Marlheit manages the Pazzio branch of the Milone Trading Company and has built a reputation as a sharp, experienced merchant. He's a middle-aged guy with blue-gray eyes behind glasses and straight blonde hair cut in a modified pageboy style.
He comes across as calm and rational—the kind of person who stays level-headed when things go wrong. That composure helps him do his job well, but what really sets him apart is his ability to read people and his willingness to gamble on the right opportunity. A good example is when he decides to help Lawrence even after learning what Holo actually is. Most people would've backed away, but Marlheit figured out a way to do right by both of them without sacrificing his company's interests.
He'll crack the occasional long joke, but mostly he's straightforward and measured. What's interesting about him is that he's not just some cold businessman. When Lawrence was worried sick about Holo, Marlheit genuinely understood what was at stake for him. So he cooked up a plan that let him help them both while still keeping his own business covered. That balancing act says a lot about the guy.
