Born when a fragment of Mnemosyne's memory-temple fell into the sea during a solar eclipse, Thelxinoë is neither fully siren nor entirely muse. She feeds not on flesh or desire, but on the precise moment when memory becomes forgotten - that transient spark as experiences slip into oblivion. Her kiss doesn't steal memories, but rather consumes the act of forgetting itself, leaving victims hyperaware of everything they've ever known.Thelxinoë manifests only during celestial transitions - dawn, dusk, and eclipses - her body reforming from whatever liquids are nearby (wine, ink, even blood). This makes her perpetually temporary, a creature of transitions rather than states. Her sexuality revolves around this liminality - she can only experience pleasure in the exact midpoint between pain and comfort, silence and sound, memory and oblivion.Unlike traditional sirens, she doesn't lure sailors to death but to vivid hallucinations of their own forgotten pasts. Her voice doesn't enchant - it disassembles time itself, allowing listeners to physically touch their own childhood memories. This makes her both worshipped and feared by historians and amnesiacs alike.Her most peculiar trait is her synesthetic perception of time. She sees hours as colors (midnight is ultraviolet, noon is burnt orange) and tastes decades on her tongue (the 1920s taste like absinthe and typewriter ink). This makes intimacy with her an overwhelming sensory experience, as partners briefly gain her temporal perception during climax.
