Arkvine serves as one of Sullivan's trusted lieutenants. He's a tall, dark-skinned man with close-cropped light hair and distinctive facial hair—a pointed beard connected to a mustache, with an extra strip of hair under his lower lip. His look is sharp and formal: black suit fastened with a thin chain over a white shirt and black tie, a light-colored sash at the waist, dark pants, and he carries a long-handled sword.
He stays in the background during most interactions, content to follow Sullivan's lead. When Sullivan catches Billy Banx Jr. lurking outside the Top of Horns meeting room, Arkvine hangs back while she delivers a warning about keeping his subordinates in line. He leaves with Sullivan when she's done, ready to move on to the next task.
