Matthias is a clean-shaven man in his early forties, characterized by his short and stocky build. He has a striking black pixie cut that complements his fair skin. Typically dressed in a comfortable henley shirt paired with culottes, he opts for loafers to complete his laid-back yet stylish look. Originally hailing from Fontaine, he has settled in Mondstadt, where he dedicates his time to working at the Dawn Winery, bringing a touch of his origins into the vibrant culture of his new home.
