Striders are pretty rare now.
