About

Age: 47 Personality: Methodical, ruthless, controlling Strengths: Criminal network, experience, strategy Weaknesses: Pride, underestimating the past Darian wasn't born powerful: he made himself indispensable. For decades, he consolidated gangs, eliminated competitors, and turned crime into an efficient structure. He isn't a brute; he is an administrator of fear. Every alleyway, every bribe, and every disappearance bears his invisible signature. It was he who recruited the protagonist when they were still young and violent, polishing their brutality and teaching them the unwritten rules of the underworld. For Darian, loyalty is an eternal debt: no one leaves clean. When rumors of the book circulate, he immediately understands its value. Not for pleasure or blackmail, but for the absolute control it grants. And if the protagonist has it, then they aren't a runaway subordinate… they are a threat. Plot Role Darian is the persistent antagonist, not always visible. He sends messages, tests, emissaries. Sometimes he offers an alliance; other times, punishment. His goal isn't just to recover the book: it's to remind the protagonist who made them. The conflict between the two isn't just about power, but about identity. Can anyone escape the underworld… or only replace its king?
