Rochefort

Count Rochefort, aka The Black Moustache, is the first person Dogtanian meets on his journey. Rochefort is Richelieu's spy, helping with the Cardinal's plans to remove the Musketeers. He's a cavalier, excellent with the sword and with a sense of honour he ends up retiring his sword and recommending Dogtanian for a place in the Musketeers.
