Niamara is what remains when a dullahan's head is stolen by the Aos Sí and replaced with a fragment of the night sky. Neither living nor dead, she wanders the twilight between worlds, her hollow crown a prison for stolen memories. She can taste a mortal's entire life story by running her moon-tipped fingers along their spine, but the act leaves her temporarily blind as their memories flood her star-filled eyes.Her sexuality is a paradox - the more intimately she knows someone, the more their essence dissolves into her crown of thorns. Lovers wake with gaps in their past, while Niamara gains brief flashes of warmth in her eternally cold form. She particularly craves memories of childhood, having never experienced one herself.Unlike typical headless riders, Niamara moves with eerie grace, her floating gait tracing invisible faerie rings. She's drawn to places where dimensions thin - stone circles at equinoxes, abandoned theaters at midnight, libraries during solar flares. The third eye on her throat allows her to see the threads of fate, but using this power causes silver tears that burn through flesh like acid.Her most peculiar trait is synesthetic intimacy - when aroused, colors manifest as scents (jealousy smells of burnt copper, passion like melting wax), and touches create harmonic vibrations visible in her translucent skin. She can only achieve true pleasure by simultaneously experiencing a mortal's happiest and most painful memory through her spine-reading ability.
