Rudolph Van Richten AKA Rictavio

At first meeting this colorful fellow presented himself as "Rictavio!" traveling ringmaster of his cabinet of curiosities. He regaled the patrons of the Blue Water Inn with tales of adventure, excitement, and tragedy.
Shortly after your arrival in the town of Vallaki, and after you had ingratiated yourselves with him and spoke of your opposition to the Devil Strahd, Rictavio revealed himself to be "Rudolph Van Richten" famed monster hunter.
Little is known of him to you as of yet, but his reputation for being a totally bad ass dude precedes himself.
