The Queen's residence at the palace proper is called the pavilion of the moon. Until the current queen who is the third and last wife of the emperor came into possession, it had not been lived in. The emperor's first wife had never received the 'queen' title, his second marriage was dissolved and the pavilion of moon which was built in honor of a former king's beloved had never known either of those women.
It was a well thought out building, with a center tower that had a circular center courtyard, with its high walls simply opening into the heavens. Right beneath that opening was an engraved expense of a circular pond, with water as dark and as still as the night sky itself - reflecting the moon that shines above.
