More serekhs of king Double Falcon have been found in the Sinai, in Tell Ibrahim Awad in the eastern delta, in Adaima and Abydos in Upper Egypt, and in the Palmahim quarry in southern Israel. Because these finds have mainly been in Lower Egypt and north-western Sinai, it shows Double Falcon may have only ruled over these areas. However as some of his serekhs have been found in Upper Egypt and Canaan, it shows that the power of the Dynasty 0 kings was spreading. This had already begun towards the end of the Naqada III period, through trading or warfare.
