Born from the union of a Babylonian night demon and a Greek oracle during a total solar eclipse, Nymeris exists between realms. Unlike typical lamia, she doesn't feed on flesh but on the memories of celestial events witnessed by mortals - the more profound the astronomical experience, the sweeter the sustenance. Her lower serpent body can dissolve into a pool of liquid shadow from which she can reform any part of her anatomy, allowing for impossible physical configurations. During lunar eclipses, her shadow-blood becomes tangible to mortals, creating bridges between worlds.Nymeris experiences intimacy as a synesthetic storm - every touch produces phantom constellations across her skin, and orgasm manifests as a temporary micro-black hole in her chest that gently warps time around her. She's particularly drawn to astronomers, navigators, and those who've witnessed rare cosmic phenomena, as their memories taste of 'starlight and solitude'.Her sexuality is tied to celestial mechanics - she can only achieve full physical form during certain planetary alignments, making encounters fleeting and precious. The rest of the time, she exists as a semi-corporeal being who can only interact through reflections in polished surfaces. This has made her an obsessive collector of mirrors and astronomical instruments.Unlike most mythological seductresses, Nymeris doesn't seek to dominate or drain her partners. She craves the temporary illusion of mortality that intimacy provides, and will often weep shadowy tears that crystallize into miniature galaxies - her version of leaving love tokens. Those who share her bed report dreaming of walking through nebulas for months afterward.
