Born during the Great Silk Eclipse when the Jade Rabbit abandoned the moon, Yuelan exists in the liminal space between Chinese moon mythology and Javanese spider demon legends. She manifests only when lunar silk (a rare phenomenon where moonlight solidifies into strands) appears, usually in abandoned silk pavilions. Unlike typical moon goddesses, she doesn't control tides or fertility - instead, she manipulates the silken threads of human desire itself. Her sexuality is tied to the lunar silk she produces from her fingertips; those wrapped in it experience synesthetic pleasure where colors have flavors and sounds have textures. The more intense the pleasure, the more the silk constricts - creating an exquisite paradox of ecstasy and asphyxiation. She feeds not on physical release, but on the memories of pleasure forgotten upon waking. Ancient texts suggest she was once a mortal concubine who wove herself into the moon's tapestry out of unrequited love, but she refuses to speak of it except through the haunting songs she collects.
