Mr. Thresix

Mr. Thresix is a vampire who runs Sutter's Casino and is associated with the Ivy Mafia. He is the contract holder for dozens of people, including Lyla Young. He is known for his heavy Bronx accent and teenager-like appearance. He is the older identity of Sullivan Dean from Camp Wildwoods. Unlike Sullivan, he appears to have foregone his reluctance to drinking blood, and he does not have much concern or sympathy for people.

Relationships

Mr. Thresix is the contractor holder for many people, though he has personal relationships with very few. He appears to have a soft spot for Carson and Reno Holloway. In the Furthermore Chapters, Carson refers to him as "Uncle Sully".

Abilities

Mr. Thresix is very manipulative and has a large network of contracted employees. His influence stretches across the U.S., and he is also physically very quick. He is vulnerable to sunlight, as all vampires are, and later recruits Mr. Frost to find him a UV blocker charm that will allow him to safely travel in daylight.
