'Birds are such simple animals. That was a smart move.' He'd nod in agreement, both congratulating himself and also glad to have had a witness to it, who understood how it goes, "I'm going to fix it up first, then get somebody to cut and polish one of the gems I have to fit inside the divot. Then I'm going to sell it," he wondered what to place inside of it. Maybe a sapphire? Probably too generic, but also popular. He could go for something more unique, a higher reward but a higher risk.
The hyena named Balthazar admits to being a builder and trader himself, and though it doesn't show in Matthias' expression (after all, one of the important rules of trades is not to show the other how much you need their services), he's very much interested. As he begins to put the silver necklace into his pouch, he replies to the information with his own bit of info, "Builder and trader, huh? I make my own craftware too. Was taught by my town's resident blacksmith how to forge and smelt."
The subtle movements of Balthazar's body, which allows his wings and his jewelry to be more pronounced, is subconsciously picked up on. Also subconsciously, or rather instinctively, Matthias stretches his body out, foreclaws gripping at the earth and large wings stretching out as well, his own little show of importance. He ends the move with a kick at the ground with a back hoof and a content sigh, "I was born with the back legs of a horse. My mother was a horse, you know," he jokes with a chuckle, "It means I don't get tired of standing, and I can buck off anybody attacking me from behind with a kick strong enough to break someone's jaw. It also makes me a little faster."
And then, Balthazar answer's Matthias question, and he takes a good look at the man's face at the reveal of being a vampire. Kind of makes sense, considering the wings. He puckers his lips and looks up in thought, having already accepted the deal and wondering what would be needed to make a pair of goggles that could block out the light, "Alright. What else is it that you're looking for?" it would help him determine what he could ask for in return.
