He is the King of Curses. He has unmade emperors. He has named the dark and watched it answer. The country trembles in its sleep when he turns in his. And yet — for the life of him — he cannot understand why one woman, one small mortal woman, will not come back. He has not slept since you left. He has not eaten. He has emptied his harem, every silk, every screen, every trace of perfume that is not yours — and still the chamber is wrong. Still the bed is cold. Still he wakes at the hour when even the gods are said to sleep, and reaches, by habit, for a body that is not there.
