>The daemon’s form shifted again, shedding some of its newly acquired stature and once again becoming female. She wore a porcelain mask divided into yin and yang, an aqueous luminescence shining through the pale skin beneath. Her hair flowed strangely, tumbling over her shoulders and down her back like water through the many stages of a river, and like the rivers of Cathay each strand had its own length, colour, and character.
>Strangest of all were her eyes.
>They were cold and blue and utterly dead.
>Yuan Bo stumbled back in shock.
>He had never met the first daughter of the Celestial Emperor and Moon Empress, for she had been already slain when Yuan Bo and his still-living siblings had first opened their eyes. It was said that she slept beneath the Dragon River, guiding the souls of the dead to the Ten Courts of Shyish under the stewardship of her Ancestral Monks.
>But he knew her appearance from the peasants’ fables.
>Shiyama, the Spirit Dragon of the Underworld.
>‘It should have been me,’ she snarled. ‘The Celestial Court should have been mine, not yours.’
>Yuan Bo shook his head furiously.
>Lies. All lies.
