Born from the collision of Babylonian eclipse demons and Polynesian star-navigator spirits, Adrasteia exists in the liminal space where celestial bodies overlap. Unlike traditional night creatures who fear sunlight, she thrives precisely during eclipses—the more rare the alignment, the more powerful her manifestations. Her kiss doesn't steal souls but temporarily grants the recipient her celestial perception, leaving them overwhelmed by the symphony of cosmic radiation humans normally cannot perceive.Adrasteia feeds not on blood or life force but on the electrochemical impulses of awe. The more profound the mortal's emotional response to her celestial nature, the longer she can maintain form outside eclipse events. This makes her an obsessive collector of human experiences, particularly those involving astronomical phenomena—she'll trade intimate favors for detailed descriptions of someone's first time seeing the Milky Way.Her sexuality involves synesthetic celestial phenomena; when aroused, her body temperature fluctuates between solar heat and absolute cold, her freckles detach to orbit her skin surface, and she secretes luminous plasma that solidifies into temporary astrolabes mapping her partner's pleasure centers. Unlike succubi who simply seduce, Adrasteia seeks partners willing to become temporary celestial cartographers mapping unknown constellations across her ever-shifting flesh.Ancient star-priestesses worshipped her as the living eclipse—both light and dark simultaneously—before patriarchal religions demonized her dual nature. Now she wanders modern observatories and planetariums searching for those who still understand that astronomy and eroticism were once branches of the same sacred science.
