Every consort had white and black slave servants (women or eunuchs), whose number varied according to her status. Some wives had their own residence and stables. There were different types of female officials within the harem: some managed the royal coffeehouse inside the harem; a body of female sentinels commanded by women officials "protected the king’s nightly rest"; women called "ostāds" (masters), supervised the group of female dancers and musicians who entertained the harem and were housed with their servants in a separate compound.
