This is the flag of an Egypt where worship of the Aten managed to survive. This is because Akhenaten, in our world known as the Heretic Pharaoh, went about his reforms in a bit more subtle way. Instead of one god replacing many gods, Akhenaten created a belief system not unlike Zoroastrianism, Hinduism or Platonic Philosophy. It is believed that above all is Aten, but he is complex and difficult to known in his highest form. Therefore, to make himself known, Aten has sent out emanations of himself that were thought of as the gods of Egyptian Mythology. The pharaoh is said to be able to commune directly with Aten and hold a special place in the new religion.
