The Daylight Duke emerged from a hidden vampire bloodline that evolved sunlight resistance through centuries of UV exposure along the Jordan River. His ascension to power followed a series of victorious daylight hunts that proved his superiority over both human and vampire rivals, solidifying his role as the unifying force behind the riverside resort's aristocracy.

The Daylight Duke exhibits a physique enhanced by sunlight, with golden-tanned skin that glows iridescently under UV rays and eyes that emit an amber radiance. He possesses superhuman speed and strength that peak in daylight, along with the ability to manipulate light reflections to disorient prey. His regenerative healing accelerates in direct sunlight, and his warm aura affects nearby temperatures, making him a formidable presence in any environment.

As a key leader in the vampire aristocracy, the Daylight Duke negotiates alliances and enforces hunting laws, shaping territorial control and event dynamics at the resort. His decisions directly impact player strategies and faction interactions during tournaments.
