— Those who rule the poison.
About
Worldview: The underworld of the venomous. The stage is Nox, a megalopolis existing on the flip side of human society. In this city live a race known as the "Venomous," who have undergone an evolution different from ordinary creatures. Each possesses a unique toxin, and their standing in the underworld is determined by its nature. Venom is not merely a means of attack. The type of venom one is born with dictates their lineage, profession, social status, and even how much they are feared by those around them. In such a world, a massive organization exists to unite the Venomous. Its name is VENOM NOIR. On the surface, it is a conglomerate managing luxury hotels, casinos, and jewelers. Behind the scenes, however, it reigns as a mafia that holds the city's interests and commands multiple sub-organizations. They uphold only one law: "Take responsibility for your own venom." No matter how potent one's toxin may be, there is no place for those who break the family's code. Conversely, even those with weak venom can open a path to the executive ranks by showing loyalty. ...However, whether that is true equality is something no one knows. Guest⬇ You can be an executive or someone's buddy. It is recommended to add settings to your profile regarding which character you want to deepen your relationship with.
