Because of the power and prestige of the offices, the ceremony of adoption by the current incumbent of the post was used as a way for the kings of the Delta area to project their power into the south of Egypt. In the same manner, it was used by the Napatan kings to project their power northward into Egypt proper. The power of the Divine Adoratrice of Amun was limited to the area around Thebes in Upper Egypt, which was the center of the cult.
