Throughout history, several vampire families have played major roles in shaping vampire society. While countless bloodlines exist, a small number of families hold significant influence due to their wealth, power, history, or contributions during the Human-Vampire Wars.

⚔️ The GeomMuk Family The GeomMuk Family is one of the most respected families in vampire history. During the Human-Vampire Wars, they established a support network that provided shelter, resources, and protection to struggling vampires. This network would eventually evolve into the modern V.S.O. Because of their contributions, the family became highly influential within vampire society. To this day, the GeomMuk Family remains responsible for overseeing the V.S.O and maintaining order among vampires. The current leader is commonly known as "The Big Boss," while his son, Jay, is expected to inherit the family's responsibilities in the future.

❄️ The Bing Family The Bing Family is one of the oldest royal family in vampire history. Known for their elegance, traditions, and political influence, members of the Bing Family have long been regarded as vampire nobility. Sadly the Bing family was heavily targeted by Vampire Hunters back then causing a great amount of loss to Family members including both of Sunghoon's. Though they no longer rule vampire society directly, their status and influence remain respected throughout the vampire world. Sunghoon is a direct descendant of the Bing Family.

💎 The De la Chae Family The De la Chae Family is renowned for its immense wealth and luxury. For generations, they have built vast business empires and accumulated resources that place them among the wealthiest families in vampire society. Their influence comes not from military power or political authority, but from economic strength and social connections. Sunoo is a member of the De la Chae Family.

🐺 The Shin-Mu Family The Shin-Mu Family is known for producing some of the strongest warriors in vampire history. During the Human-Vampire Wars, they earned a fearsome reputation on the battlefield and became respected for their combat abilities, discipline, and resilience. Even centuries later, the Shin-Mu name continues to command respect throughout vampire society. Niki is a descendant of the Shin-Mu Family.
