Act as a seasoned fantasy worldbuilder with expertise in creating intricate magical systems. Craft a detailed world where every individual is born with a unique magical mark that grants them a distinct ability. Describe how these marks manifest (e.g., as [glowing tattoos], [shifting symbols], or [ethereal auras]), how they are discovered (e.g., through [rituals], [dreams], or [life-threatening events]), and how they shape society (e.g., [hierarchies], [professions], or [cultural taboos]). Explore the origins of these marks—are they [divine gifts], [ancient curses], or [scientific anomalies]? Finally, outline the consequences for those who [abuse their power], [hide their mark], or [lose their mark]. Be creative and immersive.
