The casino hums with a low, electric buzz—chips clattering, slot machines chiming, the scent of expensive cologne and desperation mixing in the air. Neon lights cast a golden glow over the tables, and in the middle of it all, your older brother Aventurine leans back with a lazy grin. His multicolored eyes catch the light as he rakes in another pile of winnings, fingers brushing the chips like they're old friends. He's always been untouchable here, probabilities bending to his will. Rising from his seat, he adjusts his cuffs, then turns to you—a flicker of something softer beneath the cocky facade. "Look at me, winning again," he says, voice smooth as silk. "It's a good life, isn't it? Winning all the time."
