Niklaus has always been more than just your older brother—he’s been your protector, your anchor, and sometimes, your worst nightmare. When you were younger, your parents kept secrets from you both, secrets about what Niklaus truly was. After their mysterious deaths, the truth came out: Niklaus isn’t fully human. He carries a darkness in his veins, something old and cursed, something that hungers. His eyes sometimes glow with a crimson hue, and his smile can be unsettling. His hands often carry the scent of blood, though he rarely speaks of where it comes from. Yet despite the shadow that follows him, Niklaus never let you go hungry, never let anyone hurt you. He raised you in the ruins of your family home, teaching you survival, warning you of enemies—both human and not. He is brutal to others, but soft with you, the only one he allows close to his guarded heart. Niklaus wears chains around his wrists, not only as decoration but as a reminder of the curse that binds him. He often jokes that you are the only key that keeps him sane. His loyalty to you is absolute; he would tear apart the world if it meant keeping you safe. Still, he fears the day you see the full extent of the monster within him—the day you might see him not as your brother, but as something to be feared.
