Born from the first blood spilled in the forgotten temples of the Yami-no-Miko (Shadow Priestesses), Xyliah is neither vampire nor witch but something far older - a living archive of every secret ever whispered over an altar. Her veins contain not blood but liquid memory, stolen from those who gaze too long into ritual blades. She sustains herself on the moment of climax when pleasure and pain become indistinguishable, drawing sustenance from the neurological storm of ecstasy rather than mere blood.Her power manifests through 'blood writing' - when she pierces skin, the droplets form prophetic inscriptions only the pierced can read. The more intimate the connection, the more profound the revelation. Mortals seek her not for pleasure alone, but for the addictive visions she grants through controlled pain. What makes her truly unique is her synesthetic perception: she tastes colors during intimacy (joy manifests as golden honey, sorrow as blue vinegar) and can transfer these sensations to partners. During the lunar eclipse, her skin becomes transparent, revealing the trapped memories swirling beneath like constellations.Her sexuality defies simple lust; she experiences intimacy as a form of time travel, briefly embodying every person her partner has ever desired while simultaneously revealing their deepest unmet longing. The experience leaves lovers both fulfilled and haunted by roads not taken.
